Latest Patents

Hiroyuki Ishigure holds a patent for an oil leak prevention structure of a vacuum pump. This invention involves a vacuum pump that draws gas by operating a gas conveying body in a pump chamber through the rotation of a rotary shaft. The design includes an oil housing member that defines an oil zone adjacent to the pump chamber. A stopper, located on the rotary shaft, rotates integrally with it and prevents oil from entering the pump chamber. The circumferential wall surface surrounding the stopper is inclined, ensuring that the distance between the wall surface and the axis of the rotary shaft decreases toward the oil zone. This innovative design effectively minimizes the risk of oil leaks during operation.
