    • A gas compressor includes a housing defining a compression chamber, a crankshaft having an eccentric surface radially offset from the axis of rotation of the crankshaft, an orbiting ring rotatably mounted on the eccentric for rotation about an axis offset from the shaft axis, a cylindrical post coaxial with the axis of the housing passages for carrying gas to and from the compression chamber, vanes movable radially with respect to the orbiting ring, and pressure sensitive valves that open exhaust passages from the compression chamber. The orbiting ring rotates in continual contact with the inner surface of the housing and the outer surface of the cylindrical post. Compression occurs within a first stage space and a second stage space, each space divided into compression chambers by the sliding vanes and contact between the ring and post or between the ring and housing. An intermediate pressure chamber is located in one end of the housing and this chamber can be configured to allow for intercooling of the refrigerant. It is also possible to provide gas separation of the discharge gas and return the separated gas to the intermediate chamber for improved efficiency of the compressor.
    • 气体压缩机包括限定压缩室的壳体,具有径向偏离曲轴旋转轴线的偏心表面的曲轴,可旋转地安装在偏心件上以绕轴轴线偏转的轴线旋转的旋转环,圆柱形柱 与用于将气体输送到压缩室和从压缩室输送气体的壳体通道的轴线同轴,可相对于绕动环径向移动的叶片以及从压缩室打开排气通道的压力敏感阀。 旋转环与壳体的内表面和柱形柱的外表面持续接触。 压缩发生在第一级空间和第二级空间内,每个空间由滑动叶片分隔成压缩室,并在环和柱之间或环与壳体之间接触。 中间压力室位于壳体的一端,该腔室可构造成允许制冷剂的中间冷却。 也可以提供放电气体的气体分离并将分离的气体返回到中间室,以提高压缩机的效率。
