    摘要： A rotary compressor for compressing a refrigerant gas has a by-pass port and a control valve means. The by-pass port communicates at one end with a suction chamber containing the gas to be compressed, and at the other end with a compression chamber wherein compression of the refrigerant gas is in progress. The control valve means includes a valve spool accommodated in a chamber formed in a front side plate of the compressor and movable between its full-load position, where a gas suction port is opened to the compression chamber while the by-pass port is closed, and its partial-load position where the former is at least partially closed while the latter is opened. The valve spool is normally biased to its partial-load position. During operation of the compressor, the valve spool is placed under the influence of a first pressure of the gas acting to urge the same towards its said full-load position, and to a second pressure of the gas to urge the same towards its said partial-load position. The spool is shifted automatically to its partial-load position when the difference between these first and second pressures is decreased with a drop of cooling load. The compressor of the invention further comprises a flow control means for regulating the flow of the gas into its compression chambers in the event of a rapid increase of compressor speed.

    摘要翻译： 用于压缩制冷剂气体的旋转压缩机具有旁路口和控制阀装置。 旁通口在一端与包含被压缩气体的吸入室连通，另一端与压缩室连通，其中制冷剂气体的压缩正在进行。 控制阀装置包括容纳在形成在压缩机的前侧板中的腔室中的阀芯，并且在旁路口关闭的同时在其满载位置和气体吸入口与压缩室打开的位置之间移动， 以及其部分负载位置，其中前者在打开后至少部分关闭。 阀芯通常被偏压到其部分负载位置。 在压缩机的运行期间，阀芯被放置在气体的第一压力的作用下，以将气体推向其所述满载位置，并且将气体推向其所述部分的第二压力 - 位置。 当这些第一和第二压力之间的差异随着冷却负荷的下降而减小时，阀芯自动转移到其部分负载位置。 本发明的压缩机还包括流量控制装置，用于在压缩机速度快速增加的情况下调节气体流入其压缩室的流量。

The first and the second rotary valves respectively have first and second introduction passages. The distance to the first communication passage from the suction pressure region through the first introduction passage is greater than the distance to the second communication passage from the suction pressure region through the second introduction passage. The first communication passage with a circular cross-section in the cylinder block connects the first compression chamber to the first introduction passage. The second communication passage with a circular cross-section in the cylinder block connects the second compression chamber to the second introduction passage. The diameter of the first communication passage is greater than the diameter of the second communication passage.

    摘要： A refrigerating system for air-conditioning an air-conditioned area, and incorporating therein a variable capacity refrigerant compressor in which the delivery amount of the compressed refrigerant is varied by changing the stroke of the reciprocating pistons which are operatively connected to a swash plate mechanism by changing its angle of inclination in response to a change in the pressure in a crank chamber, a condenser for condensing the compressed gas-phase refrigerant from the compressor, a pressure reducing unit for reducing the pressure of the liquid-phase refrigerant, an evaporator for vaporizing the liquid-phase refrigerant by removing heat from the air, around the evaporator, which cools the air-conditioned area, and a refrigerant supply conduit supplying the crank chamber of the compressor with a part of the liquid-phase refrigerant flowing in a portion of the refrigerant conduit extending from the condenser to the evaporator so that during the minimum capacity operation of the compressor, the compressor is cooled and lubricated by the supplied refrigerant. A flow regulating unit for adjustably regulating the flow of the liquid-phase refrigerant flowing through the refrigerant supply conduit is also arranged.
