    Abstract: The invention concerns a method of producing concave, self-contained bearing surfaces, which are at least part of universal ball joints extending over the ball equator, by machining depressions pre-formed in workpieces by means of a tool having a cutting edge rotating about a rotational axis of said tool, the trajectory having a diameter which is equal to the length of a chord extending to the lowest point of the bearing surface. The cutting movement is composed of the rotary movement of the tool cutting edge and a rotating relative movement between the workpiece and tool about a vertical axis through the centre point of the ball. The feed movement is a relative movement of the tool to the workpiece along the axis of rotation of the tool inclined at the same angle of inclination relative to the vertical axis as the chord to the ball equator. In order to decrease production times and increase the dimensional accuracy of the bearing surface, the invention proposes that the chord (S) originates from the ball equator (A) and the depressed areas on both sides of the ball equator (A) be machined with two separate feed movements. The invention further concerns a bearing surface as a product of this method.

    Abstract: The invention concerns a power- and moment-regulating system for at least two adjustable hydraulic pumps (10, 11), said system comprising for each hydraulic pump (10, 11) a hydraulic servo control apparatus (22, 23) for continuously adjusting the delivery. To that end, the delivery of each hydraulic pump (10, 11) is determined as a function of the delivery pressure of the respective hydraulic pump (10, 11) in a delivery pressure line (16, 17) associated with the hydraulic pump (10, 11) and the control pressures in control lines (20, 21) provided for each hydraulic pump (10, 11). Each servo control apparatus (22, 23) is provided with a moment valve (42, 43) having a valve piston (62) which can move in a valve sleeve (61) and forms a valve seat with the latter and whose closure force is determined by a measuring spring arrangement (46, 47) which is connected to the pump actuator (37, 38) and is pretensioned as a function of the set delivery. To that end, each moment valve (42; 43) connects the control line (20, 21) of the associated hydraulic pump (10; 11) to an outlet (41) as a function of the control pressure in this control line (20; 21) and the control pressure in the control line (21; 20), that is the control pressures in the control lines of the other hydraulic pump(s) (11; 10) in each case, under the pretension of the measuring spring arrangement (46; 47). According to the claimed development, for a given hydraulic pump (10; 11), the control pressure in the control line (21; 20) or the control pressures in the control lines of the other hydraulic pump(s) (11; 10) in each case act both on the valve piston (62) and on the valve sleeve (61) of the moment valve (42; 43) associated with the given hydraulic pump (10; 11).

    Abstract: The present invention pertains to a dual-function hydraulic valve (1), i.e. a control valve and a pressure reduction or limitation valve at the same time. The inventive combined hydraulic valve (1) encompasses a valve casing (2) with a first central pressure connection (P), a second central pressure connection (Br) and a movable flow check piston (7) in the valve casing (2). The flow check piston (7) presents a pressure surface (16) enabling it (P), when the first central connection is put under supply pressure (Pp), to move from its basic position against an opposing force proportional to said supply pressure (pp). It also presents a first control ridge (40) and a second control ridge (41). The first control ridge (40) is used to link the first central pressure connection (P) to the second central pressure connection (Br), starting from a first set minimum displacement of the flow check piston (7) which corresponds to a lower threshold value (p1) of the supply pressure (pp). The second control ridge (41) is used to break the linkage of the first (P) central pressure connection with both the second central pressure connection (Br) and the pressure surface (16), starting from a set maximum displacement (7) which corresponds to a higher threshold value (p2) of the supply pressure (pp).

    Abstract: A device is disclosed for regulating the output of at least one variable displacement pump (1) driven by a motor (6) and forcing a medium into a working line. This is done by altering the displaced volume of the pump by means of an adjusting device (7) to which an adjusting pressure (20) can be applied and which is biased in the direction of maximum displaced volume. The proposed device has a control valve (18) allocated to the adjusting device (7). The control valve can be subjected to a counter-pressure corresponding to the operating pressure in the operating line, the control valve (18) responding when the control pressure exceeds the counter-pressure, and the adjusting device (7) is acted on by the adjusting pressure to effect a reduction in the displaced volume of the variable displacement pump (1) in such a way that the product of operating pressure and displacement volume is constant. A device (25) is provided to determine the position of the adjusting device (7) and send a position signal proportional to that position to an electronic control unit (40). Also provided is a pressure limiting valve (42) by which the maximum counter-pressure in the control valve (18) can be set. The electronic control unit (40) controls the pressure limiting valve (42) in accordance with the position signal from the position sensor (25). Also disclosed is a method of controlling the output of a variable displacement pump (1) driven by a motor (6) and forcing a medium into an operating line.

    Abstract: The invention concerns an axial piston machine (1) which comprises a cylinder block (2) having cylinder bores (3, 4) in which pistons (5, 6) are movably guided, said pistons (5, 6) being supported on an inclined or wobble plate (25) in order to perform a lifting movement. The axial piston machine (1) further comprises a pivot device (31) for varying the inclination of the inclined or wobble plate (25) by pivoting about a pivot axis (27). The development according to the invention is provided with a damping element (41) which comprises a damping piston (40) which acts on the inclined or wobble plate (25) and is movably disposed in a damping cylinder (42) which is connected to a pressure fluid reservoir (48) via a throttle element (47) and a non-return valve (44) disposed parallel thereto. The non-return valve (44) enables pressure fluid to flow in an unthrottled manner from the pressure fluid reservoir (48) into the damping cylinder (42) and prevents the pressure fluid from flowing out of the damping cylinder (42) in an unthrottled manner by bypassing the throttle element (47). In this way, a damped pivot movement of the inclined or wobble plate (25) is brought about.
