The working process of the ring cylinder two-group piston two-shaft input rotary pressure pump is as follows:
two sets of pistons are defined as: piston group A and piston group B
The method comprises the steps that when a limiting boss of a piston group A is locked by an anti-thrust supporting tooth of a brake; the piston group B is driven by the power of the input shaft to rotate; the volume of the suction area pump is increased, and negative pressure suction is performed; the volume of the pump in the compression area is reduced, and the compressed air is discharged;
