ABSTRACT:
A reciprocating compressor includes a piston mounted for reciprocation in a bore of a cylinder. A cylinder head is mounted on the cylinder at one end of the bore for conducting fluid to and from the bore. A muffler is connected to the cylinder head for conducting the fluid to the bore. The muffler includes a base member and a muffler body secured thereto. The base member includes a recess in which a leading portion of the muffler body is installed. Hooks formed on the leading portion become caught against securing edges formed in the recess to resist rearward withdrawal of the muffler body. A floor of the body is elastic, to push the hooks against the securing edges. Also, side walls of the recess push elastically against the leading portion of the muffler body. Consequently, there is no play between the muffler body and base member which could produce noisy rattling during operation of the compressor.
