Abstract

PURPOSE:To effect negative pressure control in a high accuracy by a constitution wherein the vacuum is controlled in accordance with an equilibrium relation between a resilient force given to a spring diaphragm of which resilient force is changed by an electromagnetic device and a force given to the diaphragm by the vacuum. CONSTITUTION:When the vacuum in a diaphragm chamber 6 is small, a valve element 17 is seated to a valve seat 19 to shut off the communication betweeen the diaphragm chamber 6 and an atmosphere releasing chamber 7 and is separated from the tip end of a tubular member 10 to open a vacuum introducing port 11 into the diaphragm chamber 6. On the other hand, when the force given to a diaphragm 5 by a pressure difference is larger than the resilient force of the compression coil spring 30, or when the vacuum in the diaphragm chamber 6 is large, the diaphragm 5 is displaced upward deflecting the compression coil spring 30, the valve element 17 is abutted against the tip end of the tubular member 10 to close the vaccum introducing port 11 and also is separated from the valve seat 19 to bleed the vacuum.
