摘要： The flapper valve is to be utilized in a compressor of the type having a valve chamber adjacent a discharge or outlet port. The valve comprises a flexible valve member in the valve chamber which has a port closure at the front end thereof to seal the discharge port of the compressor. A backer plate is similarly received in the valve chamber and has one end in engagement with the rear end of the valve member to normally bias the port closure to a position wherein the discharge port of the compressor is closed. The valve member is provided with forwardly extending arms which cooperate with upturned ears on the backer plate to prevent longitudinal and lateral movement of the valve member. Accordingly, the valve member and backer plate need not be connected together prior to placement into the valve chamber. Alternatively, if the member and plate are connected together, their relative positions will be maintained even if the connection breaks.
摘要翻译：挡板阀应用于具有与排放口或出口相邻的阀室的类型的压缩机中。该阀包括在阀室中的柔性阀构件，其在其前端处具有端口封闭件以密封压缩机的排出口。支撑板类似地容纳在阀室中并且具有与阀构件的后端接合的一端，以将端口封闭件正常地偏压到压缩机的排出口关闭的位置。阀构件设置有向前延伸的臂，其与衬垫上的上翻耳配合，以防止阀构件的纵向和横向移动。因此，在安装到阀室之前，阀构件和支承板不需要连接在一起。或者，如果构件和板连接在一起，即使连接断开，它们的相对位置将被保持。

摘要： Liquid refrigerant is injected into the high-pressure side of a rotary compressor so as to cool the refrigerant being compressed to allow it to be useful in cooling the compressor motor. The injection port is located on the bottom face of the compressor chamber, within an area removed from the compressor chamber wall, immediately adjacent the compressor chamber discharge. The feed to the injection port is through a larger tube containing two non-connected capillaries, the first capillary being connected to the inlet of the tube and the second capillary being connected to the injection port. In this manner, a column of liquid remains in the second capillary. The combination of the placement of the injection port and the form of the inlet tubing to the injection port prevents liquid from being carried over into the suction side of the compressor, where efficiency and economy would be diminished, avoids the necessity for a check valve in the suction line to the compressor chamber, and allows for the parts of the compressor chamber to be used with varying compressor rollers without remachining.
摘要翻译：液体制冷剂被注入到旋转压缩机的高压侧，以冷却被压缩的制冷剂，使其可用于冷却压缩机电动机。注射口位于压缩机室的底面上，在与压缩机室壁隔离的区域内，紧邻压缩机室排出口。注入口的进料通过一个较大的管，其中包含两个未连接的毛细管，第一毛细管连接到管的入口，第二毛细管连接到注射口。以这种方式，一列液体残留在第二毛细管中。将注入口的放置和入口管的形式组合到注射端口防止液体被运送到压缩机的吸入侧，其中效率和经济性将被降低，避免了止回阀的必要性到压缩机室的吸入管线，并且允许压缩机室的部件与不同的压缩机辊子一起使用而不需要再加工。
