Ventilbetätigungseinrichtung

摘要

A valve operating structure for a working vehicle having different control valves with slide spools extending parallel to each other. A control lever is operatively connected to an interlocking member for selectively operating the control valves. The valve operating structure comprises an interlock switching mechanism for moving the interlocking member between a position to engage one slide spool and a position to engage another slide spool. The interlocking member is pivotable about a point located at substantially the same distance to the two spools, with a free end thereof extending to a position between the spools. The two interlocking positions are selectively provided by connecting the free end to one of the spools.
