Abstract

The invention relates to a pneumatic actuator (100) for actuating a functional element (102), in particular a functional element (102) of a gearbox (14) of a commercial vehicle (10), comprising: a pneumatic cylinder (104), the pneumatic cylinder (104) comprising: a cylinder body (108) defining a pneumatic chamber (110) having a main axis (A), and a cylinder head (114) closing the pneumatic chamber (110); a pneumatic piston (106) for actuating the functional element, the pneumatic piston (106) comprising: a piston head (116), a piston rod (118) for connecting the piston head (116) to the functional element (102), wherein the piston head (116) is received in the pneumatic chamber (110) slidable along the main axis (A) between a coupling position and a neutral position, wherein the piston head (116) separates the pneumatic chamber (110) into a first pressure chamber (132) and a second pressure chamber (134), and a bypass (150) to fluidically connect the first pressure chamber (132) and the second pressure chamber (134).
