摘要： The control arrangement may be used for vehicles or in other steering systems and includes a steering motor that is adjusted as a function of hand operated steering mechanism, the steering mechanism controlling a directional section and a metering motor section. The directional section is fluidly connected between the steering motor and both of a tank and the metering motor section. A pump is connected between a tank and the metering motor section. The one sides of electromagnetic plus and negative valves are fluidly connected between the fluid connection of the metering motor section and the directional section while the opposite sides are respectively connected to the connection of the pump and the metering motor section and the connection of the directional section to the tank. A processing device for controlling the valves is provided for sensing the steering angle error. The control arrangement provides a simple structural arrangement to compensate for leakage.

摘要： The invention relates to a hydrostatic control device for steering unit device which includes a metering motor and a flat slide directional valve. Slide surfaces of the directional valve are formed by the abutting end faces of an outer housing and a motor housing and between the two slide surfaces there is formed a high pressure zone. Between two end faces of the outer housing and the motor housing opposite thereto is an intermediate pressure zone of larger area which is connected between a first throttle gap associated with the high pressure zone and a second throttle gap leading to the low pressure zone. With the aid of the high pressure zone and the intermediate pressure zone equilibrium can be obtained while incurring only a minimum amount of friction.

摘要： The invention relates to a hydrostatic steering control unit of the type having a metering motor for supplying metered pressurized fluid to external servomotor. The unit has a throttled controlled passage which bypasses the metering motor and has a flow therethrough which has a definite relationship to the flow through the metering motor. In this way a comparatively large amount of pressure fluid can be supplied to the servomotor even though the flow capacity of the metering motor is much smaller.

摘要： A gear wheel assembly of the type having an externally toothed gear wheel and an internally toothed ring wheel with the gear wheel having one less tooth than the ring wheel and the wheels having eccentrically spaced axes with said gear wheel being rotatable about the gear wheel axis which in turn is orbitable about the ring wheel axis. Each tooth of the gear wheel has a flank on each side of the tip thereof with each said flank having a shallow recess formed thereon. Each such recess has three successive curved sections with each such recess starting and ending with the same tangent as the respective adjacent part of the associated flank. With this gear construction an automatic braking action is generated in the absence of hydraulic pressure.

摘要： A hydraulic machine is disclosed, having an annular gear with internal teeth and a gearwheel with external teeth mounted eccentrically therein, the internal teeth comprising one more tooth than the external teeth and the teeth of at least one set of teeth being formed by rotatably mounted rollers. It is desirable in such a machine for the internal seal to be improved and wear to be reduced. To that end, each roller has in its surface at least three axially parallel recesses, in which the teeth of the other set of teeth engage.

摘要： The invention relates to a fluid pressure operated motor or pump of the type having a gerotor displacement mechanism which normally includes inner and outer wheel and ring gears which in operation have relative rotational and orbital movement therebetween. Such devices inherently have a form of valving wherein, with a commutating type of action, fluid is directed from the casing inlet to expanding chambers of the gerotor and directed from collapsing gerotor chambers to the casing outlet. Two embodiments are presented in which the first has the casing thereof fixed in space. In both units the commutator valving includes valving patterns in two valve plates attached to opposite sides of the casing and in the wheel gear which has orbital movement relative to the casing. The commutating valving arrangement has control ports on opposite sides of the unit for feeding and exhausting motive fluid to and from the unit and auxiliary ports on opposite sides of the unit to balance or equalize the pressure forces on each side thereof. Bolts are used for fastening the tightening together the casing side plates. These bolts are also used as guides for the orbital path of the ring gear and holes are provided in the ring gear to accommodate the bolts.
