Abstract
This invention involves an apparatus for vapor containment and recirculation for use in fluid systems, including pumps and valves. More specifically, this invention provides a closed loop recirculation system for ensuring that vapor does not escape from fluid systems. The invention comprises a vapor containment gland comprising a vapor channel; a suction manifold attached to the vapor containment gland and comprising a suction channel, a fluid injection channel, and a suction nozzle bore; a suction nozzle insertable in said suction nozzle bore and comprising a flow channel in fluid communication with said fluid injection channel and said suction channel; and a fluid injection recirculation line attachable to said suction nozzle.
