    Abstract: The invention relates to a metering type control unit for a power steering system. Units of this type most commonly utilize gerotor type gear sets for the metering operation. A problem with this unit is that highly pressurized fluid leaks from the expansible chambers formed between the star and ring members of the gerotor to the central bore of the star. Control units of this type require a universal drive between the rotatable valve thereof and the star which has a combination rotating and orbiting movement. In this invention the universal drive has a sealing flange associated therewith which serves to enclose the central bore of the star so that a fluid tight chamber is formed. Fluid is trapped in this central bore with the result that the pressure differential between the expansible chambers and this central bore is minimized and leakage is consequently minimized.

    Abstract translation: 本发明涉及一种用于动力转向系统的计量式控制单元。 这种类型的单元最常用于计量操作的齿轮齿轮组。 该单元的问题是高压流体从形成在转子的星形和环形构件之间的可膨胀室到星形的中心孔泄漏。 这种类型的控制单元需要在其可旋转阀和具有组合旋转和轨道运动的星形之间的通用驱动。 在本发明中，通用驱动器具有与其相关联的密封凸缘，其用于封闭星形的中心孔，从而形成流体密封室。 流体被捕获在该中心孔中，结果是可膨胀室与该中心孔之间的压力差最小化，从而使泄漏最小化。

    Abstract: The invention relates to a hydrostatic control unit for vehicle steering systems or the like. The unit has a gerotor-type metering motor, inlet and outlet ports and two motor ports which are connectable to a piston and cylinder-type motor of the kind used for actuating a vehicle steering linkage. The unit has changeover valve means having a neutral position and left and right operating positions relates to the two directions of rotation of the metering motor. The metering motor comprises ring and star members with the ring member being capable of only rotational movement and the star member being capable of only orbital movement. Commutator-type valve means is provided which has the form of a disc and is connected to the ring member for rotation therewith.

    CPC classification number: B62D5/097 ,  B62D5/093

    Abstract: THE INVENTION RELATES TO A HYDROSTATIC STEERING SYSTEM FOR HEAVY VEHICLES. THE SYSTEM COMPRISES DUAL UNITS IN SERIES WITH ONE UNIT BEING A WORKING UNIT AND THE OTHER UNIT BEING A CONTROL UNIT. EACH UNIT INCORPORATES CHANGEOVER AND SHUT-OFF VALVE MEANS AND METERING MEANS. A STEERING WHEEL ACTUATES THE CONTROL UNIT AND THE METERING MEANS OF THE CONTROL UNIT ACTUATES A CONTROL MOTOR WHICH IN TURN ACTUATES THE METERING MEANS OF THE WORKING UNIT. THE METERING MEANS OF THE WORKING UNIT ACTUATES A WORKING MOTOR CONNECTED TO THE STEERING LINKAGE OF THE VEHICLE.
