Abstract

Slide valve and coupling unit for flow control. This unit comprises a slide valve with a valve housing forming a first fluid flow passage, and a slide valve element guided for displacement between closed and open positions in relation to said passage. The unit also comprises a coupling element including a coupling housing which forms a second fluid flow passage to be connected to said first passage, and a recess to receive therein that portion of the valve housing which contains the slide valve element. When the valve housing is received with said portion in the recess of the coupling housing, the valve housing can be displaced in relation to the coupling housing while the slide valve element is retained in the recess, to a position wherein fluid flow connection is established through the passages.
