Abstract

PURPOSE:To reduce the installation space and manhour in assembly work by installing a differential area type relief poppet into a main poppet which can be slided for a guide cylinder. CONSTITUTION:A supporting member 7 fitted into a hollow part slidingly contacts a guide cylinder 6. A pilot chamber 15 is formed from the annular projection part 2 of a main poppet P and the stepped part 1c of a valve opening 1, and the main poppet P shifts against a return spring 9 according to the pilot pressure. A relief poppet R is inserted in slidable ways into the supporting member 7 fitted into the main poppet P. When the pressure on an inflow port 10 side becomes over set pressure, the action force on the pressure receiving area A3 side overwhelms the action force on the pressure receiving area A4 side and the spring force of the relief spring 19, and the relief poppet R is opened.
