A combined muffler and separator plate for use in a hermetic compressor having a casing and compressing means in said casing comprising:
- a single member having a first portion adapted to be located in and sealed to said casing;
- said member having a second portion adapted to be fixedly sealed to said compressing means whereby said member coacts with said casing and said compressing means to divide said casing into a suction plenum and a discharge plenum;
- said member having a third portion defining a muffler.
A combined muffler and separator plate for use in a hermetic compressor having a casing and compressing means in said casing comprising:
- a single member having a first portion adapted to be located in and sealed to said casing;
- said member having a second portion adapted to be sealed to said compressing means whereby said member coacts with said casing and said compressing means to divide said casing into a suction plenum and a discharge plenum;
- said member having a third portion defining a muffler;
- valve means;
- and
- said third portion including means for receiving and supporting said valve means.
A combined muffler and separator plate comprising:
- a single member having first, second, and third portions;
- said first portion defining a muffler means;
- said second portion extending radially outwardly from said first portion and including an annular section adapted to be sealed to the compressing means of a hermetic compressor;
- said third portion located radially outward from said second portion and adapted to be sealed to the casing of a hermetic compressor whereby said second portion will function as a separator plate for separating a suction plenum from a discharge plenum.
A combined muffler, separator plate and check valve comprising:
- valve means;
- a single member having first, second and third portions;
- said first portion having means for receiving and supporting said valve means and defining a muffler means;
- said second portion surrounding said first portion and including a region adapted to be sealed to the compressing means of a hermetic compressor;
- said third portion surrounding said second portion and adapted to be sealed to the casing of a hermetic compressor whereby said second portion will function as a separator plate for separating a suction plenum from a discharge plenum.
