    摘要： A scroll compressor comprises a first scroll member having a generally spiral wrap and a second scroll member having a generally spiral wrap. The generally spiral wraps interfit to define compression chambers. A pair of ports leads from the compression chambers. A pair of valves selectively blocks flow of refrigerant from the ports leaving the compression chambers. The valves selectively control the flow such that flow may pass from neither of the two ports, from both of the two ports, or from only one of the two ports to provide three levels of capacity control.

    摘要： A scroll compressor includes a compressor shell having first and second scroll members. The scroll members each have a base and a generally spiral wrap extending from its base. The generally spiral wraps of the first and second scroll members interfit to define compression chambers. A shaft causes the second scroll member to orbit relative to the first scroll member. At least one bypass port is formed in a base of one scroll member, and communicates with at least one of the compression chambers. The bypass port communicates with a passage leading to a suction pressure chamber within the compressor shell. A solenoid valve is movable between a reduced capacity position and a full capacity position, and selectively supplies a pressurized fluid to a fluid valve associated with the bypass port, such that movement of the solenoid can control whether the bypass port is open or closed.

    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.

The valve spool will be driven to a second position at which it blocks communication for oil return.
