Patent ID: 7458270

Claim:
An apparatus providing an enclosed passage suitably sized and shaped to conduct a pressurized gas, from a pressurizing source, and introducing it into a pneumatic device, said apparatus comprising: means for attaching the apparatus to the pressurizing source; means for removably attaching the apparatus to the pneumatic device, for the purpose of introducing the pressurized gas into the pneumatic device, the means being attached to the enclosed passage and being positioned with respect to the enclosed passage such that the means for removably attaching the apparatus to the pneumatic device can be removably attached to the pneumatic device when the apparatus is attached to the pressurizing source, to effect the delivery of the pressurized gas into the pneumatic device; means for measuring the gas pressure contained in the pneumatic device, the means for measuring gas pressure being located with respect to the enclosed passage so as to be in sufficient communication with the enclosed passage as to substantially measure the pressure of the gas within the pneumatic device; a valve positioned at a point along the enclosed passage that can be manipulated to interrupt the flow of pressurized gas through the enclosed passage; and the apparatus being arranged such that when the valve is manipulated to interrupt the flow of pressurized gas through the enclosed passage, the pressure of the gas inside the enclosed passage is substantially measured by the gauge, and being further arranged such that when the apparatus is connected to the pneumatic device, but disconnected from the pressurizing source, the valve can be manipulated to allow gas to be released from the pneumatic device through the apparatus.
