Abstract

PURPOSE:To prevent a pressure breakdown from occurring to a downstream pressure equipment, by equipping a fluid regulator with valves which reciprocate together with the 1st and the 2nd pistons to open and close passages extending to the working fluid chambers of the pistons, pressure governor springs for energizing the pistons, etc. CONSTITUTION:The piston 3 and valve 5, and piston 4 and valve 6 are pressed down by the pressure governor springs to send high-pressure fluid to a downstream side 19 through an entrance 7, filter 8, entrance chamber 9, passages 10 and 11, working fluid chamber 12, passage 13, entrance chamber 14, passages 15 and 16, working fluid chamber 17, and passage 18 when the passages 10, 16 communicate with the entrance chambers 9 and 14 through the passages 10 and 15, but when the sum of operating pressure on the piston 3, the spring force of an auxiliary spring 22, and supply fluid pressure operating on the valve 5 increases above the force of the governor spring, the piston 3 is elevated against the pressure governor spring to move the valve 5 up to the position where the passage 11 is closed by the auxiliary spring 22, stopping the supply of pressurized fluid to the downstream side 19.
