摘要:
A valve system for use in inflating packers mounted on mandrels is disclosed. The valve system uses one valve to permit, through the use of seals, the flow of fluid from the interior of a tubular mandrel to the interior of the inflatable packer when pressure applied in the mandrel exceeds at least a minimum pressure.
