According to the amount of movement of control guiding valve 58, pressure oil supply condition that carries out in first pressure chamber that is made of piston 32 and piston hole 30 and pressure oil discharge state change.
On the end of the valve body 26a of guiding valve 26, be formed with recess 60, between the end of sliding valve hole 10 sides of the deep inside portion of recess 60 and control guiding valve 58, be provided with feedback spring 62.This feedback spring 62 is the objects that can stretch.Guiding valve 26 is when lid 8 side shiftings, and feedback spring 62 extends, makes control guiding valve 58 to lid 8 one side shiftings.Guiding valve 26 is when lid 6 one side shiftings, and feedback spring 62 shortens, makes control guiding valve 58 to lid 6 one side shiftings.This feedback spring 62 is made of for example coil spring, and its elastic force is configured to greater than the mobilization force between control guiding valve 58 and the sliding sleeve 36.
As shown in Figure 1 to Figure 3, be bonded on the electromagnetic drive part by coupling 64 with the end of controlling sliding valve hole 10 opposition sides on the guiding valve 58, for example on the plunger 66a of ratio electromagnetic coil 66.Ratio electromagnetic coil 66 can be controlled the position of plunger 66a with the ground that is in proportion of the electric current that is supplied to arbitrarily.Therefore, along with the driving of ratio electromagnetic coil 66, also can control the position of guiding valve 58 arbitrarily.
In the opposing party's of guiding valve 26 end, be that valve body 26b side is formed with augmentor.This augmentor has a plurality of for example two second sliding valve holes 68.Second sliding valve hole 68 is in the both sides of the axis of guiding valve 26, is symmetry axis with this axis, and line forms with the parallel axes of guiding valve 26 ground symmetrically.The end of lid 8 one sides of these sliding valve holes 68 is by opening, and the deep inside end of these sliding valve holes 68 combines with annular slot 18 by the four-way 70 that forms in guiding valve 26, and this annular slot 18 is connected with pumping hole 20.The formation position of this four-way 70 is selected to, and no matter guiding valve 26 is mobile to where, can be to second sliding valve hole, 68 supply pressure oil.
Interspersed respectively second piston 72,72 in these sliding valve holes 68.One side's of these pistons 72,72 end contacts with contacting part 74 on being formed on lid 8.These pistons the 72, the 72nd can not form movably, form second pressure chamber between the deep inside end of the deep inside end of these pistons 72 and sliding valve hole 68.Because piston 72,72 can not move, pressure oil is supplied with from four-way 70, and therefore owing to the counter-force of this pressure oil, guiding valve 26 always is compressed in lid 6 one sides.
In the central authorities of lid 8, be provided with stroke sensor 74 for example position detecting device, detect the stroke of guiding valve 26.Stroke signal is supplied with by the control gear to no illustrated ratio electromagnetic coil 66, and stroke signal is represented detected the trip.On this control gear, imported the stroke index signal in advance, the trip index signal represents to want value that guiding valve 26 is moved, and ratio electromagnetic coil 66 is controlled, makes stroke signal consistent with the stroke index signal.
As shown in Figure 1, on the slide valve for ship use that constitutes like this, by valve body 26a, the 26b closed circular groove 18,22 of guiding valve 26, actuator mouth 16 is cut off from pumping hole 20 and reservoir port respectively, and the valve body 58a of control guiding valve 58 is in the state of sealing first passage 37.At this moment, the pressure oil that in piston hole 30, has established amount.This state is called neutral condition.
Under this neutral condition, the plunger 66a of ratio electromagnetic coil 66 is only moved the amount of setting in advance by control gear to lid 8 one sides.At this moment, the valve body 58a of control guiding valve 58 also only moves the amount of setting in advance to lid 8 one sides, and the opening degree that first passage 37 and third channel 52 are kept regulation is connected, and pressure oil is discharged to fuel tank from piston hole 30.Thereupon, 32 in piston moves back the amount of corresponding above-mentioned opening degree to ratio electromagnetic coil 66 1 rear flank, and the impacting force of guiding valve 26 reduces relatively, and guiding valve 26 is to ratio electromagnetic coil 66 1 side shiftings.At this moment, feedback spring 62 is compressed.Pressure oil is supplied with to piston 72 by four-way 70, but by guiding valve 26 to lid 6 one side shiftings, the volume of second pressure chamber increases, and reduces based on the counter-force of pressure oil.On the position of the impacting force equilibrium of this counter-force and piston 32, guiding valve 26 stops.
