Abstract
A motorized bypass valve having a valve body with cylindrical valving chambers with a single inlet and a first and second outlet ported to the chamber, such with convexo-concave face seals disposed over the ports. A rotary valving member having a partial cylindrical valving surface is disposed in the valving chamber and valving surface contacting the face seals. A motor housing is then spin welded onto the valve body to seal the valving chamber with the half shaft of the valving member extending into the motor housing and sealed by an O-ring. The motor and gear train are then assembled into the housing for driving the half shaft. The motor housing is closed by a cover welded thereover.
