DEFINITION

Classification: 494/23

WITH MEANS FOR FURNISHING AUXILIARY FLUID TO MATERIAL OR APPARATUS:

(under the class definition) Apparatus provided with means for introducing, or for facilitating the introduction of, one or more fluids, which fluid or fluids are not initially a part of the material intended to undergo separation, to the material or to one or more components or elements of the separator.

(1) Note. While not constituting a portion of the material as supplied for separation, the fluid of this subclass sometimes becomes an indistinguishable part of either that material or a separated component thereof.

(2) Note. Included in this and the indented subclasses, especially subclasses 27+ is the introducing of a fluid for a cleaning purpose.

(3) Note. Suction is not considered to be the introduction of a fluid within the concept of this and the indented subclasses; note, however, that suction for the purpose of reducing the pressure in a housing for a bowl is provided for in subclass 61 below.

(4) Note. The furnishing of a fluid for actuating a component (e.g., a valve) of the separator is included in this and the indented subclasses.
