摘要： A proportional type electromagnetic valve comprises a flow rate control valve secured to a movable core which moves a stroke in proportion to the input current, and a valve seat portion cooperative with the flow rate control valve to control the flow rate. In addition to a bias spring providing for urging the flow rate control valve toward the valve seat portion, a second spring is disposed on the movable core for urging the flow rate control valve to release it from the valve seat portion. The resultant force of the two springs makes the stroke of the flow rate control valve proportional to the input current.

摘要： An exhaust gas recirculation control system for controlling the amount of exhaust gas subjected to recirculation to the air inlet depending on the amount of inlet air of an internal combustion engine. This system comprises a control valve disposed in an exhaust gas recirculation passage, for controlling the amount of exhaust gas recirculation, an orifice disposed in the recirculation passage, for creating a negative pressure upstream of the control valve, and a solenoid valve for generating a pressure which controls the control valve. The solenoid valve comprises a core formed therein with a hollow passage opened at one end to a valve portion, a plunger made of a magnetic material and having a valve seat opposing the open end to define the valve portion, a spring biasing the plunger in the opening direction of the valve portion, a first exciting coil generating, when passing therethrough a current proportional to the amount of inlet air, a force acting on the plunger to close the valve portion, and a second exciting coil generating, when passing therethrough a current in inverse proportion to the pressure downstream of the orifice, a force opposite to the force on the plunger due to the first exciting coil.
