    摘要： A wrist pin and wrist pin retainer are combined in a subassembly which prevents inadvertent removal of the retainer from the assembly. The subassembly is placed in a bore defined by a piston and a connecting rod with at least one annular groove formed in the bore. When the subassembly is located in the bore, the retainer coacts with the annular groove to secure the wrist pin in the bore.

    摘要： In addition to seating on its valve seat during the combined compression and discharge stroke, the suction valve seats on the structure associated with the valve seat which has at least one shallow recessed area. In seating on its valve seat, the suction valve seats on the structure defining the shallow recesses to trap fluid therein. The recesses serve to reduce the area available for adhesion and the trapped fluid pressure provides an opening bias to the suction valve. If necessary, or desired, restricted communication between the compression chamber and the shallow recess can take place to provide a higher pressure in the recess at the time of transition from discharge to suction.

    摘要翻译： 除了在组合的压缩和排出行程之内安装在其阀座上，吸入阀位于与具有至少一个浅凹陷区域的阀座相关联的结构上。 在座阀座上，抽吸阀位于结构上，形成浅凹槽以在其中捕获流体。 这些凹槽用于减小可用于粘合的面积，并且被捕获的流体压力为吸入阀提供打开偏压。 如果需要或期望，可以发生压缩室和浅凹槽之间的有限连通，以在从排放到抽吸的过渡时在凹部中提供更高的压力。

    摘要： In a compressor having an oil sump located therein, a restricted communication is provided between the oil sump and the suction plenum. As a result, froth generation due to a rapid pressure drop in the oil sump is reduced. A relief valve is provided to limit the pressure differential between the suction plenum and the oil sump.

    摘要： In a compressor where an oil pump is driven by a crankshaft through a drive tang with oil passing through the drive tang. The bolts holding the drive tang in place tend to agitate the oil and create foam. To prevent foam from being drawn into the oil pump, the agitation is isolated by a sub-chamber defined in part by a spring retainer while oil is supplied via a tube extending through the sub-chamber.

    摘要： A method of operating a refrigeration system having at least three compressors, in which each compressor has an oil sump with oil at an oil level. The method includes separately connecting the oil sumps of the at least three compressors. Each separate connection allows oil flow only between the oil sumps of two of said compressors thereby preventing bypass flow. The method further includes flowing oil between oil sumps of the at least three compressors and along the separate connections to tend to equalize the oil levels among the oil sumps of the at least three compressors.

    摘要： A screw compressor (10) comprises a housing (12, 14, 16), a slide valve assembly (23) and a pulsation damper. The housing (12, 14, 16) receives a supply of working matter from a pair of intermeshing screw rotors (18, 20), and comprises a slide recess (51), a pressure pocket (32), and a piston cylinder (54). The slide valve assembly (23) regulates the capacity of the screw compressor (10), and comprises a slide valve (36) axially movable within the slide recess (51) and the pressure pocket (32), a piston head (40) axially movable within the piston cylinder (54), and a piston shaft (38) connecting the slide valve (36) with the piston head (40). The pulsation damper comprises a flange (58) for separating the pressure pocket (32) from the piston cylinder (54), a bore (60) for receiving the piston rod (38), and a damping channel (46A) extending through the flange (58).
