DEFINITION

Classification: 239/88

(under the class definition) Apparatus which includes an injection nozzle having an expansible and contractible chamber intimately and contiguously associated therewith and adapted to deliver fluid intermittently through the nozzle in response to contraction of the chamber.

(1) Note. The chamber collapsing means may be a resilient biasing member or a motor driven means provided that there is no more than a nominal recitation of a motor of which the nozzle forms a part.

(2) Note. Expansible chambers formed by pressure responsive surfaces formed on, or connected to a valve or valve stem have been excluded from this and the indented subclasses even though these chambers may deliver a small amount of fluid to the nozzle during closing movement of the valve.
