Embodiment Construction

[0014] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0015] The structure diagram of rotary air compressor shown in Fig. 1, cylinder 1 is its stator, and rolling piston 8 is arranged eccentrically in cylinder 1, as its rotor, and it is driven by rotating shaft 2, and piston 8 is tangent to the inner wall cylindrical surface of cylinder 1, Sliding plate 5 is housed in the cylinder body (the structure of sliding plate 5 is as figure 2 Shown), the root of the slide plate 5 is located in the cylinder body and has a spring groove 13, there is a spring 4 between the slide plate 5 and the cylinder 1, and the top of the slide plate 5 has a transverse U-shaped or arc-shaped groove. A ball-head needle roller 6 is placed in the groove, the needle roller 6 can roll in the groove, the needle roller 6 is exposed to the groove, and the elastic force of the spring 4 makes the needle roller 6 close to the cylin...

Abstract

The invention discloses a rotary air compressor. The compressor comprises a compressor cylinder, a rolling piston driven by a rotary shaft is arranged in the compressor cylinder, and the rolling piston is tangent to the cylindrical face of the inner wall of the cylinder. A sliding piece is installed between a cylinder body and the piston. A transverse groove is formed in the top end of the sliding piece, a roller pin with a round head is placed in the groove, and the roller pin can roll in the groove and extends out of the groove. The root portion of the sliding piece is located in the cylinder body and is provided with a spring groove, a spring is installed between the sliding piece and the cylinder body, and the roller pin is attached to the face of the piston through elastic force of the spring. The rotary air compressor has the advantages that the sliding piece is installed in the cylinder body and is not prone to damage; rolling friction exists between the sliding piece and the piston; energy consumed for friction is little; the utilization rate of the energy is increased; the abrasion amount of the piston is reduced; the service life is prolonged.

Description

technical field [0001] The invention relates to a compressor, in particular to a rotary air compressor. Background technique [0002] Rotary air compressors are suitable for small air conditioners, especially for household air conditioners. Its main features are: the piston is used for rotary motion, and the compression work is smooth and stable. In addition, the rotary air compressor has no clearance volume and no interference of re-expansion gas, so it has high compression efficiency, few parts, small volume, light weight, good balance performance, low noise, complete protection measures and low power consumption, etc. advantage. The disadvantage is that the air compressor has high requirements on material, processing accuracy, heat treatment, assembly process and lubrication system. Since it needs to be sealed by the lubricating oil in the movement gap, in order to separate the oil from the exhaust, the casing must be made into a high-pressure compressor. . There is s...
