| 摘要 |
The present invention relates to a method and apparatus for charging a closed, pressurizable fluid system with an appropriate fluid, comprising a) connecting to the system a closed, unpressurized container containing a predetermined amount of the fluid, b) mechanically forcing the contents out of the container into the system being recharged, and c) disconnecting the container. Preferably, the container is a cylindrical cartridge having a piston sealably disposed therein to displace the cartridge contents. The method and apparatus are effective in recharging various pressurized systems and fluids, such as air conditioning and refrigeration coolant lines, dye injectors, oils, chemicals, glue and the like.
