Background technology
The electric-motor pump that existing market is boarded a plane employs the mode that common electric machine is combined with plunger pump, and the cylinder body of pump is pacified
On rotor, one end of plunger is installed in cylinder body, and the other end of plunger is withstood on swash plate by piston shoes, and can
Slided on swash plate.The check valve and pintle of flow are installed, pintle one end is provided with circumferential hole, can be with the external world on cylinder body
Carry out flow communication.In the course of work, rotor drives hydraulic pump cylinder body rotation, and the plunger installed in cylinder interior can be with
Rotation, and axial displacement occurs in rotary course, the change of volume is produced while axial displacement.In flow check valve
Synergistic effect under, fluid by pintle enter plunger cavity volume or extrude cavity volume, complete assignment process.Pintle high-pressure side
Periphery perforate, is in communication with the outside, and realizes pump oil process.Such a electric-motor pump is the combination of common electric machine and plunger pump, speed governing difficulty
Greatly, processing and manufacturing is complicated.The rotor of motor and pump cylinder separate, caused by overall dimensions it is bigger than normal, it is difficult to install.Pintle and pump
Cylinder body rotates at the same time, and rotary inertia is big, and reaction is slow.
The content of the invention
The shortcomings that in order to overcome the above-mentioned prior art, it is an object of the invention to provide a kind of aircraft high speed diclinic dish axle
To plunger type switching magnetic-resistance synchronous motor pump, realize it is integrally-built compact, noise reduce, flow pulsation is low, whole efficiency
Improve.
In order to achieve the above object, this invention takes following technical solution：
A kind of aircraft is pumped with high speed two inclined plate axial piston switching magnetic-resistance synchronous motor, including motor stator 10, motor
