HYDRAULIC BRAKE SYSTEM FOR MOTOR VEHICLES |
摘要 |
A structurally simplified brake system which increases its functional reliability. The brake system has a brake pressure line extending between a master brake cylinder and a wheel brake. A shutoff valve is connected in parallel with a pressure limiting valve disposed in the brake line. A high-pressure pump toward the wheel brake side is capable of feeding pressure fluid into the line when the shutoff valve is closed. If a response pressure of the pressure limiting valve is exceeded, the pressure fluid can be diverted back to the master cylinder. The shutoff valve has a valve seat toward the wheel brake and a closing member toward the master cylinder which closing member is capable, by the action of a magnetic force on an armature of engaging the valve seat. A compression spring is disposed between the armature and the closing member and in the valve closing position exerts a closing force, adapted to the response pressure, upon the closing member. The shutoff valve and the pressure limiting valve are thus attained in a single valve unit.
