Pneumatic brake head for shunting and train movement, has axle, whose define deflection is carried out in two stages representing reversible switch and reversible end position with complete opening of compressed air outlet, respectively

摘要

The head (1) has a metal housing with a half-coupling (5) together with a retaining clip, and an axle (3) projecting inwardly to a cylinder from a circular opening. 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.
