Abstract
An improved side channel compressor wherein the compressor comprises first and second compressor stages each including first and second housing halves. In accordance with the invention, the inner housing halves (i.e., the second housing half of the first stage and the adjacently arranged first housing half of the second stage) are each provided with inlet and outlet openings of the same size and shape and with sealing rims surrounding these openings. In further accord with the invention, the second housing half of the first stage is provided with a further sealing rim arranged in the circumferential direction ahead of the outlet opening of that housing half and the first housing half with a further sealing rim arranged in the circumferential direction behind the inlet opening of that housing half. The further sealing rim of the second housing half is further arranged so that the distance between its center and the center of the outlet opening of that housing is equal to the distance between the centers of the rims surrounding the outlet and inlet openings of the housing half. Similarly, the further sealing rim of the first housing half is arranged so the distance between its center and the center of the inlet opening of that housing half is equal to the distance between the centers of the rims surrounding the inlet and outlet openings of the housing half.
