Abstract

PURPOSE:To compact a relief valve by providing a pressure reducing function, a rotary driving force function and a fluid transfer function to the inside of a machine without injecting energy from the outside by using the relief valve having energy restoring mechanism which utilizes kinetic energy of flowing fluid. CONSTITUTION:A liquid flowing into the actuating valve 1 of a relief valve is allowed to pass through a convergent high speed tube 2 at the exit of the actuating valve 1 and is injected from an injection opening 3 into an outer tube 4 provided on the outer periphery. At the upper portion of the outer tube 4 an actuating tube 6 is continued to an intake chamber 5 provided outside the high speed tube 2 and an opening 7 is located inside the intake chamber 5. The intake chamber 5 is converted to a pressure reduced state by the flow speed of the liquid injected from the injection opening 3, and, when the actuating tube 6 is connected to a pressure switch, the pressure switch is actuated. Also, when the actuating tube 6 is connected to a specific liquid and/or gas, the liquid and gas can be absorbed and discharged from the outer tube 4 and so the quantity of the liquid and gas can be adjusted; or, when the actuating tube 6 is connected to a mechanism which particularly needs pressure reduction, pressure within the pressure reducing mechanism can also be adjusted.
