摘要： To provide a particularly simple and cost effective design of a power-assisted steering unit for motor vehicles for supplying a servo-cylinder (3) with a hydraulic fluid as a function of the travelling speed and the steering rate, comprising a steering valve (1) by means of which the left and right chambers (16, 17) of the servo-cylinder (3) can be pressurized with hydraulic fluid via a pump (2) when there is a steering movement, and a bypass valve (10) connected in parallel to the servo-cylinder (3), by means of which a portion of the hydraulic fluid for pressurizing the servo-cylinder (3) that is directed past the servo-cylinder (3) is controlled, a throttling unit (26) is connected in series with the bypass valve (10). The hydraulic fluid inflow or return flow of the servo-cylinder (3) flows through this throttling unit (26) depending on the steering direction. The throttling unit (26) automatically throttles the flow of hydraulic fluid that is directed through the bypass valve (10) starting from a predetermined value of such volume flow.Furthermore defined is an assisted-power unit for motor vehicles for supplying hydraulic fluids to a servo-cylinder (3) as a function of the travelling speed, wherein the bypass valve (10) is designed as a proportional valve to achieve a particularly compact and cost effective form of construction.

摘要： A steering valve (1) for supplying an actuator with hydraulic pressure, consists of an input shaft (2), an output shaft (3), a torque rod (4), connected at one end to the input shaft (2) and at the other end to the output shaft (3), and a valve sleeve (5) surrounding the input shaft (2). A torsionally resistant, axially elastic element (9) is contained within the steering valve (1), connected at one end to the input shaft (2) and at the other end to a catch device (10). The catch device (10) ensures no relative displacement between the valve sleeve (5) and the input shaft (2); prior to a predetermined degree of torque, and converts the torque acting upon the input shaft (2) to axial forces acting upon the elastic element (9) until a release position is reached. The elastic element (9) is mounted on the input shaft (2) by means of a bearing sleeve (11), which is fixed in an axial position on the input shaft (2).
