Background
The conventional energy accumulator is of an equal-area type, and the pressure of an air cavity and the pressure of an oil cavity are balanced. Depending on the system pressure, the inflation pressure is typically 0.7 times the system pressure. If the system pressure is high, a very high gas pressure is required to be flushed in. Thus, an inflator with a relatively high pressure is required, and is difficult to realize.
In summary, the present invention provides an accumulator with a boosting function.