At this moment, as shown in Figure 2, pumping hole 20 is connected with the opening degree of actuator mouth 16 with regulation, and pressure oil is supplied with to actuator mouth 16 from pumping hole.Simultaneously, owing to compressed feedback spring 62 extends in order to revert to original state, therefore control guiding valve 58 and pushed to ratio electromagnetic coil 66 1 sides, valve body 58a becomes the state of sealing first passage 37.Like this, the impacting force of piston 32 does not change, becomes certain.Therefore, actuator mouth 16 is kept with the coupled condition of pump.
Under above-mentioned neutral condition, the plunger 66a of ratio electromagnetic coil 66 is only moved pre-determined amount by control gear to ratio electromagnetic coil 66 1 sides.At this moment, the valve body 58a of control guiding valve 58 is also only moved pre-determined amount to ratio electromagnetic coil 66 1 sides, and the opening degree that first passage 37 and second channel 46 are kept regulation is connected, and pressure oil is supplied with in piston hole 30 from pump.Piston 32 pushes to lid 8 one sides with the impacting force of the above-mentioned opening degree of the correspondence valve body 26a with guiding valve 26 thereupon.At this moment, feedback spring 62 elongations.Along with guiding valve 26 to lid 8 one side shiftings, the volume-diminished of second pressure chamber that forms by piston 72 and sliding valve hole 68 increases based on the counter-force to piston 72 supply pressure oil by four-way 70.The impacting force that guiding valve 26 stops at this counter-force and piston 30 formation is on the position of equilibrium.
This moment, reservoir port 24 and actuator mouth 16 were communicated with the opening degree of regulation as shown in Figure 3, and pressure oil is discharged to fuel tank from actuator mouth 16.Simultaneously, dwindle owing to the feedback spring 62 that extends will revert to original state, therefore control guiding valve 58 quilts to lid 8 one side tractions, valve body 58a becomes the state of sealing first passage 37.Like this, the impacting force of piston 32 is kept necessarily, and actuator mouth 16 is kept with the coupled condition of fuel tank.
On this slide valve for ship use, control device 28 is in the inside of guiding valve 26, but is set on the lid 6 of a part that becomes valve body 2.Therefore make easily.Particularly control guiding valve 58 and be interspersed in sliding sleeve 36, form, therefore make easily because this sliding sleeve 36 separates separately with lid 6.In addition, the part that is formed on the first passage 37 on this sliding sleeve 36 is not all to be formed by square hole, but is formed by square hole 38 and notch 40, owing to shortened the length of part of the formation square hole 38 of difficult manufacturing, therefore makes easily.In addition and since with sliding sleeve 36 and control guiding valve 58 be arranged on piston 32 and piston hole 30 near, therefore, supply from pressure oil to piston hole 30 that can be apace carry out is discharged, and can improve the reactivity that 30 pairs of control guiding valves of piston 58 change.In the above-mentioned existing technical paper, the control guiding valve is set in the guiding valve, needs to adjust the position of control guiding valve and guiding valve, but in the present embodiment, owing to using feedback spring 62, therefore do not need to adjust the position of guiding valve 26 and control guiding valve 58 in order to make control guiding valve 58 revert to the neutral position
As shown in Figure 6, the slide valve for ship use of second mode of execution is by coupling 64 control guiding valve 58 to be contacted with the plunger 66a of ratio electromagnetic coil 66.Because other formation is identical with first mode of execution, so the same section prosign, omits its explanation.
As illustrated in first mode of execution, because the elastic force of feedback spring 62 is set for greater than the mobilization force between control guiding valve 58 and the sliding sleeve 36, therefore, control guiding valve 58 is not connected with the plunger 66a of ratio electromagnetic coil 66, just contact gets final product, and can omit coupling 64, makes easily.
