摘要： With a steering wheel steered to the left, a control valve connects a first cylinder port A to a pump port P and connects a second cylinder port B to a discharge port T, and with the steering wheel steered to the right, the control valve connects the first cylinder port A to the discharge port T and connects the second cylinder port B to the pump port P. When the control valve is at a neutral position, the pump port P is connected to the first cylinder port A and to the second cylinder port B and the discharge port T is isolated from the pump port P, the first cylinder port A, and the second cylinder port B.

摘要： Ein Elektro-Hydraulisches Lenksystem ist mit einer Eingangswelle (1), mit einem Drehschieber (2), einer Abtriebswelle (4), einer Torsionsfeder (3) zwischen dem Drehschieber (2) und der Abtriebswelle (4), einer mit der Abtriebswelle (4) verbundenen Ventilbuchse (5), einer in die Ventilbuchse (5) mündenden Druckmittelzulauf (6) und einem Druckmittelrücklauf (7) zwischen der Abtriebswelle (4) und dem Drehschieber (2) versehen. In dem Druckmittelrücklauf (7) ist zwischen der Abtriebswelle (4) und dem Drehschieber (2) ein Kolben (8) angeordnet. Der Kolben (8) ist auf einer Seite verdrehfest, aber axial verschiebbar in der Abtriebswelle (4) fixiert und auf der anderen Seite mit einem Mitnahmeprofil (10) zum Drehschieber (2) versehen. Ein Schließglied (13) bewirkt eine in Richtung auf den Druckmittelzulauf (6) wirkende Schließkraft auf den Kolben (8), die kleiner ist als die Druckkraft auf den Kolben (8) bei Druckmittelzufuhr über den Druckmittelzulauf (6) zur Zuschaltung der Hydraulik.
摘要翻译：电动液压转向系统包括设置在驱动轴（4）和旋转滑块（2）之间的压力返回（7）中的活塞并固定成在驱动轴中轴向滑动的活塞。活塞在一侧弯曲并且设置有用于另一侧的旋转滑块的卡形轮廓（10）。当液压系统关闭时，关闭部分（13）产生作用在压力返回上的闭合力，该压力小于通过压力回送的压力进给时活塞上的压力。优选特征：活塞在外周弯曲，但轴向连接到驱动轴上。止动轮廓形成在活塞的前侧或内周壁上。

摘要： The rotation conversion mechanism (50, 50', 150) in a power steering apparatus converts the relative rotation between input and output shafts (2, 102, 3, 103) connected by a torsion bar (6, 106) into relative rotation between a first rotating element (31, 111) and a second rotating element (32, 112). The ratio of the latter relative rotation angle to the former relative rotation angle is set as an invariable fixed value. An actuator (20, 120) is controlled by a control mechanism (30, 131) so that steering assist force which corresponds to the relative rotation angle between the two rotating elements (31, 111, 32, 112) is generated. When the relative rotation of the input shaft (2, 102) to the output shaft (3, 103) is converted into relative rotation of the first rotating element (31, 111) to the output shaft (3, 103), the direction of rotation is reversed by a reversing element (54, 54', 154).

摘要： A method for machining an angularly disposed array of parallel longitudinally extending slots in a bore of a component, the method comprising the steps of: gripping said component (1) in a gripping means of a workholding device (2) mounted to a workholding spindle (3) indexable about a first axis; cutting said array of slots in said bore by a series of progressively deeper cutting strokes of a cutting tool (5), said tool mounted to a cutting spindle (7) rotatable about a second axis (8) substantially at right angles to and offset from said first axis; and the cutting of each slot followed by indexation of said workholding spindle (3); and during the cutting of at least one of said slots, relative movement between the component (1) and second axis (8) takes place due to movement of the component (1) along the first axis or movement of the second axis in a direction substantially parallel to said first axis or both. A one piece sleeve (34) for a rotary valve (31), the sleeve (34) comprising an array of inlet (26) and return (27) slots formed in the bore of the sleeve, the inlet slots (26) being stopped short of the axial extremities of the bore, the return slots (27) extending to one extremity of the bore providing an exit area for return oil when the sleeve is installed in the rotary valve, characterised in that at least one said return slot is also extended to the other axial extremity of the sleeve bore providing an entry area (24) for leakage oil when the sleeve is installed in the rotary valve, the entry area (24) provided for leakage oil being substantially smaller than the exit area provided for return oil.

摘要： A classifying storage of the respectively measured, actual valve characteristic curves is provided for a hydraulic servo-assisted steering system for motor vehicles and, corresponding to these valve characteristic curves, flow characteristic curves are prepared for the magnetic actuator of the converter (9), which can be classified in pairs in order to compensate for variations from a predetermined set valve characteristic curve. The invention also provides a testing method for a hydraulic servo-assisted steering system of this type, according to which the actuating pressure of the servo actuator is influenced according to a steering input torque and in a speed-dependent manner. The speed-dependent influence is effected by the electro-hydraulic converter (9) whose flow can be controlled with regard to the correction of tolerances in a manner that is superimposed with regard to the speed-dependent determination.
