This type of pump relies on internal control (or external control) to manipulate the variable mechanism through oil pressure. The variable characteristics of the oil pump are shown in Figure 4-1. From the graph, it can be seen that the pressure regulation range of the pump is relatively small. After the oil pump generates a variable at 3-4 MPa, the flow rate quickly decreases to the required high-pressure flow value. This type of pump is actually equivalent to a high and low pressure combination pump, and the driving power of the pump can be calculated by referring to the power selection method of the pressure compensated variable pump.
