Abstract: A hydraulic pilot valve unit constructed with an aim of controlling the flow rate of fluid under pressure in proportion to the stroke of the operating lever, irrespective of the speed of operation of the lever, and adapted for use in supply of pilot fluid under pressure by a pilot fluid actuated type changeover valve or the like arranged to be actuated for switch-over by pilot fluid under pressure. This hydraulic pilot valve unit includes valve spools 23 each being slidably movable between a first position where the pilot fluid under pressure supplied by a pilot pressurized fluid supply pump (27) is allowed to flow into outlet ports (26) formed in the valve body (1), and a second position where the outlet ports are allowed to communicate with a reservoir port (30) formed for drainage purposes.
