摘要： A flow control device wherein a valve member is reciprocated linearly by the rotation of a rotor of a stepping motor to change the flow rate of air flowing through an air passage in a housing. To the rotor of the stepping motor is fixed a shaft having external threads. A guide member with a valve member fixed thereto has internal threads for threaded engagement with the external threads of the shaft and also has a stepped, axial bore for fixing the valve member. The valve member is fixed at a sleeve portion thereof to the stepped, axial bore of the guide member. An annular sliding bearing and a wave washer are inserted between the stepped portion of the axial bore of the guide member and an end face of the sleeve portion of the valve member. A small gap is formed between the inner wall of the axial bore of the guide member and the outer peripheral surface of the sliding bearing and also between the outer peripheral surface of the shaft and the inner peripheral surface of the sliding bearing, thereby permitting the sliding bearing to move radially and axially with respect to the shaft.

摘要： A step motor of the linear type is composed of a shaft threadedly engaged with an inner hole provided in a rotor and is driven in the axial direction by rotation of the rotor. A bearing for slidably supporting the shaft for axial movement is installed in a rear cover for covering the rear end of the shaft and an enclosing member for the rear end of the shaft is formed in the rear cover. A spring shoe and a coil spring are fitted to the rear end of the shaft enclosed in the enclosing member. Consequently, the assembly of the coil spring and the spring shoe becomes simple, and the coil spring is not exposed. The form of the front portion of the step motor is made more compact in comparison to that of the prior art where the coil spring is externally installed to the front end of the shaft.

摘要： A step motor of the linear type has a shaft threadedly engaged with an inner hole of a rotor and is slidably supported for axial movement by a front bearing and a rear bearing. A stopper pin that abuts on a stationary portion at the rear end of travel projects from an outer circumferential portion of the shaft. The shaft is moved in the axial direction by the rotation of the rotor and the front shaft bearing is provided with a slot allowing the stopper pin to pass through. Consequently, when the shaft is advanced, the stopper pin for stopping the rear end of travel does not abut on the front bearing, and the advance of the shaft is not limited. The slot, therefore, allows the stroke of the shaft to be lengthened without lengthening the front portion of the housing.
