A hydraulic-pressure storage reservoir based on a pressure-storing liquid, and a hydraulic system, that utilize the high pressure and compressibility of the pressure-storing liquid to store hydraulic pressure by means of the hydraulic-pressure reservoir. The hydraulic-pressure reservoir comprises a tank chamber formed by a tank shell enclosure. The tank chamber is divided into two sub-chambers by a movable spacer (HS). One sub-chamber is filled with a pressure liquid, and is therefore called the pressure-liquid chamber (YYQa). The pressure-liquid chamber is provided with a liquid inlet (ZYK) and a liquid outlet (PYK) connected to the outside; the other sub-chamber is filled with a pressure-storing liquid, and is therefore called the pressure-storing-liquid chamber. The pressure of the pressure-storing liquid is controlled to a constant standard pressure, and the pressure storage chamber is therefore at same constant standard pressure. By means of pressure transmission through the spacer (HS), the pressure of the pressure-liquid chamber is equal to the pressure of the pressure storage chamber. The hydraulic-pressure storage reservoir and hydraulic system can be applied to hydraulic power assisting system. As the pressure is stored in liquid, a pump of only small power is needed to maintain enough liquid pressure within the hydraulic-pressure reservoir, and the hydraulic-pressure drive can react in a timely manner.
