ABSTRACT:
The delivery system functions under pump pressure to introduce a fluid such as a tire sealant interiorly of a pneumatic vessel such as a tire through the air valve without deflating the vessel. A valve core extractor functions in a pressurized atmosphere to remove and retain the valve core without loss of pressure. A pump including a resilient, one way check valve introduces the fluid through the valve, also without loss of pressure. Following introduction of the desired quantity of the fluid, the valve core extractor is functioned in reverse to reinsert the valve core, all without loss of system pressure.
