Problems solved by technology

[0005] However, in the above-mentioned Wankel compressor 1, the refrigerant flowing into the cylinder 10 through the rotation of the rotor 11 is compressed and output, and the rotor 11 and the inner wall of the cylinder 10 are damaged due to the continuous friction between the rotor 11 and the cylinder 10. wear problem
Due to the wear between the rotor 11 and the inner wall of the cylinder 10, there is a gap, and the refrigerant leakage and pressure loss are caused by passing through the gap.
The friction between the rotor 11 and the cylinder 10 generates noise, which greatly reduces the performance of the Wankel compressor 1 itself

Embodiment Construction

[0020] Such as Figure 4 As shown, the structure for preventing wear of the Wankel compressor 1a of the present invention changes the volume of the space in the cylinder through the eccentric movement of the triangular rotor 11, and realizes the process of sucking, compressing and outputting refrigerant when the rotor 11 rotates. In order to prevent wear and pressure loss of the rotor 11 and the inner wall of the cylinder 10 due to friction between the rotor 11 and the inner wall of the cylinder 10, an elastic sealing member 20 is installed at a certain position on the corner of the triangular rotor 11.

[0021] The structure for preventing the wear of the Wankel compressor is described in detail below:

[0022] The structure for preventing Wankel type compressor 1a wear of the present invention is to prevent the wear caused by the friction between the rotor 11 and the inner wall of the cylinder 10, and the gap caused by the wear will cause refrigerant leakage and pressure los...

Abstract

The present invention relates to one antiwear structure for Wankle compressor. The Wankle compressor has triangular rotor, which moves eccentrically to change the spatial volume inside the cylinder to realize the strokes of sucking / compressing and expanding / exhausting refrigerant. The antiwear structure includes elastic sealing parts set in the edges of the rotor and can prevent the wear of both the rotor and the cylinder wall caused by friction as well as pressure loss and noise caused by wear and raise the performance of the compressor.

Description

technical field [0001] The invention relates to a Wankel compressor, in particular to a structure for preventing wear of the Wankel compressor. Background technique [0002] The Wankel compressor is a Wankel Rotary Engine invented by the German Felix Wankel, that is, when the outer gear of the main shaft and the inner gear of the rotor are connected, the eccentric triangular shape on the main shaft The rotor makes eccentric satellite motion around the main shaft, through the curve shape of the rotor and the epitrochoid (Epitrochoid: when a circle circumscribed on the circumference of a fixed circle rolls without slipping, it is drawn by a fixed point on the circle) The volume of the space between the cylinders changes, and the Wankel rotary engine structure changes in the whole process of suction / compression and expansion / exhaust when the main shaft 13 rotates, such as Figure 1a ~ Figure 1c As shown, the refrigerant flowing in from the suction port is compressed at high tem...
