Electro-pneumatic air pressure regulator |
摘要 |
An electro-pneumatic air pressure regulator includes a primary pressure introduction port (12), a secondary pressure output port (13), a pilot pressure chamber (30), a main valve (15) for opening and closing a communicating conduit (14), a floating piston (20) which actuates the main valve, a nozzle conduit (46) via which the pilot pressure chamber (30) is communicatively connected to the atmosphere, a flapper (40) which includes a leaf spring (40a) facing an open end of the nozzle conduit, and an electromagnetic drive system (42) which deforms the leaf spring to vary a position of the flapper relative to the open end of the nozzle conduit in accordance with the magnitude of an analogue input signal. The flapper includes a conical projection which projects toward the open end of the nozzle conduit. A conical recess corresponding to the conical projection is formed on an end face of the nozzle conduit around the open end thereof. <IMAGE> |
