Fuel-displaced cover plate is provided with, the fuel-displaced cover plate and the pump housing are connected.
When power source turns clockwise, power source band movable gear shaft, pump housing oil suction cavity space is driven by small change by internal rotor
Greatly, parital vacuum is formed, under atmospheric pressure, the check valve closed on is opened, and the check valve of opposite side is closed always, oil
Check valve of the liquid through unlatching enters oil sucting cavity, and internal gear pair continues to engage, and fluid is brought to pumping cavity from oil sucting cavity, pumping cavity
Pressure persistently increases, and reaches the big valve of the inertia pump closed on after certain pressure and opens, and the big valve of the inertia pump of opposite side is closed always,
Fluid is discharged from oil outlet chamber.
During power source rotate counterclockwise, internal rotor changes direction of rotation, and the check valve originally opened is due to the flow direction of fluid
It is opposite to form pressure and close, form parital vacuum at the check valve of opposite side and open.Fluid enters oil sucting cavity, internal gear pair
Continue to engage, original force feed cavity pressure diminishes, and the big valve of the inertia pump at this is closed.The pressure of opposite side oil pocket persistently increases
Greatly, reach the big valve of the inertia pump closed on after certain pressure to open, fluid is discharged from oil outlet chamber.No matter power source be it is clockwise or
Counterclockwise, the gear pump does not change into and out of hydraulic fluid port.
As a kind of optimal technical scheme of the present utility model, oil-recovery tank is provided with the internal rotor and outer rotor, with
Ensure the pressure balance at internal gear pair both ends, avoid because axial force and caused by internal gear pair Fast Wearing phenomenon.
As a kind of optimal technical scheme of the present utility model, the gear shaft is provided at both ends with copper bearing, to ensure
Oil pump remains to keep normal work for a long time under oil-free, the bad working environments of few oil.
As a kind of optimal technical scheme of the present utility model, the both ends of the check valve and the big valve of the inertia are arranged with
O-ring.
As a kind of optimal technical scheme of the present utility model, gear shaft and the internal rotor interference fit.
The beneficial effect that the utility model is reached compared with prior art is：The utility model is compact-sized, rotating speed is high,
Stable drive, noise are low, good reliability；Controlled by the mutual cooperation of 2 check valves and 2 big valves of inertia so that even if dynamic
The rotation direction oil inlet and outlet that changes in power source does not change still.
