Abstract (en)
The present invention relates to a position sensor (4) for detecting the position of an actuator piston adjusting, for example, a variable geometric turbo charger or an exhaust gas recirculation valve, comprising a displacement transmission structure, as well as a kit (1,4) for an actuator (1) comprising said position sensor (4), and a method for determining the position of an actuator piston. In order to facilitate the detection of the position of the actuator piston of an pneumatic actuator (1), even if the piston is tilted with respect to the actuator box, the displacement transmission structure comprises a slider (39), to be lineally displaced in the position sensor (4), with at least one marker (40'), of which the translational position can be detected by the sensor (4), a transmission element (38) for interconnecting the actuator piston and the slider (39), a first connection means (41) adapted to connect the slider (39) and the transmission element (38) translationally rigid and pivotable on at least two rotation axes that are perpendicular to each other and a second connection means (42) adapted to connect the transmission element (38) and the actuator piston translationally rigid and pivotable on at least two rotation axes that are perpendicular to each other, and the sensor (4) further comprises a sensor body with a reception (44') adapted for guiding the slider (39), and at least one sensor element (68) adapted to generate an output signal indicating the position of the marker (40') in the reception (44').
