    Abstract: In an axial piston machine with variable displacement with tilted cylinder block, a distributor is coupled with the cylinder block, and a magnetostrictive position sensor has a magnet that is integral with the distributor and a sensor rod that is integral with a fixed body with which the distributor is coupled with the possibility of varying the tilt thereof. The sensor emits a signal that indicates the angular position of the distributor with respect to the fixed body to determine the actual displacement of the machine.

    Abstract: A variable capacity hydraulic machine has a rotating group located within a casing and a control housing secured to the casing to extend across and seal an opening in the casing. The control housing accommodates a control circuit and a pair of sensors to sense change in parameters associated with the rotating group. One of the sensors is positioned adjacent the barrel on the rotating group to sense rotational speed and the other senses displacement of the swashplate. The control housing accommodates a control valve and accumulator to supply fluid to the control valve.

The discharge volume control device (6) can be actuated by an electronic control device (7) functionally connected with a sensor device (9) for measuring the load pressure of the consumer and with a sensor device (8) for measuring the delivery pressure available in the delivery line (4). A circulation device (15) is associated with the delivery line (4) to control the connection of the delivery line (4) with a reservoir (3).

For resetting the swash plate in the direction of a resting position, an elastic element is provided on the actuating piston and on the mating piston, which is supported on a spring bearing arranged on the first side facing the swash plate of the actuating piston or of the mating piston. In the other direction, the elastic element is supported on a second spring bearing arranged on the end facing away from the swash plate of the actuating piston or of the mating piston. When the swash plate is deflected from the resting position, the second spring bearing of the actuating piston or of the mating piston is supported on a counter bearing on the housing side. The second spring bearing of the respective other actuating bearing or mating bearing is supported on a counter bearing on the piston side.
