  A cross-sectional view of a prior art pump is shown in FIG. The pump shown in FIG. 9 manually operates the lever 41 to suck in oil. By moving the lever 41 up and down, the air in the oil storage cylinder 42 is sucked, and the air flows to the piston pipe 47 through the vertical duct channel 43, the horizontal duct channel 44, the space 45, and the central hole 46. The air in the oil storage cylinder 42 is gradually discharged by being discharged to the outside by the one-way pressure release valve 48 at the bottom end of the piston pipe 47, and the external oil is stored in the oil through the oil suction pipe 49. Inhaled into the cylindrical body 42.

However, although the above-mentioned conventional pump has a basic oil suction function, it does not have an oil discharge function. Therefore, when it is desired to drain the oil in the pump, it is very inconvenient to remove the oil from the oil storage cylinder by removing the top cover. Furthermore, when the user has two requirements of oil suction and oil discharge, an extra pump having an oil discharge function must be purchased. In this way, not only the extra purchase cost is required, but also the use of the pump is inconvenient because the pump cannot be used for both oil suction and oil discharge functions. In addition, if two pumps are purchased, the space occupied by the two pumps will be larger than that for a single pump, so there will be insufficient space for installation and a problem of the pump installation location will occur.
A main object of the present invention is to provide a pump having a function of discharging and sucking oil in order to solve the above-described problems.
