Patent ID: 6837270

Claim:
A pneumatic yoke for a pressurized gas reservoir, the yoke comprising: (a) an aperture for receiving a stem of the pressurized gas reservoir, the stem having a stem valve selectively operable to permit a flow of pressurized gas through an opening of the stem; (b) a gas passage for alignment with the opening of the stem to accept the flow of pressurized gas; (c) a gas diverting conduit in fluid communication with the gas passage; (d) a movable clamping member within the gas diverting conduit, the movable clamping member having a surface forming a boundary of the conduit, the boundary displaceable by a flow of gas into the conduit to thereby vary the volume of the conduit to thereby engage the clamping member with the stem; and, (e) a release valve in fluid communication with the gas diverting conduit, the release valve selectively operable to permit a flow of gas from the conduit to permit disengagement of the movable clamping member with the stem.
