<p>The assembly for generating a negative pressure in an industrial process according to the invention is characterized in that the interconnected units (1, 2, 3..) are formed with wedge-shaped connections (13, 14) in their mutually contacting surfaces. Intermediate units in the assembly, such as the ejector housing (2) of the drawing, are formed in each contact surface thereof with the same type of connections: accordingly, in one end the unit comprises a female connection (14) on one side thereof, and a male connection (13) on the opposite side, whereas the other end of the unit comprises a male connection on the first said side and a female connection on the opposite side. The connections comprise inclined slide surfaces (11, 12), 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 being produced by means of a bolt (10) acting between the units.</p> |
