    摘要： A scroll compressor includes structure between an eccentric and a slider block that separates the scroll wraps when the orbiting scroll is driven in a reverse direction by entrapped fluid. In the prior art, entrapped fluid sometimes has driven the orbiting scroll in a reverse direction at shutdown, resulting in undesirable noise. The present invention stops movement of the orbiting scroll relative to the fixed scroll during reverse rotation by opening the fluid chambers dissipating that pressure.

    摘要： 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.

    摘要： A high side co-rotational scroll compressor has lubricant sumps in both the discharge and suction pressure portions of its hermetic shell as well as a pressure biasing arrangement by which the scroll members are urged together in operation to minimize internal leakage. Lubrication of the bearing in which the driven scroll member rotates as well as to the bearing in which the idler scroll member rotates, both of which are located in the suction pressure portion of the shell, is provided for. Additionally, embodiments are taught by which the interface between the tips of the wraps of each scroll member and the end plate of the opposing scroll member are lubricated and by which the seal in the axial pressure biasing arrangement is lubricated and/or shielded from debris having the potential to damage it.

    摘要： A high-side co-rotating refrigerant scroll compressor defines a lubricant sump in its discharge pressure portion. Lubricant is directed from that sump, through a passage which is at least partially defined by the shell of the compressor, to the bearings in which the scroll members rotate. Heat carried in the lubricant flowing through the passage is transferred through the compressor shell to the ambient. Subsequent to having lubricated the bearing in which the drive scroll member rotates, lubricant is diverted into a passage defined by the drive scroll member drive shaft and enters the stream of compressed discharge gas flowing therethrough. The lubricant is thereby prevented from entering the suction pressure portion of the compressor where it would otherwise heat compressor suction gas prior to the entry of that gas into the compressor's compression mechanism.

    摘要： A valve for selectively allowing the return of oil from a discharge plenum to a suction plenum includes a passage which is selectively opened or blocked by a valve spool. The valve spool sees a pressure from a discharge pressure location upstream of a discharge check valve on one face, and a discharge pressure from a discharge plenum on an opposed face. While the compressor is running, the two pressures should be relatively equal. The face which sees the pressure from the chamber upstream of the check valve is larger than the face which sees the pressure from the discharge plenum. Thus, when the compressor is running, the valve spool is biased to a first position at which it allows oil return from the discharge plenum to the suction plenum. However, upon shutdown of the compressor, the pressure in the chamber upstream of the discharge valve drops. The valve spool will be driven to a second position at which it blocks communication for oil return.

    摘要： A valve for selectively allowing the return of oil from a discharge plenum to a suction plenum includes a passage which is selectively opened or blocked by a valve spool. The valve spool sees a pressure from a discharge pressure location upstream of a discharge check valve on one face, and a discharge pressure from a discharge plenum on an opposed face. While the compressor is running, the two pressures should be relatively equal. The face which sees the pressure from the chamber upstream of the check valve is larger than the face which sees the pressure from the discharge plenum. Thus, when the compressor is running, the valve spool is biased to a first position at which it allows oil return from the discharge plenum to the suction plenum. However, upon shutdown of the compressor, the pressure in the chamber upstream of the discharge valve drops. The valve spool will be driven to a second position at which it blocks communication for oil return.
