Abstract
A novel energy storage supercharger comprises an energy storage cylinder which is a sealed cylinder body. Piston parts are positioned in the energy storage cylinder, and a sealing ring is further positioned in the energy storage cylinder to divide an inner cavity of the energy storage cylinder into an air chamber and a hydraulic storage chamber. The novel energy storage supercharger is characterized in that the diameter of the cross section of the air chamber is larger than that of the cross section of the hydraulic storage chamber, and the diameter of a piston face of the piston part in the air chamber is larger than that of a piston face of the piston part in the hydraulic storage chamber. By means of the structural design, the pressure in the air chamber is smaller than the pressure in an air chamber of an existing structure in the background art in the same hydraulic condition in the hydraulic storage chamber. Thus, requirements for the structural strength of the piston sealing ring and an air storage tank are reduced, and danger of the air chamber is reduced when accidents happen. In addition, the required hydraulic value can be flexibly adjusted by adjusting the ratio between the diameters of the two piston faces on the premise without increasing air storage space. Furthermore, the novel energy storage supercharger is low in cost, high in safety, good in adaptability and practical in advancement.
