The ejector comprises a cylindrical body for mounting in an opening in a seat with a cylindrical wall so that the inlet end of the body is inserted into the seat and the outlet end protrudes from the seat opening. The body has a region with a radius which increases in the inlet end direction over a certain axial distance and this region is located between the inlet and outlet ends. The body includes a stop at its outlet end which presents a support surface facing in the direction of the increasing radius region. A cylindrical mounting sleeve is secured around the body and can be moved axially between the stop and increasing radius region. The sleeve includes a wall which can be expanded in the radial direction of the sleeve in order to clamp the sleeve between the body and seat. An independent claim is also included for a method for mounting a compressed air-driven vacuum pump in a seat with a circular cross-section. |
