摘要： A rotary compressor of the sliding vane type, in which the vanes of the rotor slide resiliently along the inner surface of the stator the cross section profile of which defines three separate substantially circular arcs one of which has the same radius as the rotor and forms a transition zone or sealing area between the high pressure side and the low pressure side, the profile defining the inlet side or low pressure side having a radius of curvature which is greater than the mean radius of the stator and the profile defining the outlet side or high pressure side having a radius smaller than the mean radius of the stator, whereby the space between the inner surface of the stator increases continuously from substantially zero at the inlet side of the transition zone to its predetermined optimum and thereafter decreases continuously back to substantially zero at outlet side of the transition zone.
摘要翻译：一种滑动叶片式旋转压缩机，其中转子的叶片沿着定子的内表面弹性地滑动，其横截面轮廓限定了三个分开的大致圆弧，其中之一具有与转子相同的半径，并形成过渡区域或高压侧和低压侧之间的密封区域，该轮廓限定入口侧或低压侧的曲率半径大于定子的平均半径，并且限定出口侧或高度的轮廓压力侧的半径小于定子的平均半径，由此定子的内表面之间的空间从过渡区的入口侧的基本上从零增加到其预定的最佳值，然后在出口侧的过渡区。

摘要： An improvement in the construction and operation of the capacity control slide gate for a screw compressor of the type having two helical intermeshing rotors in operative engagement with each other, radially surrounded by a cylindrical housing of 8-shaped cross-section, is disclosed. The novel slide gate is guided not only by the conventional trough-like recess in the compressor housing, but also by an opening in the outlet end closure of the compressor corresponding to the profile of the slide gate and by a piston rod attached to the slide gate and slidably journalled in the rotor housing.
摘要翻译：公开了一种用于螺杆式压缩机的容量控制滑动门的改进，所述螺杆式压缩机具有两个螺旋啮合转子，所述两个螺旋压缩机彼此操作地接合，由具有8形横截面的圆柱形壳体径向包围。新型滑动门不仅由压缩机壳体中的常规槽形凹槽引导，而且还通过压缩机的出口端盖中的开口对应于滑动门的轮廓以及连接到滑块的活塞杆门并可滑动地安装在转子壳体中。

摘要： A REFRIGERATING SYSTEM PROVIDED WITH MULTI-STAGE THROTTLING AND WITH A POSITIVE DISPLACEMENT COMPRESSOR OF THE ROTARY TYPE, THE CASING OF THE COMPRESSOR BEING PROVIDED BETWEEN ITS LOW PRESSURE AND HIGH PRESSURE PORTS WITH ONE OR MORE ADMISSION PORTS FOR INTERMEDIATE PRESSURE GAS FROM LIQUID SEPARATORS LOCATED BETWEEN THROTTLING POINTS. THE GAS FORMED DURING THROTTLING IS SUPPLIED THROUGH THESE ADMISSION PORTS TO THE WORKING COMPARTMENT OF THE COMPRESSOR. THE OPENING AND CLOSING OF THE ADMISSION PORTS IS ACHIEVED BY THE ACTION OF THE COMPRESSOR WHICH HAS ITS ROTOR LOBES OPERATIVE AS VALVES FOR THE ADMISSION PORTS.
