METHODS AND SYSTEM FOR PASSING SIGNALS THROUGH A PIPE BRACKET

摘要

A manuel vent (40) and an emergency brake valve (42) are coupled to a pipe bracket (10) such that the manual vent is in flow communication with the emergency brake valve utilizing a passageway between a service side (12) of the pipe bracket and a emergency side (14) of the pipe bracket. When the manual vent is actuated, the passageway is pressurized which resets the emergency brake valve. Once the emergency brake valve is reset, the passageway is opened to atmosphere. Accordingly, a signal is passed through a pipe bracket.
