ABSTRACT:
This invention is directed to a sight glass structure positioned in conduit means connecting a suction accumulator and compressor in a refrigeration system. The sight glass structure herein provided may take the form of bushing means rigidly attached to the conduit means and threadably or otherwise receiving an axially passaged sight glass member providing visual communication with the interior of the conduit means, thereby permitting the detection or observation of any slugs of vaporized refrigerant passing from the suction accumulator to the compressor. Another form of the invention includes diametrally opposed bushing means affixed to the conduit means, and each bushing means is similarly equipped with sight glass members of like construction. Either form of the invention, if desired, may include within the sight glass member means impeding movement of the slugs or droplets, thereby improving the detection or observation thereof.
