An injection device () injects a dispensable fluid material (), for example, a liquid sealant, into refrigerant lines of an air conditioning or refrigeration pressurized system, by utilizing the pressure difference between high and low pressure zones of the pressurized system. The device comprises a tube () which contains the dispensable fluid material () and is closed by an outlet valve (). A movable member () houses a spring-loaded check valve () and is disposed downstream of and spaced from the outlet valve (). The movable member () is movable within a passageway () formed in an outlet tube connector (). Upon being connected to a service port () of a pressurized system by an installation nut (), movable member () is forced into engagement with the outlet valve () to open it to dispense fluid material () into service port ().

Fluid material injection device

A fluid injection device () for injecting a dispensible fluid material (), e.g., a liquid sealant, into refrigerant lines of an operating air conditioning or refrigeration system or the like, includes a tube () having at its outlet end a fluid outlet valve () is closed by a valved plug () to provide therebetween an airlock chamber () containing a dried inert gas which prevents reaction, e.g., polymerization, of any liquid sealant which has leaked past the fluid outlet valve () prior to use of the device. The device () is used by removing the valve plug () just prior to use and connecting the outlet valve () to a low pressure zone of the system and then connecting an inlet closure member () to a high pressure zone of the system while the system is in operation. A method of making the device includes displacing air from the device with the inert gas and then introducing the materialinto the tube.
