Reciprocating parallel flow compressor with discharge muffler

摘要

A plurality of gas compression means including a cylinder and a piston in which the piston is cooperated with a compressor by conversion of the rotating motion of a crankshaft provided on a driving source to a reciprocating motion using a scotch yoke mechanism. An expansion muffler is attached to an outlet port of at least one of the gas compression means. Four gas compression means are disposed in opposite one another in a cross shape. Gases compressed by three of the gas compression means are discharged into a cylinder head of the other gas compression means by a connecting tube, and are joined with the flow of gas compressed by the other gas compression means, to be discharged in concentration from the cylinder head of the other gas compression means. The expansion muffler is attached to the outlet port of the cylinder head of the other gas compression means.
