Problems solved by technology

[0006] However, in the valve device of the prior art hermetic compressor as described above, since both ends of the brake device are inserted into the valve plate, and are pressed and fixed only by the discharge cover, the fixing of the brake device is not necessary. Reliable, so that when the brake device gaps due to machining errors or assembly errors during operation, the disadvantage of increased compressor noise will occur

Embodiment Construction

[0026] Below, the valve device of the hermetic compressor of the present invention is described in detail with reference to the accompanying drawings and implementation:

[0027] Such as figure 1 As shown, a valve device of a hermetic compressor includes an electric part 100 arranged in the inner space of the container 1, which is composed of a stator 110, a rotor 120 and a rotating shaft 130 that generate rotational force under the action of an externally supplied power supply; In the inner space of the container 1 , there is a compression unit 200 coupled to the rotating shaft 130 of the motor unit 100 and sucking and compressing the refrigerant by utilizing the transmitted rotational force generated by the motor unit 100 .

[0028] The compression part 200 is provided in a lateral direction in the inner space of the container 1, and the following components are provided on one side thereof: a cylinder 210 constituting a compression space V1 in a radial direction; The sleev...

Abstract

The invention discloses a valve device of an enclosed type compressor, characterized in that, a convex-shaped support protruding part is arranged on a discharge cap facing to the direction of a brakedevice, and one part of a steel plate washer is prolonged to form a support plate part, thereby flexibly supporting the part between the discharge cap and the brake device. Therefore, even the discharge cap is machined with errors or the brake device is assembled with errors, the flexible support can be also formed for the brake device, thereby preventing the vibration of the brake device and thenoise increase. The valve device of the invention is mainly applied to a refrigerator, also is widely applied to refrigeration systems such as an air conditioner and the like.

Description

technical field [0001] The invention belongs to a valve device, in particular to a valve device of a hermetic compressor which controls the discharge of the compressed refrigerant after the refrigerant is sucked into the cylinder body. Background technique [0002] Generally speaking, a hermetic compressor is equipped with an electric part that can generate driving force inside the airtight container, and a compression part that compresses the refrigerant using the power generated by the electric part transmitted to it, and is mainly used in refrigerators or air conditioners. etc. on the refrigeration system. [0003] According to the compression method and the type of refrigerant used, hermetic compressors can be divided into various forms. Among them, the reciprocating compressor consists of a linear cylinder and a piston inserted into the cylinder in a slidable state to form a refrigerant compression mechanism. At the same time, a valve assembly that can adjust the intak...
