<p>A hydraulic pilot valve consisting of a pair of pressure-reducing valves, wherein a stopper which can freely adjust maximum control inputs of operating levers of the hydraulic pilot valve is provided to make maximum pilot pressures output from the pair of pressure-reducing valves freely adjustable. Furthermore, in the hydraulic pilot valve, a stopper member for regulating a maximum control input of an operating lever is fixed to an operating lever, so that an operating force during a maximum operation of an operating lever is received by a member fixed to the operating lever. Furthermore, in the hydraulic pilot valve, an erroneous operation due to vibrations and the like are prevented by a damper mechanism interposed between a lever and a main body of the valve and fixed to an operating lever. Furthermore, a shuttle valve interposed between the output ports of the pressure-reducing valves can simplify the construction of the hydraulic pilot valve for taking out a maximum pilot pressure out of the pilot pressures of the output ports. <IMAGE></p> |
