Abstract: The present invention relates to a reciprocating compressor. The reciprocating compressor includes a latching unit by which a piston is reciprocated by two times a total eccentric amount obtained by adding an eccentric amount of an eccentric portion to an eccentric amount of an eccentric sleeve in a power mode, while the piston is reciprocated by two times the eccentric amount of the eccentric portion in a saving mode, accordingly the piston can have an upper dead point same in the power mode and the saving mode, thereby reducing a dead volume between the piston and a discharge valve and increasing a variable ratio of a cooling capacity of the compressor in the saving mode.

Abstract: A variable displacement reciprocating pump with pumping rate that is adjustable from zero to maximum stroke while the pump is running. Stroke is varied by changing relative position of pairs of eccentric inner and outer cams that drive the pump's plungers. The pump's input drive shaft drives two gear trains: a first gear train that turns the inner cams and a second gear train that turns the outer cams. These cams normally revolve together with no relative motion occurring between them. A rotary actuator is positioned in the first gear train to rotate the inner cams relative to the outer cams and thereby changes the pump's stroke. A computerized system of sensors and control valves allows the pump to be automatically controlled or limited to any one or combination of desired output flow, pressure and horsepower.

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 multi-cylinder compressor 10 particularly useful in connection with northern climate heat pumps and in which different capacities are available in accordance with reversing motor 16 rotation is provided with an eccentric cam 38 on a crank pin 34 under a fraction of the connecting rods, and arranged for rotation upon the crank pin between opposite positions 180.degree. apart so that with cam rotation on the crank pin such that the crank throw is at its normal maximum value all pistons pump at full capacity, and with rotation of the crank shaft in the opposite direction the cam moves to a circumferential position on the crank pin such that the overall crank throw is zero. Pistons 24 whose connecting rods 30 ride on a crank pin 36 without a cam pump their normal rate with either crank rotational direction. Thus a small clearance volume is provided for any piston that moves when in either capacity mode of operation.
