Abstract
A pressure regulator for an automotive hydraulic braking system includes a housing provided with at least one pressure fluid inlet and one pressure fluid outlet with a connection between the inlet and outlet controlled by a valve unit driven by a driving force in proportion to an application force. The pressure regulator is substantially located in the interior of a suspension spring of a vehicle. To attain a load-sensitive pressure regulator of high precision, there is provided a fluid enclosed by a membrane which serves to transform the application force to the valve driving force. The driving force is applied to the pressure regulator valve unit through a partial face of the membrane in an opening direction of the valve.
