Abstract
A fluid brake control system is disclosed for having an improved brake cylinder release control device for use in association with a brake control pipe, a fluid reservoir, and a service valve. The control device has a housing containing a differential abutment subject to actuation from a normal position by differences in pressure between a release spring in a chamber on one side of the abutment and pressure selectively applied to the abutment in another chamber on the opposite side of the abutment. A plurality of poppet type valves operated by longitudinal push rods connected by a bridge are provided in the chamber on each side of the abutment, the bridge being actuated at a midpoint by the abutment.
