摘要： 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.

摘要： An apparatus and method for preventing an undesirable release of fluid from a conduit upon disconnection of the conduit. In a specific form of the invention, the apparatus includes a hose having a slide valve located therein adjacent an end of the hose for preventing the escape of liquids or gases, especially refrigerants, to the environment. The slide valve includes a substantially cylindrically shaped nipple having first and second bores extending axially therethrough, the first and second bores being divided and bounded by an integral wall of the nipple. The nipple includes a plurality of ports adjacent the integral wall which provide passages through the nipple to provide fluid communication between the first and second bores. A sleeve member is slidable disposed around the nipple and contains seals for providing a gas-tight and/or liquid-tight interface between the sleeve and the nipple. The sleeve member also includes an annular chamber for selectively providing the aforementioned fluid communication between the bores. A preferred embodiment of the invention includes a conduit having a threaded screw type valve which includes a substantially cylindrically shaped rear nipple emanating from its first end, having a central bore extending therethrough. The rear nipple is exteriorly threaded to a threaded valve body which, when rotated is capable of sealing and unsealing a valve set with a valve fitting for selectively opening and closing a passageway for the flow of liquid an/or gas from the rear nipple to a front nipple. The front nipple is capable of rotating with respect to the rest of the device without breaking its seal and can be removed and interchanged without a substantial loss of fluid.

摘要： A flushing unit for flushing vapor compressions systems with a flushing agent. The flushing unit includes a pressure relief member to ensure that the reservoir containing the flushing agent is not over-pressurized. In certain embodiments, the flushing unit is adapted to be in communication with a driving fluid or propellant, such as an inert gas or a flushing gas, and with a source of a flushing agent, such as a reservoir. The flushing unit includes a valve that, when opened, causes the driving fluid to flow into the reservoir containing the flushing agent and displace the flushing agent from the reservoir, causing it to ultimately flow into the system being flushed such as via a suitable hand-held injector. In the event the pressure in the reservoir exceeds a predetermined level, a pressure relief valve in the flushing unit is automatically actuated, thereby relieving pressure in the otherwise closed system.
