## Abstract

An improved suction noise muffler mounting apparatus for a hermetic compressor which is capable of more simply mounting a suction noise muffler to a cylinder head, for thus reducing the number of fabrication processes and increasing the productivity of a hermetic compressor, which includes a suction noise muffler head having a protrusion having a predetermined height and formed on the upper surface thereof and integrally engaged to an upper end of the suction noise muffler, and a fixing member provided for mounting the suction noise muffler to a portion of the cylinder head.

## Claims

### Claim 1

In a suction noise muffler mounting apparatus for a hermetic compressor having a cylinder body, a cylinder head, a plurality of bolts, and a suction noise muffler mounted to a portion of the cylinder head for reducing noise generated in the interior of the hermetic compressor, a suction noise muffler mounting apparatus for stably mounting the suction noise muffler to a portion of the cylinder head, comprising:
a suction noise muffler head having a protrusion having a predetermined height and formed on the upper surface thereof and integrally engaged to an upper end of the suction noise muffler; and
a fixing member provided for mounting the suction noise muffler to a portion of the cylinder head, with said fixing member including:
a circular section having a bolt receiving hole into which a bolt is inserted; and
a pressing section extended from the circular section and having a hole into which the protrusion of the suction noise muffler head toward the cylinder head is inserted for pressing the upper surface of the suction noise muffler head.
