The axle exhibits an actuation lever (4) at an external end. A groove disk is arranged at a lower end of the axle and is supported to a valve disk by an axial spring force using a compression spring. The axle is positively engaged to locking disk. A define deflection of the axle is carried out in two stages representing a reversible switch and a reversible end position with complete opening of compressed air outlet, respectively.",
