Description

Technical Field

[0001] This utility model relates to the field of compressor technology, and more specifically to a compressor intake valve plate and a compressor. Background Technology

[0002] The main components of a refrigerator compressor are the suction and discharge valves. Their operation involves opening and closing these valves to deliver refrigerant to the refrigeration system. During opening and closing, the valve springs are subjected to alternating forces, requiring high fatigue resistance and mechanical strength. Conventional valve springs are circular, offering high reliability. With a constant compressor and specifications, and a consistent refrigeration path, miniaturized suction valves can be designed to ensure compressor efficiency. This allows for faster and more efficient suction, while maintaining a proportional relationship between the valve spring area and mass flow rate. Higher mass flow rate leads to higher compressor efficiency. However, miniaturized valves experience more complex stresses and strains during operation, making fatigue life a critical issue. This places new demands on valve structure and stability. Utility Model Content

The tail is elliptical with straight sides. The maximum length of the tail is three times the minimum width of the cantilever, and the maximum length of the tail is 1.5 times the width of the end. A gap is provided between the tongue spring and the valve body. A vent groove communicating with the gap is provided on one side of the cantilever of the tongue spring.

[0006] Furthermore, the valve plate body has a rectangular structure, and the four corners of the valve plate body have an arc-shaped structure, with one of the corners having a positioning port provided by chamfering.

[0007] Furthermore, mounting holes are provided at the four corners of the valve body.

[0008] Furthermore, the tongue spring includes an end, a cantilever, and a tail. The connection between the two sides of the end and the valve plate body is rounded. The tail has a length of 12.0 mm and a width of 8.1 mm. The end has a width of 6.0 mm. The middle part of the cantilever has a rectangular structure.

[0009] Secondly, this application provides a compressor, including: the compressor suction valve plate described above.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] This invention, by setting the tongue spring to a large tail and a small cantilever, can make the compressor's intake process faster and more efficient while ensuring the miniaturization of the intake valve plate. It can reduce intake resistance, increase intake volume, and thus improve the overall performance and efficiency of the compressor.
