The definition of positive and negative flow control: The so-called positive and negative flow control refers to the control method of the pump. The variable pump has a control port. If the control pressure of this control port is higher, the pump displacement is larger, which is the positive flow control. The opposite is negative flow control. Positive and negative flow control means that the variable pump obtains the required flow through pressure control: negative flow control means that the pressure of the hydraulic control increases;
