Abstract

PURPOSE:To prevent leakage so as to reduce operational power by placing a column- or cylinder-shaped valve unit and valve chamber in a cylindrical pair or turning pair with a slight clearance opened, and also sliding the valve unit through an electrically-operated unit while keeping this paired condition. CONSTITUTION:A valve unit 2 is formed in column or cylinder shape and housed as a cylinder or turning pair in a valve chamber 30 of a valve case 3, and a clearance of pair parts is slightly set to a degree of no outflow of gas. A gas inlet 31 is opened to a gas outlet 32 through a gas passage 21 of the valve unit by relatively moving the valve unit and the valve chamber with their pair relation left as maintained, by an electrically-operated driving gear 1. The electrically-operated driving gear 1 comprises a bobbin 12, on which a coil 11 is wound, and a plunger 13, and the driving gear 1 is positioned in a side always placed in a pair condition with the valve chamber 30 to form the pair part in the space to a degree of no leakage of gas, so that leakage is impeded by the valve unit itself with no separate air-tight means required.

[Prior art and its problems] Most of the conventional electric valves used in gas circuits are solenoid valves, and the valve structure is a lift valve type, which always biases the lift valve in the closing direction. The valve is opened by electromagnetic force against the biasing force. In this conventional lift valve, the valve stem of the lift valve passes through a valve case that accommodates the valve body. Therefore, it is necessary to insert an air-tight means such as an O-ring into the valve shaft penetrating portion, and if this air-tight means is damaged, external leakage will occur. Furthermore, since this type of airtight means has a large sliding resistance, the thrust force required to open and close the lift valve becomes large, resulting in an increase in the size of the electric device.
