    摘要： A hydraulic positioner for maintaining a given separation between its attachment points and having a bidirectional detenting action whereby the given separation can be altered only by application of a sufficiently large overriding force. A closed cylinder is divided into two closed fluid-filled chambers by a slidable piston. Motion of the piston requires transfer of fluid between the chambers. The transfer flow is determined by preloaded check valves in the transfer flow path. The check valves are preloaded in opposite directions to achieve the bidirectional detenting action. A reservoir supplies fluid under a small positive pressure to one of the closed fluid-filled chambers to replace fluid lost through leakage.

    摘要： An installation for the automatic control of the light projection distance of motor vehicle headlights in dependence on the positional change of the vehicle body, in which in case of a positional change of the vehicle body toward one side when driving through a curve, an analogous control of the light projection distance of the headlight takes place in such a manner that, for example, with right-hand traffic and when driving through a right-hand curve, the light projection distance is decreased and vice versa is increased in a left-hand curve.
