摘要： The pump for generating pressure or negative pressure comprises a pump chamber (32) which has a high-pressure port and a low-pressure port. Two rotors (28, 30) having at least two blades are fitted to two parallel shafts (20, 22) in the pump chamber (32) that are offset to each other, the shafts defining an axial direction. A drive (10) is arranged on an end face of the rotors (28, 30) and a housing cover (34) is arranged on the opposite side. The housing cover (34) is configured cup-shaped and the high-pressure port (42) as well as the low-pressure port (40) are integrated in the housing cover (34). The inner wall (44) of the housing cover (34) delimits the pump chamber (32) on an end face and has two axial openings (46, 48) one each adjoining by one channel (40, 42) which is integrated in the body of the housing cover (34). The axial opening (48) for the high-pressure port, in operation of the pump, is covered by one of the rotors (28, 30) for a time to enable inner compression of the delivered medium.

摘要： The compressor machine has two rotors rotating in opposite directions, which are fitted to two parallel, spaced apart shafts mounted in a housing. One of the shafts is driven directly and the other by intermeshing toothed gears mounted on the shafts. The housing has two radial walls which are configured in one piece with each other and with a peripheral wall and in which the shafts are mounted. The toothed gears are arranged between these radial walls. A side wall of the housing has an opening sealed by a removable cover. With the cover removed, the toothed gears can be fitted to the shafts through these openings. The bearing bores for the shafts can be produced and machined in the one-piece housing in a single set-up, so that, with a minimum number of parts, any causes of alignment errors are avoided.
