DEFINITION

Classification: 137/224

(under subclass 223) Apparatus having fluid pressure responsive means permanently associated therewith for controlling the pressure therein or in the inflatable article during the inflating operation or while the inflatable article is in use.

(1) Note. If the pressure responsive control device is associated with the stem and controls the article in use, it does not interfere with the inflation operation.
