Abstract

PURPOSE: To vary a clearance between the inner surface of a casing and the outer circumferential surface of a rotor, decrease a leakage of air volume and prevent a poor operation of the rotor by a method wherein the rotor is moved in response to a load to be applied to the rotor.
CONSTITUTION: Rotor 18 is formed with a tapered portion 20 at its outer circumferential surface corresponding to the tapered portion 16 of the casing 10. Rotary shaft 24 is composed such that the same may be moved axially along with the rotor 18 within the casing 10. When the rotor 18 is operated to absorb and discharge some powder particles, a specified load is applied to the rotor 18, a relative rotation is performed between the rotary shaft 24 and the shaft 32, a spring 40 is extended to cause a clearance between the lever 36 and the lever 38 to be Y', the rotary shaft 24 is moved with the rotor 18, a position of an end surface of the rotor is moved to the position Y and a proper clearance may be kept.
