Abstract
An assembly for generating a negative pressure in an industrial process includes a plurality of interconnected units formed with wedge-shaped connections in their mutually contacting surfaces. Intermediate units in the assembly, such as an ejector housing, are formed in each contact surface thereof with the same type of connections. Accordingly, one end of the unit includes a female connection on one side thereof, and a male connection on the opposite side, whereas the other end of the unit includes a male connection on the first side and a female connection on the opposite side. The connections include inclined slide surfaces, providing a hook mount which presses the units together in a wedging effect as the units are axially displaced relative to each other. The displacement is produced by a bolt acting between the units.
