Abstract
PURPOSE:To drive a valve and eliminate foreign substances pinches in valve parts by inserting a hollow cylindrical valve with a venturi part, into a cylindrical valve box, and making pressure in both large and small diametral parts of this venturi part act on spots in front and in the rear of a piston installed in the hollow cylindrical valve. CONSTITUTION:A cylinder chamber 11 is formed in a cylindrical valve boxy 1 with an inflow port 2 and an outflow port 5, and a hollow cylindrical valve 15 with a piston part 16 is inserted into the inner part free of movement in the axial direction. A spring 25 is set up in this cylinder chamber 11, energizing the valve to the inlet side. A venturi part 19 is installed in the valve 15, while pressure at the venturi large diametral side is made to act on the front side of the piston part 16 via a first conducting hole 28, and pressure in the venturi small diametral part 18 is made to act on the rear side of the piston part 16 via a second conducting hole 29. With this constitution, an orifice between the valve 15 and a valve seat 31 is adjusted so as to cause a flow rate to become constant, so that foreign substances are pinched in the orifice and the orifice is open, thereby eliminating the foreign substances.
