ABSTRACT:
The invention relates to a pressure-regulating valve with slide valve, comprising three decreasingly pressurized enclosures: an admission chamber, a discharge chamber and a return chamber. Said valve comprises means for creating a communication, in the intermediate position of the slide valve, between the discharge chamber and the return chamber, which means constitute a restriction whose dimensions are selected so that the fluid flowing therethrough is equal to the maximum value of the flow of fluid between the admission chamber and the discharge chamber. The present invention finds an application in the production of a stable hydraulic handling machine.
