COMPRESSOR AND VALVE ASSEMBLY

Provided is a compressor whose compression efficiency is high. A valve assembly (280) is provided between a compression chamber (S1, S2) and an injection pipe (90). Here, the valve assembly (280) has an opening forming member (281), a valve body (282), and a spring member (283). The opening forming...

Summary:Provided is a compressor whose compression efficiency is high. A valve assembly (280) is provided between a compression chamber (S1, S2) and an injection pipe (90). Here, the valve assembly (280) has an opening forming member (281), a valve body (282), and a spring member (283). The opening forming member (281) forms an opening (281a). The valve body (282) moves in accordance with differences between the pressure of refrigerant supplied from the injection pipe (90) and the pressure of refrigerant in the middle of compression in the compression chamber (S1, S2) and blocks the opening (281a) when the valve body has moved from the compression chamber (S1, S2) side to the injection pipe (90) side. The spring member (283) is disposed on the injection pipe (90) side of the opening (281a) and applies force in the direction of the injection pipe (90) to the valve body (282).
