    摘要: A scroll-type compressor is disclosed which includes both a high pressure lubricant sump and a low pressure lubricant sump. Lubricant from the low pressure lubricant sump is supplied to the various bearing, thrust surfaces and other moving parts to lubricate same and a portion thereof is also supplied to the suction gas entering the compressor to replenish the lubricant in the high pressure sump. An oil separator is disposed in a discharge chamber to separate entrained oil from the compressed gas. A level control assembly is also provided in the discharge chamber and serves to return excessive accumulations of oil from the high pressure sump to the low pressure sump. In one embodiment, the compressor is specifically designed for compression of helium while in a second embodiment, the compressor is adapted for use as an air compressor.

    摘要: A pulsed modulated capacity modulation system for refrigeration, air conditioning or other types of compressors is disclosed in which suitable valving is provided which operates to cyclically block flow of suction gas to a compressor. A control system is provided which is adapted to control both the frequency of cycling as well as the relative duration of the on and off time periods of each cycle in accordance with sensed system operating conditions so as to maximize the efficiency of the system. Preferably the cycle time will be substantially less than the time constant of the load and will enable substantially continuously variable capacity modulation from substantially zero capacity to the full capacity of the compressor. Additional controls may be incorporated to modify one or more of the motor operating parameters to improve the efficiency of the motor during periods of reduced load.

    摘要: An electrical motor driven rotary compressor having electrical components for preventing reverse rotation of the motor-compressor upon deenergization of the motor. The rotary compressor determines if a change in condition has occurred which could result in reverse rotation of the motor-compressor and energizes a motor stator circuit in response to the determined change in condition so as to apply a braking torque to oppose reverse rotation of the motor-compressor.

    摘要: A flash tank for a heat pump operable in a heating mode and a cooling mode includes a shell having a middle portion disposed between a top portion and a bottom portion, with the top portion, bottom portion, and middle portion cooperating to define an inner volume of the shell. A first port is in fluid communication with the inner volume and functions as an inlet in the heating mode and as an outlet in the cooling mode. A second port is in fluid communication with the inner volume and functions as an inlet in the cooling mode and as an outlet in the heating mode. Flow control devices and check valves are fluidly coupled to control the tank as a flash tank in heating mode and as a receiver in cooling mode.
