Woolson, executrix, Bloom field Village, Mich., assignmto Packard Motor Car Company, Detroit,'Mich., a corporation of Michigan Application August 29, 1930, Serial No. 478,586 7 Claims. (Cl. 192-8) This invention relates to internal combustion engines and more particularly to mechanism controlling the fuel explosive charges delivered to engine combustion chambers.
It isthe general object of the present invention to provide a novel and improved anti-creep device for maintaining a common regulator, fon a plurality of engine fuel injection devices, in any desired position of its adjustment.
More particularly it is an object of the invention to provide a double clutch anti-creep device for the actuating mechanism of a regulator with which a plurality of fuel injection devices of an internal combustion engine are associated.
Still another object of the invention. is to provide an anti-creep mechanism which is associated with a manually actuated element for regulating mechanism controlling the quantity of fuel injected by a plurality of injection devices associated with a multi-cylinder engine.
Other objects of the invention will appear from the following description taken in connection with the. drawings, which form a part of this specification; and in which:
Fig. 1 is a rear elevation view of a radial Diesel engine, partially broken away and in section to illustrate'the fuel control mechanism;
Fig. 2 is a fragmentary sectional view of one ofthe fuel injection devices;
Fig. 3 isan elevational view rearwardly of the engine showing the regulator actuating mechanism and the anti-creep device associated therewith;
Fig.'4 is a sectional view taken on line 4-4 of Fig. 3;
Fig. 5 is a sectional view taken on line 5-5 of Fig. 4. s
Referring to the drawings by characters of reference, 10 is the crank case of an internal combustion engine having a rear cover -11 secured thereto and a.'diaphragm 12 traversing the interior thereof. A plurality of cylinders 13 extend radially from the crank case,-and a pair of compression bands 14 are arranged on two sides of the cylinders and overlap flanges, as
illustrated .at 15, extending therefrom to secure the same against the periphery of the crank case. A piston, as illustrated M16. is arranged to reciprocate within each of the cylinders. and conventional connecting rod means is provided to connect the pistons with the crank shaft 17 which extends axially through the crank case. A single port 18 extends through the head of each cylinder for the intake of air and the discharge of exhaust, a valve 19 being associated with each of such passages. Springs 20 are arranged to normally maintain the valves in closed position, while power driven mechanisms, indicated at 21, are arranged to open the valves, such mechanisms each extend through housings 22, forming a part of the cylinder head, and casings 23 extending intermediate such housings and the crank case. Such mechanisms can be operated through any suitable drive associated with the crank shaft or some driven part of the engine. The engine illustrated is particularly designed for use as the power plant of an airship and is of the four-cycle Diesel type. The valves are maintained in open position during the exhaust and suction strokes of the pistons and are closed during the explosion and power strokes of the pistons. During the suction stroke,.the air portion of the explosion charge is drawn into j the cylinders, preferably in a manner such that it will rotate, and during the compression stroke charges of liquid fuel a'reinjected into the cylinders at a high pressure and in a finely atomizedcondition so that a combustible mixture will be formed, such mixture being of a character that it will ignite under compressionwithin the cylinders. v
An individual fuel injection device is preferably associated with each cylinder and. actuating mechanism, driven by a common member and regulated by another common member, is associated therewith. The injection device consists of a nozzle section 24 and a pump section 25, such sections being secured together to form a unit which is attached directly to the cylinders by the bolts an end portion which projects through the wall of a cylinder and is formed at its outlet end with The nozzle section includes a casing 27 having a flaring opening 28. A bore extends interiorly of the casing from the flared outletand is adapted to receive the valve member 29 which is normally pressed outwardly by a spring 30, so that the valve head 31 will lie adjacent the flared outlet. In
order to prevent the valve head from seating against the nozzle casing, a stop member 32 is adjustably associated with the outer end of the casing and in this manner the outermost position a of the valve can be regulated as desired; The pump section includes a casing 33 which is, screwed upon a neck portion of the nozzle casing and a barrel 34 is held within the'pump casing by a spacer 35. The bore of the barrel is arranged in communication with the bore in the nozzle and a pair of check valves 36 are provided to preventreturn flow of oil into the pump section from the nozzle section. A plurality of ports 37 extend through the pump casing and the barrel and communicate with the interior of the barrel and with a manifold 38 which is secured around each pump casing in sealed relation thereto, there being a plurality of conduits 39 connecting the adjacent manifolds 38. Fuel oil is introduced under a low pressure by suitable mechanism (not shown) so that the manifolds and conduits are constantly filled with oil during operation of the engine. A plunger 40 reciprocates within each of the barrels, and the movement of such plungers beyond the ports 37 determines the quantity of fuel which is evacuated from the nozzles into the cylinders. When the plungers uncover the ports 37, the bore of the nozzle and. that of the barrel and pump section beyond the ports will be maintained filled with voil because of the pressure in the feeding conduits, and hence the effective injection stroke of the plungers after closing the ports 37 determines the quantity in the liquid fuel charges.
Mechanism is associated with each of the plungers for reciprocating the same so that the fuel oil charges will be injected into the, partially compressed air charges in a desired sequence of time. A guide rod engages each of the plungers and each have associated therewith. an articulated rod 42 which also bears against a rock lever 43 pivotally mounted upon a shaft 44 extending between the diaphragm 12 and the rear cover 11. A cam 45 is driven from the crank shaft 17 by reduction gears 46, 47, 48 and'49, and the cam lobes engage with the rock levers 43 to cause an injection stroke of the rods 42 and 41 and the plunger 40. A coil spring-50 is arranged intermediate each pump casing and pump barrel and bears against the flanged end of the plungersfor normally maintaining'and moving them to a position uncovering'the ports 37 after the cam lobes have moved from beneath the rock levers.
