ABSTRACT:
An inlet port15is divided into a plurality of holes15a,15b,15c,15by ribs61a,61b,61c.For example, when liquid refrigerant is compressed within a compression chamber, the inlet valve21receives excessive load which is about to bend the inlet valve21largely toward the suction chamber side. However, the inlet valve21is supported by the ribs61a,61b,61c,and therefore the inlet valve21is hardly bent, but the inlet port21is positively closed.
