How to adjust the flow of piston pump?
The oil pan with oil liquid through the suction port and the piston cylinder; from 180 degrees to 360 degrees, the piston cylinder volume decreases, so the oil liquid in the pan with oil discharged from the outlet of the liquid. The pump works continuously as long as the drive shaft rotates.
Changing the size of the current in the solenoid valve can change the angle of the tilting element, and then change the stroke length of the plunger in the pump cylinder, that is to say, to change the flow of the pump. An inclined angle is called a quantitative pump, and the angle of inclination can be changed, which is called a variable pump.
For the swashplate valve controlled by the solenoid valve, the swashplate is in an angle with the cylinder body, so the plunger is reciprocating in the pump cylinder when the cylinder rotates. It goes from 0 degrees to 180 degrees, that is, to the upper plunger position, the plunger cylinder volume gradually increased
