摘要： A multi-stage compressor having a shaft with two eccentrics that are offset with respect to the shaft axis of rotation in substantially the same radial direction, compressor also having two vanes oriented in substantially opposite radial directions with respect to shaft axis. Also, a multi-stage compressor having a first-stage cylinder for compressing a fluid, e.g., a refrigerant, from a low pressure to an intermediate pressure, a second-stage cylinder for compressing the refrigerant from the intermediate pressure to a high pressure, and a housing having an intermediate-pressure refrigerant outlet in direct fluid communication with the first-stage cylinder and an intermediate-pressure refrigerant return inlet in fluid communication with the interior of the compressor housing. Also, a compressor having a vane operably engaged with a shaft eccentric and a spring biasing the vane toward the eccentric, wherein the amount of biasing force applied by the spring is adjustable.

摘要： A refrigeration system for freezing fluid in a tray during a first operating mode and defrosting the ice during a second operating mode to facilitate the removal of the ice from the tray. In the first operating mode, refrigerant circulates through a circuit in a first direction and, in the second mode, the flow of refrigerant is reversed in a portion of the circuit. In the first operating mode, cool refrigerant exits an expansion device in the circuit and enters into the evaporator to freeze a fluid in the tray. In the second operating mode, a valve is operated to permit warm refrigerant exiting the compressor to enter into the evaporator to melt a portion of the ice reversing the flow of refrigerant therein. A second valve permits the reverse flow of refrigerant through the evaporator to return to the compressor inlet instead of passing through the expansion device and condenser.
摘要翻译：一种用于在第一操作模式期间冷冻托盘中的流体并在第二操作模式期间对冰进行除霜以便于从托盘移除冰的冷冻系统。在第一操作模式中，制冷剂在第一方向上循环通过电路，并且在第二模式中，制冷剂的流动在电路的一部分中反转。在第一操作模式中，冷却的制冷剂从电路中的膨胀装置排出并进入蒸发器以冻结托盘中的流体。在第二操作模式中，阀被操作以允许从制冷剂排出的温暖的制冷剂进入蒸发器以熔化反向其内的制冷剂流的一部分冰。第二个阀允许制冷剂通过蒸发器的反向流动返回到压缩机入口，而不是通过膨胀装置和冷凝器。
