20140265317 | High Pressure Fitting - A fitting, such as an anti-blowback fitting, that includes a friction reducing device that enables easy removal of the fitting from a high pressure connection such as one associated with an HVAC unit. When used in connection with refrigeration, anti-blow back fittings function to keep the refrigerant in the hose to which it is connected in order to minimize or prevent the refrigerant from escaping to the environment. In certain embodiments, a friction reducing device is positioned in the fitting, and decreases the load on the rear housing, which enables easy rotation of the outer or swivel housing of the fitting to remove the same from the high pressure connection. In certain embodiments, the friction reducing device is a thrust bearing. | 09-18-2014 |
20120023972 | Refrigerant Charging Tool And Method - Gas vaporizer for flashing liquid to vapor received from a source prior to introduction into a compressor or the like, such as in air conditioning or refrigeration systems. In certain embodiments the vaporize includes an adapter member for connection to a liquid source, a connector member having a plurality of flow passages for facilitating the transfer of heat to fluid present therein to vaporize the same, a body portion providing visual access such as via one or more sight glasses to an internal chamber therein for visual confirmation that liquid has been vaporized, and a hose connecting member for connection to a point of destination such as a compressor. In certain embodiments, the connector has an axial bore containing a high thermal conductive material. | 02-02-2012 |
