Patent ID: 8511522

Claim:
A valve, comprising: (a) a plug comprising a plug first end, a plug second end, a blind hole created within the plug that extends from the plug first end to a blind hole bottom and that is spaced apart from the plug second end, a plug side wall extending radially outwardly from the blind hole to an outer surface of the plug and a flow passage that extends through the plug side wall that is either open or openable; and (b) a tube that is partially disposed within the blind hole, the tube comprising an internal channel, at least one open end that is in fluid communication with the internal channel, a tube sidewall extending radially outwardly from the internal channel to an outer surface of the tube, and a tube hole extending through the tube sidewall, wherein the plug has at least one section having an outer diameter that is elastically deformable and elongatable lengthwise so that the outer diameter of the plug in the at least one section decreases when the plug is elastically deformed in the presence of a normal force that is applied to the plug via the tube.
