The utility model discloses a voltage regulator device relates to voltage regulator device technical field, including outside cylinder, it is first to be equipped with the piston in the outside cylinder, and the first inner chamber with outside cylinder of piston is cut apart to become outer the confession and is pressed chamber and outer storing box chamber, and outer storing box intracavity is equipped with inner cylinder body, and inner cylinder body inner piston head two, supply to press chamber and interior storing box chamber in piston head no. 2 is cut apart inner cylinder body's innerchamber become, and interior storing box chamber is equipped with out the fat mouth, goes out on lateral wall that the fat mouth passed outside cylinder is connected to outside outside cylinder 1's confession fat pipeline, installs fat check valve and at least one play fat check valve on inner cylinder body's the lateral wall. The utility model also discloses a centralized lubrication system of having voltage regulator device. The utility model provides an in relevancy through the pressure balance relation between voltage regulator device's inner cylinder body and the outside cylinder, a plurality of fat check valves can adapt to the pressure oscillation of within range by a relatively large margin, and can be quick adjust the pressure oscillation improves voltage regulator device's response speed.
