Abstract
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.
