    摘要： A multi-stage regulating valve is provided with a cylinder and an adjusting piston guided inside it to which a regulating pressure can be applied from one side and a return force from the other. Depending on the regulating pressure, the piston keeps at least one outlet aperture in the cylinder wall closed or partly or fully opens it and thus closes off a connection to the side of the piston to which the regulating pressure is applied or partly or fully opens it via the outlet aperture. To provide a multistage regulating valve which can alter the regulating characteristics over a wide range depending on the position of the piston even without the use of several return components, the piston consists of at least two partial pistons to which the regulating pressure can be applied, where the force of the return component can be applied to a first partial piston, whereby a follower interconnects the partial pistons in such a way that a return force is exerted on the second partial piston or other partial pistons via the first partial piston and the follower. The cylinder has at least one stop for the second or other partial pistons limiting the movement of the second or other partial pistons under the effect of the regulating pressure and against the action of the return component. The first partial piston is unaffected by the stop and remains movable against the return component if the regulating pressure increases further.

    摘要： A thrust washer (14) in the form of a semi-circular flanged ring includes at least two radially inward-directed outer connection pieces (22) on the inner edge of the thrust washer (14) for the connection with a radial bearing part (12), which are located in the circumferential direction on both sides of a contrived centerline (M) of the thrust washer (14) and in each case have an inner edge (23) facing the center line (M) and an outer edge (23a) turned away from the centerline (M). The invention also relates to a radio axial bearing with a radial bearing part and a thrust washer of such a type connected with the radial bearing part. The inner edges (23) in each case include an angle (α), which is 45° and 85°, with a tangent on the inner side connected in the center of the connection piece (22) at the semi-circle described by the thrust washer (14), in which the outer edge (23a) runs parallel to the respective inner edge (23). Such a thrust washer (14) can be connected with a radial-axial bearing (10) with a radial bearing part (12).
