Abstract

A liquid injector has a tubular body (11) surrounding and shielding a glass tube (7). The body and tube are sealed at opposing ends by a valve coupler (3) and an end fill cap (13), each with their own O-ring seals. There are three openings (41) through the body to allow for viewing of the contents of the tube, and to allow for light to pass into the tube. The injector is connected at the valve coupler through a hose and an on-off valve to the low side of an air conditioning system. It is connected through the end fill cap to a refrigerant charging system. The valve is shut off and the end fill cap is removed. The body is held upright and the liquid to be injected is poured into the glass tube. The fill end cap is replaced and the valve turned on. The charging system propels the liquid into the air conditioning system. The tube can be viewed through the openings to determine that a sufficient quantity of the liquid has been propelled from the injector. A supplemental reservoir for combination with an inline end fill injector has a receptable providing a chamber with opposing threaded apertures.
The threads match those of the body and the fill cap, respectively.
The receptacle can be provided as an adaptor wind base combination.
The receptacles can be provided in different sizes by changing the size of the adaptors. This provides for different size injectors without having to use a different injector for each desired size.
