Abstract
A system for use in servicing and installing refrigeration systems without freon leakage comprising a connector, the connector having a first extent with an outboard end and an inboard end, the connector also having a pair of second extents, each with an outboard end and an inboard end, the inboard ends of the first and second extents being coupled together for the passage of fluid therethrough, and a radial aperture formed in an intermediate region of the first extent.
Claims2
A new and improved system for use in servicing and installing refrigeration systems without freon leakage comprising, in combination:
- a connector in a generally Y-shaped configuration, the connector having a central linear extent with an outboard end and an inboard end, the connector also having a pair of parallel linear extents, each with an outboard end and an inboard end, the inboard ends of the central and parallel extents being coupled together for the passage of fluid therethrough, and a radial aperture formed in an intermediate region of the central linear extent;
- a rotatable fitting attached between the central extent at the outboard end and a hose attached to the refrigeration system to be serviced for allowing passage of fluid between the connector and refrigeration system;
- a pair of supplemental rotatable fittings, each attached between one parallel extent at the outboard end and a tank constituting a source of refrigerant for allowing passage of fluid between he tank and connector;
- an additional rotatable fitting attached between the aperture of central extent and a hose attached to a source of vacuum for allowing passage of air between the connector and source of vacuum;
- and
- a plurality of manually operated valves adapted to open and close the flow of fluid therethrough, a first valve being operatively coupled adjacent to the outboard ends of each parallel extent for controlling the flow of fluid and air between the tank and the connector and a second valve operatively coupled adjacent to the additional rotatable fitting for controlling the flow of fluid and air between the source of vacuum and the connector.
