    摘要： Abstract: The present invention relates to an arrangement integrated by at least one reed-type suction valve and at least one flexible stop which, arranged within the compression cylinder of the compressor, acts as end-of-stroke for the movement of said suction valve. Thus, flexible stop (5) comprises an angular inertial arrangement, so that it comprises a free end (51 ) spaced from the free end of suction valve (3). In addition, free end (51) of flexible stop (5) is cooperative to the movement of piston (12).

    摘要： Load sharing is achieved in a multiple compressor system by a program in a computer which sends signals to, and receives data from, a microcontroller located at each compressor. One compressor, designated as the lead compressor, furnishes its operating parameters, via the computer, to all the other, lag, compressors. The operating parameters include inlet valve position and bypass valve position of each compressor and the microcontroller controls the actuation of both valves. When system demand decreases, compressors are gradually unloaded, and then stopped to go off-line. When system demands increase, compressors are first started, and then gradually loaded before going on-line. Compressors go both on-line and off-line subject to certain time delays so that compressors are gradually added to, or shed from, the load. To equalise running time, all compressors in the system may undergo a periodic rotation and compressors go off-line in reverse order that they came on-line.

    摘要翻译： 通过在位于每个压缩机的微控制器发送信号并从其接收数据的计算机中的程序，在多压缩机系统中实现负载共享。 指定为主压缩机的一个压缩机通过计算机将其工作参数提供给所有其他滞后压缩机。 操作参数包括进气阀位置和每个压缩机的旁路阀位置，微控制器控制两个阀的启动。 当系统需求减少时，压缩机逐渐卸载，然后停止离线。 当系统需求增加时，压缩机首先启动，然后在上线之前逐渐加载。 压缩机经过一段时间的延时，在线和离线，从而使压缩机逐渐添加到负载中或从负载中流出。 为了平衡运行时间，系统中的所有压缩机可能经历周期性旋转，压缩机以与之相反的顺序离线运行。
