Abstract:
A direct-action-type electrically-operated valve comprises a valve base ( 30 ) provided with a valve cavity, a motor ( 10 ) disposed on the upper end the valve base, and a screw rod ( 312 ). The screw rod ( 312 ) is fitted and connected to a nut ( 41 ) by means of threads. The nut is connected to a spool ( 42 ). Axial positions of a rotor ( 12 ) of the motor and the valve base are relatively fixed. The upper end of the screw rod is fixedly connected to the rotor. Driven by the nut, the spool moves along the axial direction of the valve cavity to open or close a valve opening ( 30 a ) disposed on the valve base. The spool is a tubular structure provided with a balancing channel, and a seal piece for dividing the valve cavity into two independent cavities is disposed on the periphery of the spool. A gear system is removed from the electrically-operated valve, so that unnecessary rotations are reduced, friction loss is reduced, and a response is direct, reliable and sensitive; the axial positions of the rotor and the valve base are relatively fixed, that is, the relative fixation of the rotor and a coil element during the working enables driving force to be stable; and obviously, for valve openings with a same size, the size of the motor using the valve opening is smaller than that in the background technology, which can meet requirements of miniaturization and large capacity.

Claim (Index 17):
The direct-acting electric valve according to  claim 16 , wherein a housing is sleeved on the upper valve seat, and a coil component of the motor is sleeved on the housing, and is supported by a fixing rest sleeved on the housing, and axial central lines of the coil component, the bearing and the rotor are coincident.
