ABSTRACT:
A rotary solenoid operated valve assembly having the rotary journalled in a ball race in one end of a tubular pole piece extending through a coil. The tubular pole piece has the end distal the ball race received in the bottom of a cup-shaped stator which has salient poles on the open rim and which define radial air gaps with poles formed on the rotor. A cam formed on the rotor moves a ball valve member in a direction transverse to the rotor axis for controlling flow over a valve seat provided in an inlet or outlet port. The rotor is balanced about its axis of rotation to prevent cam movement when the valve is subjected to vibration in a direction transverse to the rotor axis.
