Pneumatic device for braking system - has thin shell with orifice in which valve member may be preset using projection received in recess

摘要

The device (1) comprises a thin shell (3) with an orifice (6) which carries a valve (2). The circumference of the orifice (6) and the outside surface of the valve body have projection (8) and corresponding recess (9) to hold the valve in the preset angular position. The cock has a threaded part running in a threaded part of the ferrule or other tubular member. This is facilitated by a circular shoulder (10) providing a face for the orifice surround to seal against.
