ABSTRACT:
A gas compressor has a cylinder in which a refrigerant gas is compressed and a side block mounted to an end surface of the cylinder. The side block has suction holes each having a first end opening to an outer surface of the side block and a second end opening into the cylinder. A front head has a suction port, an inner surface, and a hollow portion disposed in the inner surface. The front head is disposed on an outer surface of the side block so that the hollow portion and the outer surface of the side block form suction passages extending from the suction port to respective suction holes of the side block. Each of the suction passages form a main flow passage along which refrigerant gas flows from the suction port to a corresponding one of the suction holes of the side block. The hollow portion has a generally flat wall surface at a region corresponding to each of the main flow passages.
