Housing for a side channel compressor

#The invention relates to a housing consisting of two housing halves for a side channel compressor.

#Such a housing is known from DE-U-92 15 231. In that housing, the housing halves consist of metal, for example aluminum, and therefore have sufficient strength.

#The object on which the invention is based is to design the housing of a side channel compressor in such a way that, when it is produced from a material, for example plastic, having lower strength than metal, it can withstand the loads which occur during operation.

#FIG. 1 shows a top view of a housing half of a side channel compressor housing, and

#FIG. 2 shows the two housing halves of a side channel compressor housing in section along the line II--II in FIG. 1.

#The two housing halves of a side channel compressor housing are designated by reference numerals 1 and 2. A first and second ring 4 and 5 are formed on the front wall 3 of each housing half. The rings 4 and 5 project axially relative to the front wall 3 and are spaced radially from one another. The radius of the first ring 4 corresponds approximately to the outer radius of the side channel 6 formed in each housing half 1 and 2 and the radius of the second ring corresponds approximately to the inner radius of the side channel 6.

#Between the first and second ring 4 and 5, rib walls 7 extending in a spoke-like manner are formed on the outside of the wall part 8 constituting the side channel 6. These rib walls 7 appreciably increase, in particular, the strength of this wall part 8 which is subjected particularly severely to the compression pressure.

#A centering ring 9 is provided on the front wall 3 of each housing half 1 and 2 located concentrically relative to the two rings 4 and 5 and radially further inward. Formed in the region between this centering ring 9 and the adjacent second ring 5 are further rib walls 10 which are arranged in a manner staggered relative to the rib walls 7 extending between the first and second ring 4 and 5. The load forces are thereby also introduced into the second ring 5 which thus contributes to an increase in strength.