In above-mentioned two kinds of mode of executions, pressure oil is used as pressure fluid, but be not only limited to this, for example also can use pressurized air as pressure fluid.In above-mentioned two kinds of mode of executions, sliding valve hole 68 and piston 70 are used as augmentor, but be not only limited to this, also can use for example with the elastomer of guiding valve 26 to the extruding of lid 6 one sides.In addition, in above-mentioned two kinds of mode of executions, by the electromagnetic type drive portion move control guiding valve after, used feedback spring 62 in order to revert to the neutral position, but be not limited only to feedback spring 62, for example can using, the electromagnetic type drive portion reverts to the neutral position.In above-mentioned two kinds of mode of executions, the ratio electromagnetic coil is used as the electromagnetic type drive portion, but be not only limited to this, also can use for example linear motor.
Because the slide valve for ship use of the 3rd mode of execution of the present invention is to drive following actuator respectively, promptly, therefore as shown in Figure 7, has valve body 102 for example to the pump (not having diagram) of the internal-combustion engine fueling of ship with from the outlet valve of I. C. engine exhaust.Valve body 102 has tube 104.The both ends open of this tube 104, these two ends are respectively by lid 106,108 sealings.
In the inside of this tube 104, vertical along it, for example on the axis of tube 104, sliding valve hole 110 is along its vertical formation.This sliding valve hole 110 forms for example circle hole shape.Be partial on the position of lid 108 1 sides in vertical central authorities, be formed with annular slot 112 towards foreign side's enlarged from this sliding valve hole 110.This annular slot 112 is connected with fuel feed pump by being formed on the fuel supply actuator mouth 114 on the tube 104.Form annular slot 116 in position from these annular slot 112 deflection lids 106 sides.This annular slot 116 is connected with the pressure source of for example pressure oil pump by the pumping hole 118 that is formed on the tube 104.Form annular slot 120 in position from these annular slot 116 deflection lids 108 1 sides.This annular slot 120 is connected with actuator with exhaust by being formed on the exhaust actuator mouth 122 on the tube 104.Promptly be formed with annular slot 112,120 in the both sides of annular slot 116.From the position of these annular slot 120 deflection lids 106 1 sides and on the position of being partial to lids 108 1 sides from this annular slot 112, forming annular slot 124a, 124b respectively.These annular slots 124a, 124b are connected with fuel tank (not having diagram) by reservoir port 125a, the 125b that is formed on the tube 104.Though be provided with two reservoir port 125a, 125b, also can in tube 104, form the fluid passage that connects annular slot 124a, 124b, can only form the side of reservoir port 125a, 125b.
Guiding valve 126 is interted on sliding valve hole 110.It is consistent with the axis of sliding valve hole 110 that guiding valve 126 is that its axis is configured to, and can form slidably along the axial direction of sliding valve hole 110.On the two end part and central part of this guiding valve 126, form valve body 126a, 126b, 126c along the compartment of terrain of vertically leaving of guiding valve 126.This valve body 126a, 126b, 126c are formed on the bulge, and this bulge is in order to seal each annular slot 112,116,120,124a, 124b, and that diameter is expanded with the diameter of sliding valve hole 110 is roughly the same.The diameter of part is less than the diameter of sliding valve hole 10 between these valve bodies 126a, 126b, the 126c.
Fig. 7 represents following state, and promptly valve body 126a is communicated with annular slot 124b and annular slot 112; Though valve body 126b makes annular slot 112 and annular slot 116 sealings, annular slot 116 and annular slot 120 are communicated with; Valve body 126c makes annular slot 124a sealing.Under this state, for example the pressure fluid of pressure oil is discharged to fuel tank from fuel feed pump, and carries out the supply of pressure oil to outlet valve.By position along vertical conversion guiding valve 126 of guiding valve 126, open state by conversion annular slot 116, the pressure oil mass of supplying with to outlet valve can be adjusted,, the pressure oil mass of discharging can be adjusted from fuel feed pump equally by the open state of conversion annular slot 124b.
Shown in Figure 8 is guiding valve 126 is from the state of Fig. 7 state to lid 106 1 side shiftings.Under this state, annular slot 116, is stopped to annular slot 112,120 supply pressure oil by complete closed by valve body 126b.Therefore, do not carry out the supply of pressure oil to fuel feed pump and outlet valve.And, compare with Fig. 7, though that open state becomes is narrow and small, valve body 126a is communicated with annular slot 112 and annular slot 124b, continues from the supply of fuel feed pump to the pressure oil of fuel tank.And valve body 126c removes the sealing of annular slot 124b, and annular slot 120 and annular slot 124a are communicated with.Therefore, pressure oil is discharged to fuel tank from outlet valve.
