  • Hydraulic system for a servo steering of a motor vehicle
    Patent number: 5127311
    Abstract: The hydraulic system for a servo steering of a motor vehicle, incorporates a main valve mechanism producing the assistance pressure (Pa) applied to a hydraulic assistance device (12) and including a pair of parallel fluid circuits between a source (14) of pressurized fluid and a reservoir (16), each fluid circuit comprising at least two restrictions (1,2,1',2') capable of being modulated by a rotor mechanism (10) cooperating with a stator mechanism (11), the junction point of the restrictions of each circuit being connected to a respective chamber of the hydraulic assistance device (12) and a secondary valve mechanism producing the reaction pressure (Pr) applied to the steering wheel shaft and including a second pair of parallel fluid circuits between a source (24) of pressurized fluid and a reservoir (16), each of the fluid circuits comprising at least two restrictions (3,4,3',4') capable of being modulated by the rotor mechanism (10) cooperating with stator means, the rotor mechanism (11) cooperating with t

  • Relief valve for hydraulic fluid
    Patent number: 5058618
    Abstract: The relief valve issued for controlling the pressure of a hydraulic fluid within a first duct 30 opening into a bore 14,16 provided in a body 10, a communication between the first duct 30 and a second duct 34 connecting a primary hydraulic circuit under pressure to the bore 14,16 being provided in rest position of a valve member when the pressure within the first duct 30 is lower than a threshold determined by the preload of resilient mechanism urging the valve member in rest position, the communication being interrupted when the pressure in the first duct 30 sensibly reaches the threshold. An increase of the pressure in the first duct beyond the threshold results in providing a communication between the first duct 30 and a third duct 38 connected to a low pressure circuit.
