Integrated pressure generating and control device

Claim 1

A hydraulic wheel-braking device, for one of wheel anti-lock and anti-slip functions in a brake circuit of a vehicle, comprising, between a chamber of a master cylinder and at least one brake motor, a plurality of solenoid valves and a hydraulic pump driven by an electric motor including a rotor arranged between two bearings and enclosed in a cylindrical sleeve made of metallic material, said rotor driving in rotation an eccentric cam imparting an alternating translational movement to radial pistons, a delivery outlet of said pump being connected to said solenoid valves via hydraulic slides by means of fluid circulation channels, characterized in that said sleeve, in which the rotor is accommodated, is enclosed in a housing made of nonmagnetic material, the fluid circulation channels and the solenoid valves extending in said housing along longitudinal axes substantially parallel to the longitudinal axis of the rotor of said motor, electrical connections of said solenoid valves being substantially in the same radial plane and substantially adjacent to a plane containing electrical connections of said motor, and a first of said bearings included in a first cover closing one radial end of said housing and containing electrical control circuits of said solenoid valves and of said motor.
