Problems solved by technology

In order to immerse the screw mounting part in the screw groove of the cylinder 131 and install it from the upper part to the lower part, the bearing mounting hole 156 formed part of the end difference part of the upper bearing 132 is affected by the continuous exhaust load caused by the discharge of high-temperature and high-pressure refrigerant. Deformation occurs, which in turn causes deformation of the end face of the forming part of the bearing mounting hole 156 of the upper bearing 132 when the stopper 151 and the pilot valve 152 are installed, resulting in problems such as leakage and performance degradation of the cylinder 131

Embodiment Construction

[0032] The installation structure and operating principle of the discharge valve assembly of the hermetic rotary compressor of the present invention will be described below with reference to the drawings and embodiments.

[0033] For the installation structure of the airtight rotary compressor exhaust valve assembly of the present invention, its structure mainly includes a cylinder for compressing refrigerant and an exhaust hole for discharging the compressed refrigerant on it. The side cylinder is provided with a groove 57 in which the head 53a of the screw mounting part 53 is inverted, and is clamped on the lower end surface of the fixed upper bearing 32 with a through hole, and the valve is installed through the threaded part 53b of the screw mounting part 53. The pilot valve 52 of the hole 55 is fastened together with the stopper 51 having the threaded hole 54 .

[0034] Such as Figure 1 to Figure 6 As shown, the hermetic rotary compressor 100 includes a compression mech...

Abstract

An installation structure of the exhaust valve assembly for sealed rotary comprssor has a cylinder for comprssing cold medium and the exhaust hole on the cylinder for discharging the compressed cold medium. The screw part is reversely arranged in the slot in cylinder and close to said exhaust hole and clamped to the lower end face of upper bearing with through hole for fastening the pilot valve and position limiter together. Its advantages are small installation force, less deformation, no leakage and high compression efficiency.

Description

technical field [0001] The present invention relates to a hermetic rotary compressor, and more particularly, provides a discharge valve assembly mounting structure for a hermetic rotary compressor for discharging refrigerant compressed in a cylinder. Background technique [0002] Such as figure 1 , figure 2 As shown, the compressor is composed of a compression mechanical part 130 formed inside the airtight container 110 to suck / compress / discharge a refrigerant, and an electric mechanical part 120 to drive the compression mechanical part 130 . [0003] The electromechanical part 120 is composed of the following structures: a stator 121 that introduces power to generate magnetic force; a rotor 122 that rotates according to the magnetic force of the stator 121; a rotating shaft 123 that is pressed into the inner diameter of the rotor 122. [0004] The compression mechanical part 130 includes the following structure: the air cylinder 31 which is provided after compressing the...
