INJECTOR, CAPABLE OF PREVENTING LEAKS INTO THE ENVIRONMENT, FOR POLLUTANT GASES, PARTICULARLY FOR COOLANT GASES

摘要

An electromagnetic control (12, 14, 14A) causes the opening of a valve (1A) blocking the connector (1) of the system (3) to be used; pipes (30, 34, 42) with corresponding connections to a transfer passage (20, 16, 14B, 9, 7A) are controlled by corresponding valves (36, 38, 44); one of the pipes supplies the refrigerant or other pollutant fluid, a second pipe connects the injector to a vacuum source, and a third pipe connects the injector to a suction recovery means, permitting the discharge, recovery or extraction of pollutant gas from the dead space inside the injector and if necessary from the confined volume of said system (3).
