Abstract:
1. A hermetic compressor comprising: a hermetic container for storing oil; and a compressing element accommodated in the hermetic container for compressing refrigerant gas; wherein the compressing element has a compression chamber, a cylinder forming the compression chamber, a piston inserted into the cylinder for reciprocating therein, and a suction muffler having one end communicating with the compression chamber; and wherein the suction muffler has a sound deadening space having a first surface, an inlet pipe having one end opening in the sound deadening space and another end opening to the hermetic container, an outlet pipe having one end opening in the sound deadening space and another end opening to the compression chamber, said one end opening in the sound deadening space being disposed adjacent the first surface of the sound deadening space, a gas flow forming part forming a gas flow that enables the gas to flow in a constant direction in the sound deadening space by said one end opening of the outlet pipe disposed adjacent the first surface of the sound deadening space being open so that the gas flowing into the compression chamber from the one end opening of the outlet pipe disposed adjacent the first surface of the sound deadening space flows and circulates in a constant direction along the first surface of the sound deadening space and by opening the one end opening of the inlet pipe at a place which the gas flows into the sound deadening space, and an oil discharge opening provided in a downstream side of the gas flow in a lower part of the sound deadening space, wherein the outlet pipe includes a right angle bend in the sound deadening space, the outlet pipe being separate and disconnected from the inlet pipe, and the gas flow forming part is formed by a combination of the outlet pipe and the inlet pipe, and wherein the one end of the inlet pipe is located at a first portion of the inlet pipe and the one end of the outlet pipe is located at a first portion of the outlet pipe and the first portion of the outlet pipe is parallel to the first portion of the inlet pipe within the sound deadening space.
