DEFINITION

Classification: 222/293

(under subclass 282) Dispensers in which there is a rotor, which is made up of at least two rotor parts, each rotary about the same axis, with means to relatively adjust the same to vary the discharge volume.

(1) Note. These are of two general types, (1) those in which the two rotor parts extend radially about the same axis (including complete annuli) and swing or rotate about such axis for adjustment, and (2) those in which the two rotor parts are axially adjacent or spaced and move axially for adjustment.

(2) Note. A rotor form element must be either (1) symmetrically disposed about the axis of the whole rotor, or (2) mounted on the axial support of the whole rotor.

(3) Note. The adjustment is usually to either change a trap chamber size or to change the size of a material passage through or past the rotor.
