    摘要： This invention is directed to a useful improvement in a capacity control valve for use in a fluid compressor with a relatively high pressure HP and a relatively low pressure LP for changing the operational characteristics thereof by using the relatively high pressure HP taking into consideration such an observation that an increased pressure losses of the refrigerant as generated from an increased flow rate thereof and the thermal load on the car cooler would occasionally occur on the part of the relatively high pressure HP during the operation. This improvement is, as summarized in brief, concerned with a capacity control valve of the type operative to take the intermediate pressure AP, for the control of a specific amount of compressed gas to be bypassed to the suction side of the fluid compressor, as a linear function of said relatively low pressure LP using a differential pressure between the relatively high pressure HP and the relatively low pressure LP of the fluid compressor; which comprises an adjusting means adapted to adjust the intermediate pressure AP in such a manner that the relative low pressure LP is made lower as the relatively high pressure HP becomes higher, and that said relatively low pressure LP is made higher as said relatively high pressure HP becomes lower.

    摘要翻译： 本发明涉及一种用于具有较高压力的流体压缩机的容量控制阀以及相对低压的LP，用于通过使用相对高压的HP考虑这种观察来改变其操作特性 在运行期间，相对高压的HP部分将偶尔会发生从其增加的流量和汽车冷却器的热负荷产生的制冷剂的增加的压力损失。 简而言之，这种改进涉及可操作地接收中压AP的类型的容量控制阀，用于控制特定量的压缩气体旁路到流体压缩机的吸入侧，作为 所述相对低压LP的线性函数使用相对高压HP与流体压缩机的相对低压力LP之间的压差; 其包括适于调节中压AP的调节装置，使得相对低压LP随着相对高压HP变高而变低，并且所述相对低压LP被制成较高，因为所述相对高压HP 变得更低。
