However, in the conventional sputter pump as described above, the fluid filled in the space between the impeller and the inner circumferential surface of the vortex chamber in which the impeller is provided is not pumped, so the vacuum efficiency of the vortex chamber is lowered and the forced suction force of the fluid is lowered as well as the pumping efficiency is lowered. There was this.

The present invention has been proposed to solve the above conventional problems, the object of the present invention is to pump the fluid filled in the space between the impeller and the inner circumferential surface of the vortex chamber to increase the vacuum efficiency to increase the pumping efficiency The present invention provides a sputter pump that can be used.

The sputter pump of the present invention for achieving the object of the present invention as described above is formed in the vortex chamber and the fluid flows in the inlet hole formed in the direction of the rotation axis and the inlet hole formed in a direction perpendicular to the discharge hole is to discharge the fluid The casing formed in the vortex chamber and axially coupled to the rotational shaft to form the inside of the vortex chamber in a vacuum state so as to suck the fluid into the inlet hole and to discharge the ejected hole into the drum shape. A spur pump having a fluid inlet and an outlet formed on an outer circumferential surface, wherein the outlet comprises an impeller configured to have a spiral flow path from the center of the drum on which the inlet is formed to the outer circumferential surface; The impeller has a communication hole communicating with the space between the impeller and the inner circumferential surface of the vortex chamber and the fluid inlet, and guides the fluid filled in the space between the impeller and the inner circumferential surface of the vortex chamber to the fluid inlet and then through the outlet. It is configured to discharge to the discharge hole, characterized in that the side of the impeller facing the space between the impeller and the inner peripheral surface of the vortex chamber is provided with a longitudinal guide groove connected to the communication hole.

The sputter pump of the present invention made as described above transfers the fluid filled in the space between the impeller and the inner circumferential surface of the vortex chamber to the fluid inlet through the communication hole to be discharged to the discharge hole to easily pump the vacuum efficiency of the vortex chamber. It has the effect of increasing the pumping efficiency by increasing.
