Embodiment Construction

[0042] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

[0043] Such as figure 1 As shown, the hermetic compressor of the present invention is composed of a motor mechanism generating a driving force and a compression mechanism receiving and transmitting the driving force generated by the motor mechanism to compress refrigerant gas.

[0044] The compression mechanism part is composed of a cylinder 5 that compresses refrigerant gas on the upper side of the motor mechanism, a cylinder block B with an insertion hole 6, and is pressed into the rotor of the motor mechanism part through the insertion hole, and has an eccentric part 7a on the upper part. The crankshaft 7 is composed of a piston that reciprocates and linearly moves inside the cylinder, and a connecting rod that connects the eccentric portion of the piston and the crankshaft to convert the rotational motion of the crankshaft into the reciprocating linear motion ...

Abstract

The valve assembly for sealed compressor capable of simplifying structure of suction valve and exhaust valve for the refrigerant flowing in and from the cylinder and raising production efficiency has cylinder cap between the cylinder to compress the refrigerant gas and the cylinder cap hood and with suction port and suction valve to open and shut the suction port in the cap. There is a valve inserting slot formed on one side of the cylinder cap and the suction valve is inserted into the slot and is opened and shut by the suction force and compressing force of the cylinder.

Description

technical field [0001] The present invention relates to a hermetic compressor, in particular to a valve assembly of a hermetic compressor, which simplifies the structure of the suction valve and the discharge valve for regulating the entry and exit of refrigerant gas from the cylinder, and at the same time makes the dead The volume [dead volume] reaches the minimum. Background technique [0002] In general, a compressor is a machine that compresses and discharges the inhaled working fluid, and performs the function of compressing the refrigerant gas passing through the evaporator to a high temperature and high pressure in a refrigeration and air conditioning device such as a refrigerator or an air conditioner. A motor mechanism unit and a compression mechanism unit that generate such a compressor driving force are collectively called a hermetic compressor. [0003] In addition, the above-mentioned hermetic compressors are also classified into rotary compressors, reciprocati...
