    • There is disclosed a durable compression machine that can be used as a compressor, pump, or actuator. The machine comprises a casing in which a flexible membrane is accommodated. The inside of the casing is partitioned into a compression chamber and a back pressure chamber by the membrane consisting of a diaphragm spring or bellows. The membrane is reciprocated to compress the fluid inside the compression chamber and to force the fluid out of the compression chamber. The back pressure chamber is sealed with a gas under pressure. The pressure inside the back pressure chamber acts in opposition to the pressure inside the compression chamber and is maintained at about half of the pressure obtained in the compression chamber during compression to suppress the flexure of the membrane.
    • 公开了一种可用作压缩机,泵或致动器的耐久压缩机。 机器包括容纳柔性膜的壳体。 壳体的内部由膜片弹簧或波纹管构成的隔膜分隔成压缩室和背压室。 膜被往复运动以压缩压缩室内的流体并迫使流体离开压缩室。 背压室用压力下的气体密封。 背压室内部的压力与压缩室内的压力相反,并且在压缩期间保持在压缩室中获得的压力的大约一半,以抑制膜的挠曲。

    • A variable displacement type compressor has a supply passage for supplying refrigerant gas to a pressure control chamber, a release passage for releasing the refrigerant gas from the pressure control chamber, a first control valve for controlling the amount of the refrigerant gas flowing through the supply passage, a check valve provided between the first control valve and the pressure control chamber and preventing the refrigerant gas from flowing from the pressure control chamber to the first control valve by closing the supply passage and a second control valve for adjusting a cross-sectional area of the release passage from minimum to maximum. The second control valve has a back pressure chamber communicating with the supply passage, a valve chamber forming a part of the release passage and communicating with a suction-pressure region, a valve hole forming a part of the release passage and communicating with the valve chamber and a spool having a valve portion located in the valve chamber. When a pressure in the back pressure chamber increases, the valve portion decreases the degree of opening of the valve hole.
