Abstract
An improved side channel compressor wherein the compressor has a side channel with inlet and outlet openings and a rib projecting in the axial direction into the channel and wherein the improvement comprises providing that the rib have a height which is from 10 to 25 percent of the depth of the side channel and arranging the rib approximately mid-way between the inlet and outlet openings.
Claims4
In a side channel compressor of the type having a side channel within an inlet and outlet opening and at least one rib projecting into the side channel in the axial direction of the compressor, the improvement comprising:
- said rib having a substantially triangular cross section and being arranged in a direction substantially transverse to said side channel approximately mid-way between said inlet and outlet openings and having a height which is approximately 10 to 25% of the depth of said side channel, whereby cavity resonances in the side channel are substantially attenuated.
In a side channel compressor of the type having a side channel within an inlet and outlet opening and at least one rib projecting into the side channel in the axial direction of the compressor, the improvement comprising:
- said rib extending in the meridian plane of said side channel compressor and being arranged in a direction substantially transverse to said side channel exactly mid-way between said inlet and outlet openings and having a height which is approximately 10 to 25% of the depth of said side channel, whereby cavity resonances in the side channel are substantially attenuated.
