Volume ratio control system for compressor

A volume ratio control system for a compressor includes: a chamber (118) formed within a housing (112) of the compressor (100); a piston (116) disposed within the chamber (118), wherein the piston (116) is configured to separate the chamber (118) into at least a first portion (120) fluidly coupled to a low pressure side (104) of the compressor and a second portion (122) fluidly coupled to a high pressure side (106) of the compressor; and a biasing device (124) disposed within the chamber, wherein the biasing device (124) is configured to adjust a position of the piston (116) in response to a pressure difference between the low pressure side (104) of the compressor and the high pressure side (106) of the compressor falling below a threshold. 一种用于压缩机的容积比控制系统，其包含：形成于所述压缩机(100)的外壳(112)内的腔室(118)；设置在所述腔室(118)内的活塞(116)，其中所述活塞(116)被配置成将所述腔室(118)分离为至少流体耦合到所述压缩机的低压侧(104)的第一部分(120)和流体耦合到所述压缩机的高压侧(106)的第二部分(122)；以及设置在所述腔室内的偏置装置(124)，其中所述偏置装置(124)被配置成响应于所述压缩机的所述低压侧(104)与所述压缩机的所述高压侧(106)之间的压差下降到阈值以下而调整所述活塞(116)的位置。
