求の範囲第１項記載のバルブ装置。[Claims for Utility Model Registration] (1) An annular groove in which one end of a port of a valve seat member opens is partitioned by an outer circumferential seat portion and an inner circumferential fixing portion formed on one end surface of the valve seat member. A perforated non-return valve disposed so as to close the annular groove has its outer peripheral end adjoining the outer peripheral seat part so as to be able to be seated and moved freely, and its inner peripheral end is placed under the bias of a non-return spring. and a leaf valve arranged so as to be floating in the non-return valve and arranged adjacent to the non-return valve has its outer peripheral end facing inside the annular groove, and its inner peripheral end faces the inner peripheral side fixing part and the same. A valve device characterized in that it is held between a fixing member and a fixing member. (2) The valve device according to claim 1, wherein the valve seat member is a piston body of a piston part in a cylinder or a valve case of a base valve part in a cylinder. (3) The valve device according to claim 1, wherein the leaf valve is multi-layered and valve bodies having different outer diameters are stacked.
