Abstract
A hydraulic system micro-adjustment device and a tank calibration system including same are disclosed. The device includes a base, a piston, valve body, valve core, and handle. The valve body includes an inner cavity for receiving the valve core from an upper portion of the valve body, the valve core being in threaded connection with the inner cavity. The piston is inserted into the inner cavity from a lower portion of the valve body and abuts the valve core. The lower portion of the valve body is mounted in the base and is in communication with oil passages therein. The handle is connected to a top of the valve core, which is movable along the inner cavity upon rotation of the handle thereby pushing the piston along the inner cavity so as to change the volume of a cavity formed by the base, the valve body, and the piston.
