Abstract

PURPOSE: To absorb work error from valves by elastic members, by fitting elastic members in the parts where a plurality of valve come in contact with each other, in a proportional control valve to control the amount of air supplied to an engine of car.
CONSTITUTION: When an electrical current flowing to a coil 2 is not enough to open valves, passages for the air acn completely be closed, since a valve 11 is closely contacted to an orifice 9 pushed by a spring 13, while a valve 10 is also closely contacted to the orifice 8 pushed by a coil spring 23. When an electrical current, of which attracting force acting to a plunger 4 surpasses the spring force of coil spring 23, flows to the coil 2, the valve 10 is moved to open the orifice 8 to the valve through which the air is flowed in. Moreover, when the amount of electrical current to flow to the coil 2 is increased, the valve 11 is moved by the spring 13 compressed, along with the coil spring 23 further compressed, threrfore, both valves 10 and 11 are opened.
