Abstract: A two stage reciprocating compressor and associated HVAC systems and methods are disclosed. The reciprocating compressor includes a crankshaft having an eccentric crankpin, a reversible motor for rotating the crankshaft in a forward and a reverse direction, and an eccentric, two position cam rotatably mounted over the crankpin. The crankshaft and cam combine to cause the piston to have a first stroke when the motor operates in the forward direction and a second stroke when the motor operates in the reverse direction. The cam and crankpin also include stabilization means to restrict the relative rotation of the cam about the crankpin. A lubrication system is provided to lubricate the engaging surfaces of the crankshaft and cam and between the cam and the bearing surface of the connecting rod. There is also provided a control for selectively operating the motor either in the forward direction at a first power load or in the reverse direction at a reduced second power load. A protector for the motor is also provided. In addition, the application of the reciprocating compressor to both air conditioning and heat pump systems is disclosed.

Abstract: A stabilizing structure for a throw adjusting eccentric cam in a two-stage reciprocating compressor is provided. The compressor includes a block that has at least one cylinder with an associated compression chamber and piston, a crankshaft that includes an eccentric crankpin, and a reversible motor for rotating the crankshaft in a forward and a reverse direction. An eccentric, two position cam is rotatably mounted over the crankpin. The cam rotates to and operates at a first position relative to said crankpin when the motor is running in the forward direction and rotates to and operates at a second position relative to said crankpin when the motor is running in the reverse direction. The combined eccentricities of the crankpin and the cam cause the piston to have a first stroke when the motor operates in the forward direction and a second stroke when the motor operates in the reverse direction. There is also provided a control for selectively operating the motor either in the forward direction or in the reverse direction.
