Embodiment Construction

[0066] figure 1 A prior art scroll compressor 1 is shown in a cross-sectional view. The scroll compressor 1 includes a casing 2; an immovable stationary stator 3 having a disk-shaped base plate 3a and a wall 3b formed in a spiral shape extending from one side of the base plate 3a; The movable orbiting scroll 4 is formed in the shape of a wall 4b extending from the front side of the base plate 4a. Also referred to simply as stator 3 and orbiting scroll 4 cooperating as immovable or fixed helical part 3 or movable helical part 4 , respectively. Here, the base plates 3a, 4a are arranged opposite to each other such that the walls 3b of the stator 3 and the walls 4b of the orbiting scroll 4 are staggered. The movable helix 4 is moved along a circular path by an eccentric drive. During the movement of the helical portion 4, the walls 3b, 4b contact at several locations and within the walls 3b, 4b are formed several sequentially closed working volumes 5, wherein the adjacently arr...

Abstract

The present invention relates to a method for manufacturing a scroll compressor (1) and, in particular, to a pretreatment method for coating the area of ​​the scroll compressor (1), said area in the scroll compressor (1) contact each other during operation. The scroll compressor (1) comprises: a fixed scroll (3) comprising a base plate (3a) and a scroll-shaped wall (3b) extending from one side of the base plate (3a); and comprising a base plate (4a) and an orbiting scroll (4) of a scroll-shaped wall (4b) extending from the front side of the base plate (4a). The scrolls (3, 4) are formed from the base material.

Description

technical field [0001] The present invention relates to a method of manufacturing a scroll compressor, in particular a method for coating pretreatment of areas that come into contact with each other during operation of the scroll compressor. The invention also relates to a scroll compressor as a device for compressing a gaseous fluid, in particular a refrigerant, with at least one zone pretreated and coated according to the method of manufacturing a scroll compressor. Background technique [0002] In climate control systems known in the art for mobile applications, especially for motor vehicles, the compressors used to deliver the refrigerant through the refrigerant cycle (also called refrigerant compressors) are often independent of the refrigerant It is formed as a piston compressor with variable stroke displacement or as a scroll compressor. The compressor is driven here by means of a pulley or electrically. [0003] Conventional scroll compressors for refrigerants such...
