US 2017/0284552 A1 · RELIEF VALVE

Abstract

Provide is a relief valve in which the flexibility of an attaching position is higher than a conventional relief valve. In the relief valve of the present invention, a discharge hole for discharging a fluid is arranged on a side surface of a cylindrical portion which protrudes from an end surface of a head portion in a bolt-type valve body. A direction change member which changes a direction in which the discharge hole is open to an arbitrary direction is provided. In this way, the relief valve is attached to a fluid device, and then with the direction change member, it is possible to direct the fluid discharge direction to a desired direction, and accordingly, the flexibility of the attaching position of the relief valve is enhanced as compared with the conventional relief valve.
