Claims

[Claims for Utility Model Registration] 1. A valve body for adjusting the opening degree of the gas flow passage is provided in the gas flow passage, and the valve body is connected to the primary side pressure chamber communicating with the inflow side of the gas flow passage and the outflow side. The valve body corresponds to an orifice connected to a diaphragm stretched between a secondary pressure chamber communicating with the primary pressure chamber, and formed in a discharge passage for discharging gas in the primary pressure chamber to the outflow side of the flow passage. A throttle valve is provided, and the pressure in the primary side pressure chamber is adjusted by changing the degree of restriction by moving the valve body of the throttle valve with respect to the orifice, thereby controlling the set pressure on the outflow side of the flow path. In the pressure control valve, the valve body of the throttle valve is fixed to two free leaf springs, which are arranged substantially parallel to each other with an interval in a direction substantially perpendicular to the operating direction of the valve body, and have one end fixed to the case. A solenoid that engages the movable core fixed at the end and attracts the movable core in a diagonal direction with respect to the length direction of the leaf spring by excitation is installed on the side of the movable core substantially opposite to the two leaf springs. A pressure control valve characterized by being provided with a pressure control valve. 2. A utility model according to claim 1, wherein the shape of the two leaf springs in a free state is bent so that they are substantially straight in the center of the moving stroke of the movable iron core. Pressure control valve.
