Document Type and Number:
Japanese Patent JPH11508208
Kind Code:
A
Abstract:
A brake power booster for automotive vehicles includes a control valve that is operable by an electromagnet irrespective of an actuating rod displacing a valve piston, the electromagnet actuating a third sealing seat which permits ventilation of the working chamber. The valve member of the control valve has passages which allow a pneumatic pressure compensation. To eliminate a pneumatic force component which counteracts the force generated by the electromagnet, the passages are provided radially outside the area delimited by the electromagnetically operable sealing seat on the sealing surface of the valve member.
