Abstract

The hydraulic liquid flow regulating valve has a constriction of constant section inserted in the liquid circulation path. A principal piston with a movable constriction is also fitted in the liquid circulation path. One of the faces of the piston is submitted to a spring force whilst the other face is connected to a discharge orifice. The valves output orifice has a control channel which connects with the cylinder of a discharge valve. The discharge valve consists of an auxiliary piston one face of which acts against an auxiliary spring force and the resultant force of the valves output pressure. The force exerted by the spring being approx. constant.
