Claims

[Scope of utility model registration request]

A first fluid chamber, a second fluid chamber that communicates with the first fluid oven, and a third fluid chamber that communicates with the second fluid chamber and has a larger diameter than the second fluid chamber are aligned in a straight line. a cylinder block which is sequentially formed in a shape, a spool that is slidably fitted into the first fluid chamber and partitions the first body chamber and the second fluid chamber; a fluid replenishment passage that is bored and constantly communicates the first fluid chamber and the second fluid chamber; and a piston that is slidably fitted into the third fluid chamber; a piston rod that is slidably fitted into the second fluid chamber and partitions the second fluid chamber and the third fluid chamber; and a piston rod that is bored in the piston rod and has a distal end surface and an outer circumferential surface of the piston rod. an opening/closing passage that opens to the first fluid chamber and is closed by the spool when the piston rond is displaced toward the first fluid chamber; a control port that opens at an end of the second fluid chamber on the first fluid chamber side; and a control port that is provided in the cylinder block and opens at an end of the third fluid chamber on the second fluid chamber side. a supply/discharge port for pressure reduction; a supply/discharge port for pressure reduction that is opened in the end of the third fluid chamber on the opposite side of the supply/discharge port for pressure reduction that is received in the cylinder block, and the third fluid chamber of the piston rond; A pressurized supply/discharge port that communicates with the opening/closing passage by displacement to the side, and a two-position switch interposed between the pressurized supply/discharge port and the reduced pressure supply/discharge port, the pressure fluid supply source, and the liquid storage tank. A fluid pressure control device comprising a valve.
