VALVE FOR REDUCING THE MANUFACTURING COST OF A VALVE BY OPENING AND CLOSING THE VALVE WITHOUT USING HIGH-PRICED PARTS AS A STEPPING MOTOR

摘要

PURPOSE: A valve is provided to open an outlet suitable for a purpose by a resistance value by using a sensing unit which is comprised of resistors which have different resistance values.;CONSTITUTION: A valve(1) comprises a housing(10), a connector, a motor, and a sensing unit. The housing comprises an inlet(i) in which a fluid flows in and a plurality of outlets(O1,O2,O3) in which the fluid is exhausted. The connector selectively connects the inlet and one or more outlets. The motor creates rotatory power rotating the connector. The sensing unit is composed of resistors having different resistance values. The sensing unit senses the outlet connected with the inlet with the resistance values. The number of resistors is the same as that of the number of outlets.;COPYRIGHT KIPO 2010
