Abstract
An apparatus (22) for charging a pressurized system (24) comprising a lubricant canister (26). A facility (28) is for fluidly coupling the lubricant canister (26) to the pressurized system (24). An assemblage (30) is for forcing lubricant (32) out of the lubricant canister (26), through the fluidly coupling facility (28) and into a service valve (34) of the pressurized system (24).
Claims16
An apparatus for charging a pressurized air conditioning or refrigeration system with a secondary fluid, comprising:
- a) a canister containing a secondary fluid, wherein said secondary fluid comprises a fluid dye and wherein said canister includes:
- i) a tubular casing for holding the secondary fluid therein,
- ii) a nozzle integral with and extending out from a first end of said tubular casing to engage with one end of a fluidly coupling means, and
- iii) a piston inserted within an open second end of said tubular casing to engage with a secondary fluid forcing means;
- b) means for fluidly coupling said canister to the pressurized system,
- wherein said fluidly coupling means is a connector assembly having a first end connected to said nozzle of said canister and a second end connected to a service valve of the pressurized system,
- wherein said connector assembly includes:
- i) a flexible conduit,
- ii) a thread on a first end of said flexible conduit, to engage with said nozzle of said canister, and
- iii) a release valve on a second end of said flexible conduit, to engage with the service valve of the pressurized system, and
- wherein said connector assembly further includes a valve at one end of said flexible conduit, which prevents any material from back flushing into and contaminating the secondary fluid in said canister;
- and
- c) means for forcing the secondary fluid out of said canister, through said fluidly coupling means and into a service valve of the pressurized system.

- wherein said canister includes a tubular casing for holding the secondary fluid therein, a nozzle integral with and extending out from a first end of said tubular casing and a piston inserted within an open second end of said tubular casing;
- b) means for fluidly coupling said canister to the pressurized system by engagement of one end of said fluidly coupling means to said nozzle,
- wherein said fluidly coupling means is a connector assembly having a first end connected to said nozzle of said canister and a second end connected to a service valve of the pressurized system,
- wherein said connector assembly includes:
- i) a flexible conduit,
- ii) a thread on a first end of said flexible conduit, to engage with said nozzle of said canister, and
- iii) a release valve on a second end of said flexible conduit, to engage with the service valve of the pressurized system,
- wherein said connector assembly further includes a valve at one end of said flexible conduit, which prevents any material from back flushing into and contaminating the secondary fluid in said canister, and
- wherein said release valve includes a closeable valve, which prevents any material from back flushing into said flexible conduit from the service valve of the pressurized system, and to allow said release valve to disconnect from the service valve of the pressurized system, to prevent leakage of the secondary fluid therefrom;
- and
- c) means for forcing secondary fluid out of said canister, through said fluidly coupling means and into a service valve of the pressurized system.
