1. Principle
If DC current through the loop coil, the balance between the torque is produced by armature of the bevel side (outer side) and torsional spring force,and then drive the rotor rotation,adjust fuel output with the engine speed changes.
2. PT Actuator is built-in type presice device,which there is a split gap and produces relative motion, inner with plunger or cardan joint.
3. Type:
Normally closed and normally open type
According to generator power, there are small flow 200-300KW, medium flow 400-600KW, large flow 800 KW. the flow depends on fuel hole diameter.
