An empty/load valve with a housing from which a reciprocable rod which actuates a changeover spool extends, and a pivotable load measuring arm mounted in offset relation to the axis of the rod and carried by a pivotable shaft. The shaft is mounted on and extends from a rigid cover secured to the housing, and the shaft is interconnected with the rod by a linkage. Most of the shaft, the rod and the linkage are covered by the cover in a dust free manner so as to protect them from dust, etc., of the ambient. Preferably, stops extend from the housing to limit the movement of the arm.

Protective cover for emply/load valve actuator

Empty/load braking apparatus for individually controlling the braking of the trucks of railway cars and an empty/load valve unit for such use and adapted to be mounted on each truck. The valve unit has a body with a canister as a part thereof or secured thereto with a changeover spool in the body and operable by a load sensing arm, with an air passageway extending between an inlet for receiving pressurized air from the conventional air line and an outlet for connection to a brake cylinder, with a proportional spool for controlling the air passing through the passageway, with a release spool for quick release of air from the brake cylinder upon brake release and with a check valve for preventing the entrance of air into the canister from the braking apparatus during brake release.
