Abstract:
An apparatus for use with a charging system and a pressurized air-conditioning system for urging fluid from the charging system into the pressurized system, the charging system initially containing the fluid held under pressure, the charging system having a chamber therein for holding a propellent and the fluid, and having a first pressure-actuated valve assembly mounted within an opening in the charging system to the chamber, the first valve assembly having a first valve and a rigid discharge tube connected to the first valve, the discharge tube being retractable to actuate the first valve to release the fluid from the charging system, the pressurized system having an R-134A fitting and a second pressure-actuated valve assembly mounted within the fitting, the second valve assembly having a second valve and a pin connected to the second valve, the pin being retractable to actuate the second valve to allow entry of the fluid into the pressurized system, the apparatus comprising:a rigid structure having: a first end for connecting to the aerosol dispenser charging system and a second end for connecting to the R134A fitting of the pressurized system; a conduit defined within the structure extending between the first end and the second end; the conduit being adapted to receive the discharge tube at the first end; a stop disposed within the conduit; a first seal disposed within the conduit for discouraging leakage of fluid between the structure and the discharge tube of the first valve assembly when the charging system is connected to the structure; a rigid depressor; the depressor being mounted at the second end of the structure clear of the conduit so as not to prevent the egress of fluid therefrom; and a resilient second seal mounted within the structure for sealing between the structure and the fitting when the structure is connected to the pressurized system; and wherein, the stop is for urging the discharge tube of the first assembly to retract, and the rigid depressor is for urging the pin of the second valve assembly to retract, when the charging system and the pressurized system are connected to the adaptor and force is applied to the charging system toward the pressurized system.
