Abstract: A valve (10) for the temperature-dependent control of at least one hydraulic load includes a valve housing (12) with a tank connection (T), a working connection (A), and a supply connection (P). A control piston (30) controls the connections (A, P, T), is moveable in the valve housing (12) and is preloaded by a working spring (74). A thermal element (62) can be supplied with a fluid at a specifiable temperature (TFIuid) and is actively coupled to the control piston (30). The control piston can be moved by control pressure present at the supply connection (P). The thermal element (62) interacts with the working spring (74) such that the thermal element causes a temperature-dependent change of the preload force acting on the control piston (30).

Abstract: An axial piston pump has a swash-plate construction, in particular for hydraulic systems. A cylinder drum (3) can be rotationally driven about a rotational axis (7) in a pump housing (1). Pistons (9) are axially displaceable and support at their actuation ends a swash plate (15). The swash plate can be pivoted by an adjusting device (21) to the desired angles of inclination relative to the rotational axis (7) for adjusting the stroke of the pistons (9) and the fluid pressure generated. The adjusting device has an adjusting piston (35) in a hydraulically actuated adjusting cylinder (31). Their movement can be transmitted to the swash plate (15) by a driven connection having a pivot joint (37, 39; 29, 43). The pivot joint is formed by a ball joint (37, 39) arranged between the piston (35) and the piston rod (41) of the adjusting cylinder (31).

Abstract: The invention relates to an axial piston pump having a swash-plate type construction, in particular for hydraulic systems, comprising a cylinder drum (3) which can be rotationally driven about a rotational axis (7) in a pump housing (1) and in which pistons (9) are arranged in an axially displaceable manner, supporting by means of the actuation end thereof (11) which is accessible from the outside of the cylinder drum (3), at least indirectly a awash plate (15), said swash plate can be pivoted by means of an adjusting device (21) to the desired angles of inclination with respect to the rotational axis (7) for adjusting, the stroke, of the piston (9) and also the fluid system pressure generated thereby.

Said swash plate (3) is mounted, for the pivotable movements thereof, on the pump housing (7) by means of a swash plate bearing (39, 41); characterized in that a supply device (5), which enables a fluid which is at a system pressure to travel at least to the swash plate bearing (39, 41), is provided.

Abstract: The invention relates to a valve (10) for the temperature-dependent control of at least one hydraulic load, comprising a valve housing (12), which has at least one tank connection (T), one working connection (A), and one supply connection (P), a control piston (30) for controlling the connections (A, P, T), which control piston is movably arranged in the valve housing (12) and is preloaded by an energy store, such as a working spring (74), and a thermal element (62), which can be supplied with a fluid at a specifiable temperature (TFluid) and which is actively coupled to the control piston (30), wherein the control piston can be moved by control pressure present at the supply connection (P) and wherein the thermal element (62) interacts with the energy store (74) in such a way that the thermal element causes a temperature-dependent change of the preload force acting on the control piston (30).

Abstract: A mobile interface for controlling a plurality of vehicle functions in a motor vehicle using a controller connected to the vehicle, having a wireless data interchange with a controller, an input apparatus, and an energy store. By virtue of the wireless data interchange being connected to a data processing unit integrated in the mobile interface and which is designed to apply at least one cryptological method, a greater scope of functions becomes possible that can also include control of safety-relevant vehicle functions.
