    摘要: A leveling control mechanism for motor vehicles includes an electric pump and a solenoid valve for raising and lowering the vehicle body and a leveling switch with an electronic damping device. The periodic measurement of the distance from the vehicle axle to the vehicle body is carried out by a mechanical-electrical converter, which converts the rotation of a shaft into an electrical signal. During acceleration and deceleration of the vehicle, as well as during the occurrence of centrifugal forces, suitably situated inertial switches inhibit the response of the leveling control mechanism.

    摘要: A dual circuit brake valve which is provided with a relief connection intended for two separate individual valves and in which two outlet valve seats are disposed centrally in the valve. The two outlet valve seats are prestressed with respect to one another by way of a bolt and a prestressed pressure-limiting spring in such a way that at a time braking begins the two individual valves represent a rigid connection. From a pressure limitation point on, the two individual valves then support themselves elastically against one another, so that a further increase in braking pressure is precluded. The dual circuit brake valve is intended for brake systems having high pressure as a reservoir pressure and normal pressure as the braking pressure.
