Abstract: The hydraulic power control device comprises a boost piston whose movements depend on the pressure of fluid contained in an actuating chamber, said pressure being controlled by a distributing valve connected to a pressure fluid source and to a reservoir. The valve is operated by a push rod through the intermediary of a lever connected to a double sensor responsive to the relative movement of the valve and of the boost piston. The lever presents a first end on which the sensor is pivoted and a second end pivotably secured to a sliding pin mounted in housing of the control device.

Abstract: A device for regulating braking pressure, for example for controlling the rate of pressure rise in some of the brakes of a vehicle under varying load conditions of the vehicle. The device includes a pressure correcting valve adapted to be connected to the sprung part of the vehicle and a force transmitting mechanism adapted to be connected to the chassis. This mechanism is composed of two levers interconnected by draw springs. One of the levers, when at rest, engages an abutment fixed relative to the housing of the correcting valve. The other lever exerts a force on the movable member of the valve.

Abstract: The servomotor comprises a boost piston whose movements depend on the pressure of fluid contained in an actuating chamber, said pressure being controlled by a distributing valve connected to a pressure fluid source and to a reservoir. The valve is operated by a push rod through the intermediary of a lever assembly responsive to the relative movement of the push rod and of the boost piston. The push rod, mounted coaxially to said boost piston, projects therein. The projecting end contains a helical groove whose top cooperates slidably with the surface of a cylindrical bore formed in the boost piston.
