ABSTRACT:
A method of manufacturing a brake cylinder. The brake cylinder is made form an extruded profile by severing a required length of profile and closing an end thereof with a cap (19). The profile consists of a cylinder jacket (11) with connection ribs (13, 14, 15) projecting therefrom a flange member (22) is fastened to the cylinder jacket (11). The bores (26) for the filling ports and the bores (27) for the pressure connections are bored into the connection ribs (13, 14, 15) radially to the cylinder jacket (11). The bores (26, 27) are also provided with female threads (29) so that respective components may be fastened to the ports and/or outlets. Producing the cylinder by extrusion provides a cylinder jacket of a surface quality high enough to make finishing superfluous.
