Abstract:
A brake cylinder for use in a railway vehicle braking system comprising:(a) a cylindrical casing engageable with such railway vehicle braking system;(b) a hollow piston assembly mounted for reciprocal movement within said cylindrical casing;(c) at least one air bag actuator disposed between and engageable with a first surface of said hollow piston assembly and an opposed inner surface of said cylindrical casing upon actuation of said at least one air bag actuator;(d) air communication means in fluid communication with an interior portion of said at least one air bag actuator for supplying air pressure to said at least one air bag actuator during a brake application of such railway vehicle braking system and for evacuating air pressure from said at least one air bag actuator during a brake release of such railway vehicle braking system; and(e) a piston rod assembly connected with a second surface of said hollow piston assembly, said piston rod assembly capable of movement in an outward direction during such brake application to initiate a braking sequence of such railway vehicle braking system.
