Abstract

PURPOSE: To heighten the velocity of response and obtain a long lifetime, by composing a valve driver of a step motor and gears, housing the step motor, the gears, etc. in an enclosed container and using a hermetic seal for the power lines of the motor.
CONSTITUTION: A coolant from a coolant inlet pipe 7 passes through the gap between a valve seat 5 and a needle valve 4A and then flows out of an outlet pipe 8. A step motor 1, a gear 3, etc. are housed in an enclosed container 9. Although the coolant enters from the gap between a valve stem 4 and a valve frame 6 into a space defined by the container 9, the coolant does not flow out of the container because it is enclosed. A seal member 10 hermetically seals up connection terminals for leading the power lines 11, 12, 13, 14, 15 of the step motor 1 out of the container 9.
