Title: HYDRAULIC FLOW RATE CONTROL DEVICE FOR A SYSTEM SUPPLYING HYDRAULIC LOADS, AND HYDRAULIC SYSTEM INCORPORATING SUCH A DEVICE
Abstract:
This hydraulic flow rate control device for a system supplying hydraulic loads with hydraulic fluid comprises a flow rate control member (16) that comprises a main body (17) in which are created a fluid inlet (E) and outlets (S1, S2, S3, S4) for supplying the loads, a stator (18) that is fixed with respect to the main body (17), and a set of rotors that are mounted in the stator and delimit, with the stator, at least one flow rate control chamber, each chamber being adapted to control the flow rate for one of the hydraulic loads, and comprising two compartments that are sealed with respect to one another and communicate with the inlet and with an outlet, the rotors being mounted on a common rotation spindle (20).
