Embodiment Construction

[0066] figure 1 A prior art scroll compressor 1 is shown in cross section. A scroll compressor 1 includes a housing 2; an immovable fixed stator 3 having a disk-shaped base plate 3a and a wall 3b extending from one side of the base plate 3a formed in a spiral shape; The movable scroll 4 is formed with a wall 4b extending from the front side of the base plate 4a. The non-movable or fixed helical part 3 or the movable helical part 4 is also referred to simply as the stator 3 and the movable scroll 4 cooperation, respectively. Here, the base plates 3 a , 4 a are arranged opposite each other such that the walls 3 b of the stator 3 and the walls 4 b 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 helix 4, the walls 3b, 4b contact at several locations and within the walls 3b, 4b are formed several sequentially closed working volumes 5, wherein adjacently arranged working volumes 5 delimit...

Abstract

The present invention relates to a method for manufacturing a scroll compressor (1) and, particularly, to a pretreatment method for coating regions of a scroll compressor (1), which come into contactwith each other during operation of the scroll compressor (1). The scroll compressor (1) comprises: a fixed scroll (3) including a base plate (3a) and a scroll-shaped wall (3b) extending from one sideof the base plate (3a); and an orbiting scroll (4) including a base plate (4a) and a scroll-shaped wall (4b) extending from the front side of the base plate (4a). The scrolls (3, 4) are formed of a 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, having at least one region pretreated and coated according to the method of manufacturing a scroll compressor. Background technique [0002] In climate control systems known in the prior art for mobile applications, in particular for motor vehicles, the compressor for delivering the refrigerant through the refrigerant cycle (also called refrigerant compressor) is often independent of the refrigerant Formed as a piston compressor with variable stroke displacement or as a scroll compressor. The compressor is here driven via a pulley or electrically. [0003] Conventional scroll compressors for refrigerants such as R...