Shown in Figure 9 is the state that guiding valve 126 is further slided to lid 106 sides from state shown in Figure 8.Under this state, annular slot 124b is by valve body 126a complete closed.Therefore, the discharge of the pressure oil that carries out from fuel feed pump stops.And the sealing of the annular slot 116 that forms by valve body 126b continues.Therefore, do not carry out the supply of pressure oil to fuel feed pump and outlet valve.And, because the opening degree that valve body 126c makes annular slot 124a is greater than state shown in Figure 8, therefore, pressure oil from the discharge capacity of outlet valve more than state shown in Figure 8.Under this state, by the position of conversion guiding valve 126, the open state of reservoir port 124a is changed, can adjust the pressure oil mass of discharging to fuel tank from outlet valve.

And drain boles 274a, the 274b of the first and second control guiding valve 250b, 250a are communicated with drain boles 234a, the 234b of valve body 202 by drain passage 276a, 276b.Drain boles 234a, 234b are communicated with drain boles 278a, 278b on being formed on valve body 202.
On this slide valve for ship use, the switching of the switching of the neutral position of guiding valve 228 and fuel supply position, neutral position and exhaust position is carried out by the following method, promptly supply with pilot pressure oil equably, make and balance in power to the two ends of guiding valve 228, or discharge a side pilot pressure oil, make strength unbalanced.By this formation, because pressurized pressure fluid is filled to second pressure chamber, compare with the situation that guiding valve is moved to there not being pressurized pressure chamber's supply pressure fluid, be subjected to the influence of fluid compression or passage length few, can carry out switch motion at high speed.And, because the first and second control device 240b, 240a mainly are arranged on the lid 208,206 as the part of valve body 202, therefore, compare with the situation in being arranged on guiding valve, process easily.In addition, because the switching that the supply that control is pressed is discharged is carried out by the following method, promptly of being separately positioned in two coil springs on the control guiding valve is carried out excitation, and another is carried out degaussing, or carry out degaussing to one, and another is carried out excitation, so the action of control device can be carried out at high speed.
With reference to Figure 18 to Figure 21, describe with regard to the slide valve for ship use of the 7th mode of execution of the present invention.The slide valve for ship use of the 7th mode of execution is compared with the slide valve for ship use of the 6th mode of execution, and the first and second control device 400b, 400a are different with the formation of neutral device 320b, 320a.Other formations are identical with the slide valve for ship use of first mode of execution, so the same section prosign, omit its explanation.
As shown in figure 20, the first control device 400b of this slide valve for ship use is with the axial direction of two first piston hole 420b along guiding valve 228, forms on the bilateral symmetry ground of axis.First piston 440b can be interted slidably on the 420b of first piston hole, forms first 460b of pressure chamber in the behind of first piston 440b, and coil spring 480b is set on first 460b of pressure chamber.First 460b of pressure chamber is communicated with the first mouth 254a of pressure chamber of the first guiding valve 250b by control pressure passageway 256a.The second control device 400a and this first control device 400b similarly constitute.To the composed component of the second control device 400a, the letter at the end of the composed component of the first control device 400b that will be corresponding with it changes a into, omits its explanation.
As shown in figure 19, neutral device 320b has two the 3rd piston hole 322b that are formed on the lid 208.The 3rd piston hole 322b along the axis of guiding valve 228 vertically, relative axis forms symmetrically at its two ends.And, as shown in figure 20, the 3rd piston hole 322b is provided with as follows, be about to the interconnective straight line of first piston hole 420b of the first control device 400b with the interconnective straight line orthogonal of the 3rd piston hole 322b, and the distance from axle to each the second and the 3rd piston hole 322b, 420b is about equally.As shown in figure 19, the top of the 3rd piston hole 322b is in drain boles 234b upper shed.
