摘要： A two-stage reciprocating compressor is provided. The compressor includes a block with a single cylinder and associated single compression chamber and single piston. The compressor further includes a crankshaft. The crankshaft has an eccentric crankpin that is operatively connected to the piston. A reversible motor is provided to rotate the crankshaft in a forward direction and in a reverse direction. An eccentric cam is rotatably mounted on the eccentric crankpin. The eccentric cam is held stationary with respect to the crankpin when the crankshaft is rotating in the forward direction. When rotating in the forward direction, the crankshaft drives the piston at a full stroke between a bottom position and a top dead center position. The eccentric cam rotates with respect to the crankpin when the crankshaft is rotating in the reverse direction. When rotating in the reverse direction, the crankshaft drives the piston at a reduced stroke between an intermediate position and the top dead center position.

摘要： A high side co-rotating refrigerant scroll compressor includes a motor disposed vertically above its compression mechanism. The discharge of gas from the compression mechanism is through the drive shaft of the drive scroll member which is rotatably supported at its distal end in an upper bearing. Upper bearing lubrication is accomplished by the disentrainment of oil from the mixture of compressed refrigerant gas and oil discharged from the compression mechanism in the vicinity of the bearing and by the direction of such disentrained oil to the bearing.

摘要： A two-stage reciprocating compressor is provided. The compressor includes a reversible motor that rotates a crankshaft. The crankshaft is connected to a piston by a mechanical system. The mechanical system drives the piston at a full stroke between a bottom position and a top dead center position when the motor is operated in a forward direction. The mechanical system drives the piston at a reduced stroke between an intermediate position and the top dead center position when the motor is operated in the reverse direction. The compressor also includes a control for selectively operating the motor in either the forward direction at a first preselected, fixed speed or in the reverse direction at a second preselected fixed speed.

摘要： A scroll-type refrigeration compressor has a gas-liquid mixture discharge passage extending through the driver scroll drive shaft for discharging refrigerant gas and entrained lubricant into a high pressure chamber in the compressor housing. An anti-reverse rotation valve is connected to the distal end of the drive shaft and includes a valve housing with radially extending discharge ports and a closure member movable to prevent reverse flow of high pressure gas to the scroll compression chambers to prevent reverse rotation on compressor shutdown. A pressure equalization port may be formed in the valve closure member, valve housing or the distal end of the drive shaft to allow slow bleed down of pressure from the high pressure side to the low pressure side to minimize starting torque of the drive motor. The valve may be formed from a tubular metal housing and having a plug-type closure member slidably disposed therein with the housing being press fitted in a counterbore in the end of the shaft. A gas-liquid separation baffle may be disposed around the valve housing for assisting in gas-liquid separation after the mixture is discharged from the valve housing. Valve embodiments include a housing and closure member arrangement supported such that rotation of the drive shaft exerts a centrifugal force on the closure member to bias it toward an open position. Centrifugal force responsive valves may be moved to their closed position by a biasing spring, pressure forces and gravity forces acting thereon, respectively.
