<p>A system for controlling, containing and removing residual cleaning solvent vapors from a drycleaning machine which includes actuator valves (10a, 10b, 10c, 10d) positioned in each of the cleaning solvent supply and removal lines (6, 7) and in each of the drying air supply and solvent vapor removal lines (8, 9). The actuator valves are positioned as close to the machine cylinder (2) as possible to eliminate dead space in the respective lines. Isolation of residual vapor is achieved by closing all the actuator valves. Thereafter, an exhaust system (12) is actuated as the machine door (4) is opened to remove residual cleaning solvent vapors.</p> |
