Embodiment 1

[0052] Such as Figure 8 to Figure 11 As shown, the piston is used in a compressor, and the piston is provided with a lightening space 10 for reducing the mass of the piston; wherein, the lightening space 10 includes a first lightening area 11, and the piston includes a space for forming a compression chamber with the cylinder liner 1 and the cylinder 2 5, the first relief area 11 is spaced apart from the compression surface 31, so that when the pressure in the compression chamber 5 is too high, the partial structure of the piston is elastically deformed toward the side of the first relief area 11 to reduce the excessive pressure. Compression; at the same time, the relief space 10 includes a second relief area 12, the piston includes an abutment surface 32 for abutting against the inner wall of the cylinder 2, and the second relief area 12 is opened on the abutment surface 32 to reduce the abutment surface 32 and the friction between the inner wall surface of cylinder 2.

Embodiment 2

[0073] The difference between the second embodiment and the first embodiment is that only the first relief area 11 is provided, which is beneficial to simplify the manufacturing process.

[0074] Optionally, as in Figure 12 to Figure 14 As shown, the shape of the section of the first lightening area 11 perpendicular to the rotation axis of the piston is arc-shaped.

Embodiment 3

[0076] The difference between the third embodiment and the second embodiment is that the cross-sectional shape of the first lightening area 11 is different, specifically, the cross-sectional shape of the first lightening area 11 perpendicular to the rotation axis of the piston is polygonal. In this way, the processing technology can be further simplified.

[0077] Such as Figure 15 with Figure 16As shown, the cross section of the first lightening region 11 perpendicular to the rotation axis of the piston is rectangular, which has the advantages of simple structure and easier processing.

Abstract

The invention provides a piston and a compressor. The piston is applied to the compressor, wherein the lightening space for lightening the mass of the piston is arranged on the piston, the lighteningspace comprises a first lightening area, the piston comprises a compression surface used for defining a compression cavity with an air cylinder sleeve and an air cylinder, the first lightening area and the compression surface are arranged in a spaced mode, when the pressure in the compression cavity is too large, a part of the structure of the piston elastically deforms towards one side of the first lightening area to reduce overcompression; and / or the lightening space comprises a second lightening area, the piston comprises an abutting surface used for abutting against an inner wall of the air cylinder, and the second lightening area is formed on an abutting surface so as to reduce friction force between the abutting surface and the inner wall face of the air cylinder. The piston is advantaged in that a problem that a compressor in the prior art has large noise is solved.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a piston and a compressor. Background technique [0002] The rotary cylinder piston compressor is a new type of positive displacement compressor, such as Figure 1 to Figure 4 As shown, the rotary cylinder piston compressor usually includes a cylinder liner 1', a cylinder 2', a piston 3', a rotating shaft 4', an upper flange 6', a lower flange 7', an upper limit plate 8' and a lower limit plate 9' Wherein, the cylinder 2' is installed in the cylinder liner 1', the piston 3' is installed in the cylinder 2', the rotating shaft 4' is installed in the installation hole of the piston 3', and the rotation axes of the cylinder 2' and the rotating shaft 4' are arranged eccentrically. refer to figure 2 with Figure 5 It can be seen that by driving the rotating shaft 4' to rotate, the rotating shaft 4' drives the cylinder 2' to rotate through the piston 3', thereby realizing the sim...
