摘要： The invention provides a servo valve with a main piston and a servo piston. The servo piston controls a pressure in a servo chamber and thereby controls movement of the main piston based on a pressure difference between two chambers of the valve. To facilitate opening of the valve by relatively small pressures even in high pressure systems, the servo chamber according to the invention is provided inside the armature.

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： At least one bypass opening is formed in a base of a scroll member, and communicates with at least one compression chamber. The bypass opening communicates with a passage leading to a suction pressure chamber within a compressor shell. A valve includes an element electrically powered to move between a first position at which it blocks flow of refrigerant from the bypass port to the passage leading to the suction pressure chamber, and a second position at which it allows flow of refrigerant between the bypass port and the passage leading to the suction pressure chamber. A portion of the valve, which is electrically powered, is mounted outside of the compressor shell.
