Turbo-blower for laser medium gas
First Claim
1. A turbo-blower for use with a laser oscillator to provide a flow of a laser medium gas under pressure, comprising:
- an impeller with a rotation axis, said impeller sucking a laser medium gas in an axial direction and discharging the laser medium gas in a radial outward direction;
a casing including a gas passage for providing a spiral flow of the laser medium gas discharged from said impeller; and
a collecting section provided in said casing and including a chamber fluidly communicated with said gas passage, said collecting section collecting particulates contained in the laser medium gas into said chamber due to centrifugal force generated in the laser medium gas flowing through said gas passage.

Abstract
A turbo-blower for use with a laser oscillator to provide a flow of a laser medium gas under pressure. The turbo-blower includes an impeller with a rotation axis, the impeller sucking a laser medium gas in an axial direction and discharging the laser medium gas in a radial outward direction; a casing including a gas passage for providing a spiral flow of the laser medium gas discharged from the impeller; and a collecting section provided in the casing and including a chamber fluidly communicated with the gas passage, the collecting section collecting particulates contained in the laser medium gas into the chamber due to a centrifugal force generated in the laser medium gas flowing through the gas passage. The chamber of the collecting section is fluidly communicated with the gas passage through a slit locally formed in a wall of the casing.
