摘要： A piston for a compressor comprising a ring groove on the outer circumferential surface of the piston, and a discontinuous ring seal member with opposite split ends made of a plastic material and fitted in the ring groove. The ring member having an outer surface comprising a main sealing portion having an axially uniform shape and an outwardly circumferentially projecting flexible lip portion. Also, the inner surface of the ring member comprises an inner bearing portion able to come into contact with a first portion of a bottom surface of the ring groove such that the flexible lip portion of the outer surface is brought into contact with a cylinder wall of the cylinder bore and preflexed inwardly. An inner pressure receiving portion is formed adjacent to the inner bearing portion to receive pressure from the compression chamber, to further flex the flexible lip portion upon a compression stroke of the compressor and thereby allow the ring member to expand and the main sealing portion to come into contact with the cylinder wall of the cylinder bore.
摘要翻译：一种用于压缩机的活塞，包括在活塞的外圆周表面上的环形槽，以及具有相对的分开端部的不连续的环形密封件，其由塑料材料制成并装配在环形槽中。环形构件具有外表面，该外表面包括具有轴向均匀形状的主密封部分和向外周向突出的柔性唇部部分。此外，环构件的内表面包括能够与环槽的底面的第一部分接触的内轴承部，使得外表面的柔性唇部与气缸壁接触气缸内孔并向内偏转。内压接部分邻近内轴承部分形成，以承受来自压缩室的压力，以便在压缩机的压缩冲程时使挠性唇部进一步挠曲，从而允许环件膨胀并且主密封部分来与气缸孔的气缸壁接触。

摘要： In a discharge pulsation damping apparatus of a compressor according to this invention, an expansion muffler 46 and a resonance muffler 58 each having a predetermined capacity are defined inside cylinder blocks 11 and 12 through partitions 59 and 60 so that the resonance muffler 58 is situated at a position higher than the expansion muffler 46 in a gravitational direction (vertical direction). The expansion muffler 46is connected to discharge chambers 38 and 39 and to an outlet 48, and both mufflers 46 and 58 are communicated by a communication passage 61 formed in the partitions 59and 60. The capacity of the resonance muffler 58, the open sectional area of the communication passage 61 and its passage length are set to values such that a pressure change capable of offsetting specific frequency components of the discharge pulsation inside the expansion muffler 46 can be generated inside the resonance muffler 58. The lubricant condensed inside the resonance muffler 58 is fed back into the expansion muffler 46 through the communication passage 61.
