    摘要： In its unstressed state, a suction valve is spaced from its valve seat such that the suction valve must be deformed against its inherent spring force in order to achieve seating. The spring force due to deformation provides an opening bias to the suction valve such that it opens earlier in the suction stroke and offsets the effects of adhesion due to the presence of oil between the seating surface and the valve.

    摘要翻译： 在其不受应力状态下，吸入阀与其阀座间隔开，使得吸入阀必须抵抗其固有的弹簧力而变形，以便实现就座。 由于变形引起的弹簧力提供了对吸入阀的打开偏压，使得其在吸入行程中更早地打开，并抵消由于在座面和阀之间存在油而引起的粘附效果。

    摘要： A method of operating a refrigeration system uses a plurality of compressors in connected parallel. The method includes returning refrigerant and oil to the compressors, the refrigerant also having oil entrained therein, separating the oil entrained in the refrigerant, and returning more of the oil entrained in the refrigerant to a lead compressor of the plurality of compressors regardless of whether the lead compressor is operating. The method also includes connecting the oil sumps of all of the plurality of compressors such that oil is supplied from the lead compressor to at least one non-lead compressor of the plurality of compressors when the at least one non-lead compressor is operating.

    摘要： A refrigeration system with two or more compressors configured to compress a flow of refrigerant with oil entrained therein. A suction flow piping arrangement is configured to supply a flow of refrigerant and oil to the two or more compressors. The suction flow piping arrangement has a suction header configured to carry the flow of refrigerant and oil, and a primary compressor supply conduit connected to the suction header. The primary compressor supply conduit supplies refrigerant and oil to a first compressor of the two or more compressors. A secondary compressor supply conduit branches off from the suction header. The secondary compressor supply conduit supplies refrigerant to a second compressor of the two or more compressors. The primary compressor supply conduit is configured to supply more oil to the first compressor than the secondary compressor supply conduit supplies to the second compressor.

    摘要： A multi-stage compressor unit for a refrigeration system configured to circulate a refrigerant comprises a first compressor sub-unit having a first stage and a second stage, and a second compressor sub-unit in parallel with the first compressor sub-unit and having a first stage. The first and second stages of the first compressor sub-unit each have a suction port and a discharge port. The first compressor sub-unit is configured to receive and compress a first portion of the refrigerant from an evaporator. The first stage of the second compressor sub-unit is configured to compress a second portion of the refrigerant.
