Embodiment Construction

[0034] Below in conjunction with specific embodiment, content of the present invention is described in further detail:

[0035] In order to achieve the purpose of the present invention, a sealing structure of an automobile compressor includes: a pressure plate 1 assembled with the body 3 of the compressor; an annular groove including a first annular groove 6 on the pressure plate 1 and a first annular groove 6 on the body 3 Two annular grooves 7, the cross-sectional profiles of the first annular groove 6 and the second annular groove 7 are square-shaped and their own length is circular; the sealing ring 4 is located in the annular groove, and the first annular groove 6 and the second annular groove 7 The depth and not less than the circle diameter of sealing ring 4 cross section.

[0036] The circles corresponding to the width centers of the first annular groove 6 and the second annular groove 7 are equal.

[0037] The beneficial effect of adopting the above-mentioned technic...

Abstract

The invention discloses a sealing structure of an automobile compressor. The sealing structure comprises a pressing plate, annular grooves, and a sealing ring; the pressing plate and a machine body ofthe compressor are assembled together; the annular grooves comprise the first annular groove and the second annular groove, wherein the first annular groove is formed in the pressing plate, the second annular groove is formed in the machine body, the outlines of the cross sections of the first annular groove and the second annular groove are in a u shape, and are circular in the length direction;and the sealing ring is positioned in the annular grooves, the total of the depth of the first annular groove and the depth of the second annular groove is not smaller than the circular diameter of the cross section of the sealing ring. The sealing structure is adopted, a sealing path is prolonged, the sealing path is also bent from being straight, the inside and outside environments of the compressor are further isolated; and meanwhile, too large pressure is not generated on the sealing ring while the sealing ring is fixed, and thus the service life of the sealing ring is prolonged.

Description

technical field [0001] The invention relates to the field of automobile air-conditioning compressors, in particular to a sealing structure of an automobile compressor. Background technique [0002] Automobile air-conditioning compressor is the heart of automobile air-conditioning refrigeration system, which plays the role of compressing and transporting refrigerant vapor. After the existing compressor is manufactured and assembled until the compressor leaves the factory, the pressure plate used for sealing is in contact with the rubber sealing ring under force for a long time, resulting in deformation of the rubber sealing ring. figure 1 An existing common automotive air-conditioning compressor shown in , which has two positions where the sealing ring is used. Such as figure 2 As shown in , the sealing ring is located in the groove, and the flat surface of the pressure plate squeezes the sealing ring to completely compress the sealing ring in the groove. If things go on l...
