Abstract
A liquid-regulating valve comprises a cylinder tube (6) having holes (7) through which liquid can pass in radial jets. Further, the valve comprises a piston (9) and a distributing means (15) which is fixedly mounted in the cylinder-tube (6) and consists of several radial walls (16) upon which impinge the liquid jets entering through the cylinder tube holes (7) to be disintegrated and divided into part flows. At one end, the distributing means (15) has a cover plate (20) which, at the periphery, merges into an annular flange (21) projecting axially from the plate and serving to divert and guide the liquid part flows that, after impinging upon the radial walls of the distributing means, are directed towards the cover plate (20) and follow the plate along a substantially axial path of motion.
