压缩机和阀组装体
摘要：
提供一种压缩效率高的压缩机。阀组装体(280)被设置在压缩室(S1、S2)与注入管道(90)之间。这里，阀组装体(280)具有开口形成部件(281)、阀主体(282)和弹簧部件(283)。开口形成部件(281)形成开口(281a)。阀主体(282)根据从注入管道(90)供给的制冷剂的压力与压缩室(S1、S2)内的压缩中途的制冷剂的压力之差而移动，在从压缩室(S1、S2)侧移动到注入管道(90)侧时，封闭开口(281a)。弹簧部件(283)相对于开口(281a)被配置在注入管道(90)侧，对阀主体(282)向注入管道(90)侧的方向施力。
摘要（英）：

Provided is a compressor having high compression efficiency. A valve assembly (280) is provided between injection piping (90) and a compression chamber (S1, S2). The valve assembly (280) has an opening forming member (281), a valve body (282), and a spring member (283). The opening forming member (281) has an opening (281a) formed therein. The valve body (282) moves according to the difference between the pressure of a refrigerant supplied from the injection piping (90) and the pressure of a refrigerant located within the compression chamber (S1, S2) and being compressed, and closes the opening (281a) when moved from the compression chamber (S1, S2) side toward the injection piping (90). The spring member (283) is disposed on the injection piping (90) side relative to the opening (281a) and applies force to the valve body (282) in the direction toward the injection piping (90).
