Abstract
A railway brake cylinder includes a body (11′); a piston (13′) mobile relative to the body (11′) to act on a brake linkage and delimiting with the body (11′) a pressure chamber (10′) adapted to be supplied by a pneumatic pressure agent source; an auxiliary actuating member (26′) mobile relative to the body (11′) and the piston (13′), mechanically connected to manual operating elements to cause it to occupy either a rest position in which it is away from the piston (13′) or a pushing position in which it is in contact with the piston (13′); two orifices (73′, 51′) in fluid communication with the chamber (10′) and the atmosphere, respectively; and selective connecting elements (28′) between the two orifices (73′, 51′), the elements (28′) being mechanically connected to the auxiliary actuating member.
