The housing (1) has an intake socket (3) and a pressure socket (4) forming an inner passage channel, where the housing is made of glass fiber-injection molding. An inner wall (5) of the intake socket and the pressure socket has a material swelling (6) provided in form of a material application, which extends into interior of the channel. The material swelling intercepts circular shape of an inner cross section of the channel and forms a planar or concave inner surface, where the inner surface is parallel to a lateral flange surface (2), in which an electric motor is fastenable. |
