Abstract

The valve limits the fluctuations in pressure in the system, having a pipe with a valve plate (11) with an opening (18) through it allowing flow in both directions. A cage (21) protrudes from one side of the plate round the opening, and on the other side there is a valve seat (29). A stationary valve spindle (37) mounted on the cage extends through the opening, and a valve disc (52) slides on the spindle and has one or more openings (53) in it, being spring-loaded clear of the seat against a stop (41), in which position flow can take place through the opening in the valve plate.
