Abstract

A plunge valve for closing and for opening a connection in a hydraulic conduit comprises a plunge (37) which is slidably movable in the hydraulic conduit (5, 5A) under the influence of the pressure in a section (5A) of the conduit on the inlet side of said conduit adjacent to the plunge between a first, open position, when the pressure in said section (5A) is high, in which position the plunge is withdrawn and communication is established, and a second, closed position, in which the pressure in said section is low, in which position the plunge shuts off said connection.
