Valve 6 is opened, and compression fluid is flowed out from drain tap 6；When permanent magnet piston 2 reaches the position P ', drain tap 6 is closed, air inlet
Valve 5 simultaneously closes off, and gate 4 is opened, and when permanent magnet piston 2 returns to position P by gate 4, gate 4 is closed, and completion once follows
Ring.
The low-pressure fluid for flowing into circular ring shape pipeline 1 from air intake valve 5 is compressed into high-pressure fluid and is discharged from drain tap 6,
Play the role of compressor.Fluid can be gas, be also possible to gas-liquid mixed two-phase fluid, it is not possible to be incompressible flow
Body.
2 one-way movement of permanent magnet piston, energy loss are smaller in the process of running for permanent magnet compressor in the present embodiment, than past
Dual Piston it is high-efficient.Meanwhile structure is simple, dynamic component is few, is suitble to miniaturization and micromation.
Permanent magnet piston 2 in the present embodiment is permanent magnet mover, the mover of excitation can also be substituted for, as long as energy
Achieve the effect that make mover forward slip compression fluid.
The foregoing is merely preferred embodiment of the present application, are not intended to limit this application, for the skill of this field
For art personnel, various changes and changes are possible in this application.Within the spirit and principles of this application, made any to repair
Change, equivalent replacement, improvement etc., should be included within the scope of protection of this application.