In order to regulate the injection stroke of the plungers, there is provided regulating mechanism which includes a ring 51 rotatably secured against the diaphragm 12 by studs 52, there being slots 53 formed in the ring to permit such rotation. A link 54 is pivotally connected to each of the rods 42 and to the regulating ring so that rotation of the ring will move the rods 42 laterally and will vary the length of the injection stroke of the plungers as may be desired. The rock levers43 are formed with a curved surface at their free end upon which the sections 42 of the push rods are adjustable longitudinally of the slippers when the ring 51 is rotated. As the action of' the slippers is the same at all times, the adjustment of the position of the push rod sections on the curved surfaces will vary the stroke of the push rods relative to the ports 37 and willalso vary the time at which they will close the ports. It will be understood that this ring regulator can be adjusted so that the plunger stroke can be regulated in agiven range after closing the ports and thus the desired quantity in the fuel devices can be obtained, or the adjustment can be such that upon the injection stroke of the plunger the ports 37 will not be closed and under such circumstances the engine will cease operating.
Suitable mechanism is provided for the rotation of the regulating ring 51. It will be observed that the springs 50 exert a force against the plungers and the rods 41 and 42 tending to move the regulating ring .51 in a clockwise direction, looking at the rear of the engine, which reduces the length of the plunger injection strokes, and thiscreeping condition is accentuated by any vibration of the engine. This tendency to change the ring position is undesirable because of the reduction in the quantity of fuel charges which will become less and less and finally stopthe engine, and in order to maintain the ring 51 in any position of adjustment and at the same. time impose no force rearwardly from the engine to the cockpit of the.
airship in which the engine is mounted. A
bracket is fixed to a strut 61 of the airplane fuselage and operating mechanism, including a hand lever 62, a lever 63 and a clutch device intermediate such levers, is arranged so that it will reciprocate the extension rod 59. A bearing plate 64 is arranged adjacent the upper end of the bracket 60 and a stationary race member 65 is secured against the bearing plate and to the bracket by means of screws 66. The fixed outer race 65 is formed upon a; shaft 6'1 and includes a peripheral flange 68 forming a housing for the inner race 69 of the clutch device and for the actuating member '70 whichis secured to the hand lever 62 by rivets 71. The inner race is provided with an elongated hub 72 with which a carrier 73 is fixed to rotate by the key 74, such carrier bein welded to the lever 63, or secured thereto in some other suitable manner. A nut75 is screwed upon the hub '72 against a washer 76 for securing the carrier '13 axially upon the hub of the inner race member. Nuts 77 are screwed upon the ends of the shaft 67 to secure the inner race axially upon the shaft to assist in retaining the outer race with the fixed bracket 60. As before stated, the fixed race forms a housing for the inner race and for the actuating portion of the member 70. The inner race is provided with a plurality of spaced recesses in its periphery into each of which an arm '18 of the actuator member extends. Balls 90 are arranged in such recesses upon opposite ends of the arms, and bearings 79 urge the balls against the arms of the actuating member through pressure of coil springs 80 which are seated in recess extensions. The bottom of the recesses are disposed at an angle relative to the surrounding annular surface of the outer race member and the balls are of such diameter that they will wedge intermediate such adjacent faces of the race members, and thereby prevent any relative movement thereof. It will be seen that one of. the balls in' each recess will wedge be tween the race members upon a relative movement in either direction.
The lever 62 is mounted to rotate upon carrier member '73, while the actuator section 70 thereof telescopes a hub portion of the inner race member and is rotatable thereon. movement of the lever 62 in either directzi 2 will move the actuator section 70 therewith and the arms 78 will unwedg'e the balls tending to impede movement of the inner movable race in the direction of the lever movement. The arms '78 will move such balls and release them from wedged -the angular surfaces 81 are arranged so that the ber, it being obvious that the balls on the opposite sides of the arms 78 will not impede such movement. Rotation of the inner race, in. this'manner, is transmitted to the carrier'13 because of the keyed connection 74 and likewise to the lever 63 which is welded to the carrier, and such movement of the lever 63 is transmitted to actuate the rod 59 which in turn will rotate the shaft 57 and cause the gear segment 56 to rotate the regulator ring 51. The clutch device becomes automatically effective to prevent relative movement 'of the race members when application of force against the lever 62 ceases and at the same time offers little impediment to the manual operation of the lever. With the control mechanism described, the regulating ring 51 can be readily rotated,- as may be desired; and will be locked in any position 'of adjustment within its range of movement. Movement of the ring counter-clockwise, as viewed in Fig. 1, will move the push rod sections "12 toward the free end of the slippers and-adjustment in this direction increases the distance that the plungers are moved after closing the ports 3'7, thereby increasing the quantity of the fuel charges delivered. Movement of the ring in a clockwise direction shifts the inner end of thepush rod sections 42 toward the pivoted end of the slippers and adjustment in this direction lessens the stroke of the plungers after closing the ports-37 except at the extreme end ofsuch adjustment whereupon the plungers in their movement will not close the ports and thus there will be no fuel delivered.
