MOTORIZED FLOW RATE CONTROL VALVE

摘要

On one end of a rotor and a face opposite to that end, there are provided holding sections having a function to center a ball to be held between them and thereby to dispense with a sleeve bearing, and a boss, protruding from a motor housing toward a motor holder, to position and hold a bearing, is provided integrally with the motor housing, thereby enhancing accuracy of rotor-stator alignment, a simplifying bearing structure for the motor and improving shaft aligning accuracy.
