Abstract: A scroll compressor (10) with a fixed scroll (18) and orbital scroll (20) has an axial thrust and anti-rotation assembly (22), a drive assembly (24), a balance assembly (26) and a control system (28). The drive assembly (24) includes a crankshaft (116) and a bushing assembly (108). The bushing assembly includes a bushing body (146) with a slot (154) journaled on the orbital scroll and a drive lug (150) positioned in the slot and non-rotatably secured to the crankshaft. Springs (156) bias the bushing body toward a position in which the axis of the bushing body (178) coincides with the axis (176) of the crankshaft (116) and the crankshaft can rotate without moving the orbital scroll (20). The bushing body can be moved by compressed fluid to a position in which the springs are compressed, the scroll wraps (34 and 56) are in sealing contact and the drive assembly will drive the orbital scroll (20) in a circular orbit with a radius R.sub.o. The balance assembly includes two weight assemblies (184 and 186) with four weights (192, 196, 210 and 214) that are rotated about the axis of cylindrical extension (182) in response to movement of the drive lug (150) relative to the bushing body (146) between a position in which the orbital scroll is balanced and a position in which the weights balance themselves when the crankshaft rotates without driving the orbital scroll. The control system includes a trigger compressor (242) and a solenoid valve (246) which directs compressed fluid to the sump (88) when the valve is open and to the chamber (162) in the bushing assembly when the valve is closed.

Abstract: A wobble plate compressor which is adapted to vary the angularity of the wobble plate during rotation in response to the difference between the resultant reaction force exerted by the pistons on their compression and suction strokes and the pressure in the crankcase. The wobble plate is supported by a first fulcrum movable along the drive shaft around which it is disposed, at a diametrically central location, and by a second fulcrum at a location radially spaced from the drive shaft. The second fulcrum is formed by an end of an arm member disposed for rotation together with the drive shaft. The above end of the arm member is in camming engagement with a side surface of the wobble plate so that with an increase in the angularity of the wobble plate the second fulcrum moves toward the axis of the drive shaft through a substantial stroke, whereby the angularity of the wobble plate can vary at a reduced rate relative to a change in the pressure in the crankcase, thereby enhancing the stability of capacity control.

Abstract: A compressor assembly for pumping a recirculating refrigerant including a power input shaft, a power output shaft and a clutch disposed therebetween for translating torque from the power input shaft to the power output shaft. The clutch includes a solenoid for generating an electromagnetic force and an actuator including input friction plates mounted for rotation with the input shaft and output friction plates mounted for rotation with the output shaft. The input and output friction plates are adapted for frictional engagement to translate torque between the input and output shafts. The actuator is responsive to the electromagnetic force to initially move along the axis of the input shaft thereby bringing the input and output friction plates into engagement to translate torque between the input and output shafts to actuate the compressor assembly so as to produce a refrigerant discharge pressure. The actuator is further responsive to the discharge pressure to develop a greater force between the input and output friction plates thereby bringing about full torque translation between the input and output shafts.

Abstract: An assembly for providing socket plate torque restraint for a variable displacement wobble plate refrigerant compressor includes a non-rotary cross groove joint. The joint has a cylindrical outer race, a cylindrical inner race, slightly angled helical grooves in the races, a plurality of torque receiving balls and a cage for properly maintaining and positioning the balls in the cooperating grooves for operation. The joint is connected to a fixed anti-rotational shaft. The shaft is in the form of a sleeve and forms the inner race to effect torque restraint, but at the same time allow for translational axial motion of the socket plate. Radial and thrust bearings mount said socket plate relative to the rotary hub/journal. Lubricating fluid carried by the gaseous refrigerant lubricates the grooves and is then transferred by a passage extending from the grooves in the outer race to the radial/thrust bearings. The cross groove joint provides the ideal kinematic restraint action for the socket plate; the grooves on said inner and outer races and said cage effectively maintaining the balls situated substantially in a single torque transmitting plane that defines and bisects the joint angle. The joint effectively transmits the restraining torque of the joint to the anti-rotational shaft in a manner effective to substantially eliminate torsional vibration.

Abstract: A wobble plate compressor which is adapted to vary the angularity of the wobble plate during rotation in response to the difference between the resultant reaction force exerted by the pistons on their compression and suction strokes and the pressure in the crankcase. The compressor has a passage with an orifice communicating a lower pressure space therein with the interior of the crankcase, a communication passage communicating a higher pressure space therein with the interior of the crankcase, and a control valve means for controlling the opening of the communication passage. Preferably, the cross-sectional area of the above orifice passage is set at such a value as to permit blow-by gas leaking from the cylinders into the crankcase to escape from the crankcase into the lower pressure space at a flow rate at least equal to the maximum possible flow rate at which the blow-by gas leaks from the cylinders into the crankcase.
