ABSTRACT:
A regulator comprises a body including an inflow line, an outflow line, and a buffer space, the buffer space being provided between the inflow line and the outflow line, and a switch for opening and closing a flow path of a fluid flowing from the inflow line to the buffer space. The switch comprises a seat member including an inlet for receiving the fluid from the inflow line, and an outlet for supplying the fluid received through the inlet to the buffer space, the seat member being disposed in the flow path and a movable cutoff member for opening and closing the inlet, the cutoff member being inserted into the seat member, wherein the outlet is configured for allowing the fluid to flow in one direction along an outer sidewall of the seat member.
