US Patent 12092237 Chuck for airpump

A chuck for inflating a tire having a valve includes a valve engagement device having a longitudinal axis, a first portion and a second portion that move laterally with respect to the longitudinal axis and in parallel with each other to define a chamber for receiving the valve stem. An actuator that moves longitudinally with respect to the valve engagement device causes the first portion and the second portion to move laterally and in parallel. The first portion and the second portion of the valve engagement device include protrusions, and the actuator contacts the protrusions as the actuator is moved longitudinally.
