Abstract
The invention relates to a hydraulic power booster, in particular for the actuation of a master cylinder in a hydraulic brake system for motor vehicles. The booster comprises a pressure fluid source, a control device for the control of the pressure level in a booster pressure chamber, an actuating element for the actuation of the control device which actuating element is acted upon by an input force, a converting device for the conversion of the hydraulic pressure into a translatory force which converting device is acted upon by a pressure fluid, and a force transmission element which, preferably is an operating rod for a tandem master cylinder. A semi-rigid force transmission element is arranged in the structure for the transmission of force from the actuating element to the force transmission element in order to obtain a two-stage effect.
