Sealed type motor compressor

Claim 2

A sealed type motor compressor comprising a motor section and a compressor section resiliently supported within a sealed enclosure, a suction pipe extending through a side wall of said sealed enclosure, a suction muffler disposed on a side wall of said compressor section, and an insert pipe inserted into and extending into the interior of said sealed enclosure with a slight clearance between it and an inlet port formed in a side wall of said suction muffler, and a closely coiled spring in the form of a cylinder secured to said suction pipe and said insert pipe for interconnecting them, said closely coiled spring having a torsional moment which provides a biasing force causing said insert pipe to abut against said inlet port, said suction muffler including a cup-shaped body formed of a synthetic resin and divided into at least upper and lower sections, a closure member covering an opening of said body and a partition plate mounted between said body and said closure member, said cup-shaped body being open at its top surface and formed at its bottom surface with an aperture, through which a communication pipe is fitted into a suction port formed in said compressor section to securely support said cup-shaped body, said partition plate being formed with a through hole, having a position which is offset from an extension of said communication pipe, said inlet port being provided on the side of said closure member.

Claim 3

A sealed type motor compressor comprising a motor section and a compressor section resiliently supported within a sealed enclosure; a suction pipe having a portion extending into said sealed enclosure; a suction muffler fixed to said compressor section, said suction muffler including a cup-shaped body formed of a synthetic resin and divided into at least two sections, a closure member covering an opening of said body, a curved partition plate formed with a through hole and resiliently interposed between said body and said closure member, apertures formed on one of said body and said closure member, and latches formed on the other of said body and said closure member and adapted for engagement with said apertures, said body being formed with an aperture for receiving a communication pipe having a flange for engagement with a peripheral edge of said aperture, said suction muffler being secured to a cylinder head by inserting said communication pipe into said aperture of said body and forcedly fitting said communication pipe into a suction port formed in said cylinder head while placing a resilient member around the periphery of said communication pipe between said suction muffler and said cylinder head; an insert pipe adapted to extend through an inlet port of said suction muffler with a slight clearance therebetween; and a closely coiled spring in the form of a cylinder interposed between said suction pipe portion extending into said sealed enclosure and said insert pipe; said closely coiled spring being secured to said suction pipe portion and insert pipe and having a given torsional moment to provide a biasing force acting between said inlet port and said insert pipe.

Claim 4

A sealed type motor compressor comprising a motor section and a compressor section resiliently supported within a sealed enclosure; a suction pipe having a portion extending into said sealed enclosure; a suction muffler fixed to said compressor section, said suction muffler including a cup-shaped body formed of a synthetic resin and divided into at least two sections, a closure member covering an opening of said body, a curved partition plate formed with a through hole and resiliently interposed between said body and said closure member, apertures formed on one of said body and said closure member, and latches formed on the other of said body and said closure member and adapted for engagement with said apertures, said body being formed with an aperture for receiving a communication pipe having a flange for engagement with a peripheral edge of said aperture, said suction muffler being secured to a cylinder head by inserting said communication pipe into said aperture of said body and forcedly fitting said communication pipe into a suction port formed in said cylinder head while placing a resilient member around the periphery of said communication pipe between said suction muffler and said cylinder head; an insert pipe adapted to extend through an inlet port of said suction muffler with a slight clearance therebetween; and a closely coiled spring in the form of a cylinder interposed between said suction pipe portion extending into said sealed enclosure and said insert pipe; said closely coiled spring being secured to said suction pipe portion and insert pipe and having a given torsional moment to provide a biasing force acting between said inlet port and said insert pipe.
