DOOR ACTUATOR
The present disclosure relates to a door actuator (10), particularly a hydraulic door closer, for a door leaf. The door actuator (10) comprises a housing (12) for mounting to the door leaf, a shaft (14) rotatably supported in the housing (12) for actuating the door leaf. The shaft (14) includes an eccentric cam (28). The door actuator (10) comprises a piston assembly (16), particularly a hybrid piston assembly, including an outer piston unit (30) reciprocatingly supported in the housing (12) to follow the eccentric cam (28), and an inner piston unit (32) reciprocatingly supported in the outer piston unit (30) to follow the eccentric cam (28).
