Embodiment
Below, at length describe based on the mode of execution of accompanying drawing the optimum of the utility model.In addition, as long as in following explanation, there is not the special meaning that limits the scope of the utility model of record, the scope of the utility model just is not limited to these modes.
In addition, in this manual, the direction of extending with the body shell 111 of main valve 11 is an X-axis direction, and the direction of extending with each joint is a Y direction, is that Z-direction describes with the direction vertical with X axle and Y axle.
(first mode of execution)
With reference to Fig. 1 and Fig. 2 the four-way valve 100 of first mode of execution is described.Fig. 1 is the plan view of the four-way valve 100 of first mode of execution, and Fig. 2 is the side view of the four-way valve 100 of first mode of execution.
Fig. 1 and four-way valve 100 shown in Figure 2 comprise: the main valve that turns to 11 that carries out fluid; And uprightly in its bottom surface be located on the main valve 11 and as the control valve 10 of controlling the electromagnetic drive part that turns to of the fluid in the main valve 11 by means of switching on.
Though not shown, control valve 10 also possesses the valve seat of folding and unfolding in drive portion main body 101, valve body, plunger etc. except drive portion main body 101.Concrete structure has been documented in the applicant's the TOHKEMY 2011-117528 communique.
In the outside of drive portion main body the electromagnetic coil that is used for drive control valve is installed, this electromagnetic coil possesses permanent magnet.Therefore, even, also can utilize the adsorption force of this permanent magnet itself to make attractor and plunger keep adsorbed state after making plunger absorption attractor, stopping energising to electromagnetic coil to the electromagnetic coil energising.Thus, only need the short time that plunger adsorbs attractor is reliably got final product, therefore can suppress the rising of coil temperature to the time of electromagnetic coil energising.
As shown in Figure 1, main valve 11 comprises: to the body shell 111 of X-axis direction extension; Be arranged on this body shell 111+Y side and inject the high pressure joint DP of high-pressure liquid; And be arranged on body shell 111-three joints of Y side, the i.e. first steering knuckle EP, low-pressure connector SP and the second steering knuckle CP.At this, on X-axis direction, low-pressure connector SP is configured in centre, disposes the first steering knuckle EP and the second steering knuckle CP in its both sides.
In addition, be used at four-way valve 100 under the situation of air-conditioning etc., for example, the first steering knuckle EP is connected with the indoor set EM (with reference to Fig. 3) of air-conditioning, and the second steering knuckle CP is connected with outdoor unit CM (with reference to Fig. 3).
In addition, on control valve 10, be provided with: the high pressure capillary DC that links drive portion main body 101 and high pressure joint DP; The low pressure capillary tube SC that links drive portion main body 101 and low-pressure connector SP; And first the turning to turn to and use capillary tube C2 of the P1 of piston chamber, P2 (with reference to Fig. 3) that links the two end part of drive portion main body 101 and body shell 111 with capillary tube C1 and second.
In this mode of execution, main valve 11 is configured on the XY plane, and control valve 10 disposes with the central shaft of drive portion main body 101 mode parallel with the Z axle.That is, control valve 10 is configured to vertical with body shell 111, high pressure joint DP, low-pressure connector SP, the first steering knuckle EP and the second steering knuckle CP of main valve 11.
Below, with reference to Fig. 3 the runner of four-way valve 100 is turned to describe.Fig. 3 is the skeleton diagram that is used to explain that the runner of the four-way valve 100 of first mode of execution turns to.In Fig. 3,, indoor set EM and outdoor unit CM have therefore been appended owing to being that an example describes with air-conditioning.
As shown in Figure 3, for example, not under the situation of control valve 10 energisings, plunger is pressed by means of the elastic force in the control valve 10, links thereby low pressure capillary tube SC and first is turned to capillary tube C1.At this moment, because second turn to the binding with capillary tube C2 and high pressure joint CP, so body shell 111 interior slide-valves 112 move to the direction shown in the arrow A R.Thus, the low-pressure connector SP and the first steering knuckle EP are linked.
Fluid in the four-way valve 100 constitutes the runner that returns high pressure joint DP from high pressure joint DP successively through the second steering knuckle CP, outdoor unit CM, indoor set EM, the first steering knuckle EP, low-pressure connector SP and compressor CD in this case.
On the contrary, though not shown, under the situation of control valve 10 energisings, low pressure capillary tube SC and second is turned to capillary tube C2 link.At this moment, because first turn to the binding with capillary tube C1 and high pressure joint DP, so body shell 111 interior slide-valves 112 move to the opposite direction of arrow A R.Thus, the low-pressure connector SP and the second steering knuckle CP are linked.Fluid in the four-way valve 100 constitutes the runner that returns high pressure joint DP from high pressure joint DP successively through the first steering knuckle EP, indoor set EM, outdoor unit CM, the second steering knuckle CP, low-pressure connector SP and compressor CD in this case.
(second mode of execution)
With reference to Fig. 4 and Fig. 5 the four-way valve 200 of second mode of execution is described.Fig. 4 is the plan view of the four-way valve 200 of second mode of execution, and Fig. 5 is the side view of the four-way valve 200 of second mode of execution.In second mode of execution, enclose identical symbol in the constituting component identical and describe with first mode of execution.
Like Fig. 4 and shown in Figure 5, to compare with first mode of execution, the control valve 20 of second mode of execution does not have the high pressure capillary (with reference to Fig. 1 and Fig. 2) that is connected with high pressure joint DP.
Alternatively, form the through hole of body shell 211 of drive portion main body 201 and the main valve 21 of hitch control valve 20 at position that control valve 20 combines with main valve 21.
That is, as shown in Figure 6, in four-way valve 200, high pressure joint DP links by means of through hole TH and drive portion main body 201, and this through hole TH plays the effect of the high pressure capillary DC illustrated in fig. 3 of first mode of execution.According to this structure, can reduce the quantity capillaceous of four-way valve 200, make its structure simpler.
In addition, four-way valve 200 is configured with plane in this mode of execution.That is, main valve 21 and control valve 20 all are configured on the XY plane.Thus, can on Z-direction, compress four-way valve 200.
(the 3rd mode of execution)
With reference to Fig. 7 and Fig. 8 the four-way valve 300 of the 3rd mode of execution is described.Fig. 7 is the plan view of the four-way valve 300 of the 3rd mode of execution, and Fig. 8 is the side view of the four-way valve 300 of the 3rd mode of execution.In the 3rd mode of execution, enclose identical symbol in the constituting component identical and describe with first mode of execution.
In the 3rd mode of execution, main valve 31 is configured on the XY plane, and control valve 30 disposes (with reference to first mode of execution) with the central shaft of drive portion main body 301 mode parallel with the Z axle.In addition, four-way valve 300 connects control valve 30 and main valve 31 through through hole TH, becomes the structure (with reference to second mode of execution) that does not need high pressure capillary thus.
In above first mode of execution to the, three mode of executions; Though the electromagnetic coil through possessing permanent magnet comes drive control valve; But also can be the electromagnetic coil of being put down in writing like the applicant's TOHKEMY 2011-117528 communique, that is, not possess the electromagnetic coil of permanent magnet.
More than,, know that the utility model can be in its technical scope carries out various changes, distortion to mode of execution and implements though the mode of execution of the optimum of the utility model at length is illustrated according to those skilled in the art.
