Abstract

1. A pneumatic indicating device for the state of application of rail vehicle friction brakes, which is loaded with the pressure in the brake cylinder (pipe 5) as a function of the pneumatic or mechanical actuation of the friction brake, which possesses at least one brake cylinder (7) to which compressed air is applied, the said pneumatic indicating device having not less than two visual displays (9, 9') which can be adjusted by means of compressed air against the force of the spring, each of these displays possessing an indicator (10, 10', 17, 17') which can be moved to a visual opening, the pressure in the brake cylinder being applied to at least one of the aforementioned indicators, and further possessing the characteristic feature that the compressed air port (15) of the second visual display (16, 16') is connected to the output port (13) of a twin check valve (12), one input port (11) of which is pneumatically connected to the brake cylinder (7) and the other input port (23) of which is pneumatically connected to a gate valve (21) with venting, the said twin check valve (12) opening a passage from one of its input ports (11 or 23) to the output port (13) while blocking off the second input port (23 or 11), whereby the gate valve (21), which is connected to a constant compressed air source (20), can be switched by means of a rod (nut 25) for the mechanical actuation of the friction brake and is only opened in its operating position.