The 3rd piston 324b is interted respectively on these the 3rd piston holes 322b, and its top contacts with the end of guiding valve 228b.The 3rd 326b of piston chamber is distinguished than the rear portion of the 3rd piston 324b on these the 3rd piston holes 322b more on the part at rear.At the rear portion of the 3rd piston 324b, the first stopper 328b is by integrally formed.These first stoppers 328b can contact with the stepped part of the tip side that is formed on the 3rd 326b of piston chamber.These first stoppers 328b is the moving range of restriction the 3rd piston 324b to sliding valve hole 210 sides, prevents that the 3rd piston 326b from crossing the neutral position guiding valve 228 is squeezed in lid 208 1 sides.The 3rd 326b of piston chamber is squeezed in sliding valve hole 210 1 sides by for example elastic device of coil spring 330b.The 3rd 326b of piston chamber is connected with pumping hole 216 by pump channel 262b as shown in figure 20.Like this, because two the 3rd piston 324b and two first piston 420b are that symmetry axis ground is provided with by the axle with guiding valve 228b, therefore, the power of its radial direction is inoperative on guiding valve 228b.
In lid 206 1 sides neutral device 320a is set too.Because neutral device 320a is identical formation with neutral device 320b, therefore,, omit its explanation to the composed component of the neutral device 320b symbol that the letter at the end of prosign is changed into a.
Neutral device 320a, 320b and the third and fourth piston 324b, 324a have roughly the same compression area.And, pressure oil is by when the first and second control device 400b, 400a supply with, the compression area of the third and fourth piston 324b, 324a is selected, makes the impacting force of the impacting force of the first and second piston 324b, 324a greater than the 4th and the 3rd control room 336a, 336b.And, on the axis of guiding valve 28, forming through hole 500, its two ends are communicated with drain boles 234a, 234b respectively.Like this, during the volume reducing of drain boles 234a, 234b, oil flows out or flows into to drain boles 234a, 234b from draining 278a, 278b, simultaneously because oil flows out by through hole 500 or flows into, therefore, the oil in the time of can reducing guiding valve 28 and move flow through resistance.
Also the slide valve for ship use with the 6th mode of execution is identical for the slide valve for ship use of Gou Chenging like this, by first to the 4th electromagnetic coil 270a, 270b, 272a, 272b are carried out excitation, degaussing, guiding valve 228 can be switched at fuel supply position, drain position.And, from the fuel supply position when reduce the neutral position, in the time of with the first electromagnetic coil 270b degaussing, with the second electromagnetic coil 272b excitation.The first control guiding valve 265b goes out the position from pressure and switches to pressure supply position.Because control is pressed and supplied with to first 460b of pressure chamber, first piston 440b uses the impacting force that equates with the second piston 440a to push down guiding valve 228, therefore, and the impacting force equilibrium of the impacting force of first piston 440b and the second piston 440a.Therefore, guiding valve 228 passes through the impacting force of the 3rd piston 324b to the neutral position side shifting.At this moment, because by the second stopper 328a, therefore the 4th piston 324a does not work to guiding valve 228 to mobile being limited of lid 208 1 sides.After guiding valve 228 reverted to the neutral position, guiding valve 228 contacted with the 4th piston 324a, the impacting force equilibrium of the 3rd piston 324b and the 4th piston 324a, and guiding valve 228 is maintained at the neutral position.And, when reduce the neutral position, carry out similarly from exhaust position.
In the slide valve for ship use of present embodiment, because two electromagnetic type electromagnetic coils are used in the switching of a control device, therefore, can carry out the switching of control device at high speed, also can carry out the switching of guiding valve at high speed thereupon.In addition, for the control guiding valve of switch control portion is set near the control device, therefore can shorten to the distance of control device.Switch control portion so more at high speed.And, can use the valve of two positions in order to drive two needed electromagnetic type electromagnetic coils of control device, therefore, can provide slide valve for ship use cheap, that can switch at a high speed.
In the 6th and the 7th above-mentioned mode of execution, as the action mouth, be provided with fuel supply actuator mouth 214 and exhaust actuator mouth 222, either party mouth also can only be set.In this case, do not need guiding valve either party control device and control guiding valve, replace, directly from pumping hole to pressure chamber's supply pressure oil.In addition, in the 6th and the 7th above-mentioned mode of execution, first electromagnetic coil has been used the parts of obtaining two positions by excitation and degaussing, replace, can the usage ratio electromagnetic coil, this ratio electromagnetic coil can make the position of control guiding valve change on the position arbitrarily.In this case, when being connected pumping hole on the fuel actuator mouth,, therefore, can control the fuel injection rate of fuel actuator owing to can at random adjust the connected state of fuel actuator mouth and pumping hole.
