A hinge for the rotatable movement of a closing element, such as a door, a window, a shutter or the like, includes a fixed element anchorable to a stationary support structure and a mobile element anchorable to the closing element. The fixed and movable elements are mutually coupled so as to rotate with respect to each other between an open position and a closed position. One of the fixed or movable element includes a working chamber, with a plunger disposed to slide along a longitudinal axis and operatively coupled with the other one of the fixed or movable elements so that the sliding of the plunger corresponds to a rotation of the movable element.

A door operator includes a housing and at least one linearly guided piston in the housing. A roller carrier is disposed in the piston and includes a rotatably movable supported pressure roller. The piston is formed as a deep drawn structural component and includes a bottom and a circumferential walling. The support and the axial guiding of the roller carrier with a pressure roller within the piston can be realized in a simple and cost effective manner. Furthermore, an aperture is provided in the bottom of the piston, through which the pressure roller protrudes to the outside beyond the bottom of the piston.

A door actuator for opening and/or closing a door leaf includes a housing, an output shaft rotatably supported in the housing and with a cam disc, wherein the output shaft is formed for transferring torque onto the door leaf. A first element of motion is linearly movably guided in the housing with a first contact surface. A second element of motion is linearly movably guided in the housing with a second contact surface. A distancing arrangement is disposed in the housing. The cam disc is disposed between the two contact surfaces and for rolling on the two contact surfaces. In at least one delimiting range of angles of rotation of the output shaft, the distancing arrangement delimits the minimum distance between the elements of motion, and, in at least one free range of angles of rotation, does not delimit the linear mobility of the two elements of motion in relation to each other.

A hinge device includes a fixed element, a movable element and a slider housed in a working chamber and coupled to a pivot, so that a rotation of the movable element corresponds to the sliding of the slider. The working chamber includes an end cap and a working fluid and is divided into first and second variable volume compartment by a plunger member of the slider. A hydraulic circuit includes a first duct passing through an end cap that is in fluid communication with the first and second compartments and has an elongated tubular wall extending within the working chamber, and the interspace between the working chamber and the elongated tubular wall. The plunger member is tightly inserted in the elongated tubular wall, which includes a first peripheral conduit having a first and a second port in fluid communication with the first and respectively second first compartment through the first duct.

The present disclosure relates to a motor vehicle, comprising a leaf element, which is movably held at a bearing point of the motor vehicle, and an adjusting device by means of which the leaf element can be moved between a closed position, in which the leaf element closes an opening of the motor vehicle, and an open position, wherein the adjusting device comprises a spring component which, on the one hand, is coupled at least indirectly to the leaf element and, on the other hand, at least indirectly to a holding region of the motor vehicle, and which comprises a sleeve element and a piston element which is inserted into a sleeve interior of the sleeve element in certain regions and is displaceable relative to the sleeve element during the movement of the leaf element between the closed position and the open position. The spring component is designed as a spring strut and comprises a damping device for damping during the displacement of the piston element relative to the sleeve element during the movement of the leaf element between the open position and the closed position. A further aspect of the present disclosure relates to an adjusting device.

One embodiment relates to a door operator including an operator body including a rotatable pinion, an arm connected to the pinion, an inductive sensor mounted adjacent the arm, and a controller in communication with the inductive sensor. The inductive sensor includes an inductor comprising a plurality of nested coils, and each of the coils is curved about the pinion. The controller is configured to provide the inductive sensor with a varying power signal, and the inductive sensor is configured to inductively link the inductor to the arm in response to the varying power signal. The inductive sensor has a characteristic which varies in response to the rotational position of the arm when the inductor is inductively linked with the arm. The controller is further configured receive information relating to the characteristic, and to determine the rotational position of the arm based upon the received information.
