Abstract (en)
[origin: EP2295806A2] The device has two claw pistons (10, 11) shifting against each other in a cylinder housing (1). An air outlet opening (13) is provided with a cross section for obtaining a small geometrical compression ratio of a small internal compression. The claw pistons and/or shafts (14, 15) are provided with a fixed bearing (16) and a movable bearing (17). An axial distance between the bearings is smaller such that a claw compressor is inclined up to 45 degrees without the bearings with oil. The claw compressor exhibits a brushless permanent-moved synchronous motor (18) as a drive.
