Abstract
An electromagnetic control valve is provided with a housing having an inlet and two outlets extending through the wall of the housing. A valve member is mounted in spaced relation from each outlet opening on a resilient member for movement into and out of engagement with a valve seat surrounding the outlet opening. An elongated valve actuator is pivoted at its mid-point between the two valve members and is provided with a projection adjacent each end disposed in contact with a respective valve member. A spring normally biases the valve actuator about its pivot point to bias one of the valve members into engagement with its associated valve seat. An electromagnet is located on the opposite side of the valve actuator from said one of said valve members to pivot the valve actuator against the force of the spring.
