ABSTRACT:
A reciprocating compressor includes a cylinder block disposed in a chamber formed by a casing. A piston is mounted for reciprocation in a bore of the cylinder block. A valved cylinder head is disposed at an end of the bore. The cylinder head conducts sucked fluid to the bore. The sucked fluid enters the casing through an inlet therein and travels through a suction passage formed by a suction muffler and then through a base muffler before entering the cylinder head. The suction muffler includes exterior holes for communicating the suction passage of the suction muffler with the chamber of the casing, to thereby reduce the suction load occurring at the bore and valve plate.
