High integrity dispensing of two-stroke fuel

摘要

The fuel and oil are withdrawn from supply tanks (1,2), by the pump units (9,18), supplying a common delivery pipe (14) via individual, linked, positive displacement meters (11,21) equipped with an adjustable regulator (25). A recycle line (28) with a relief valve (29) returns from the oil pump outlet (18) back to its tank. In parallel with this, just before the oil metering piston, a gas release nozzle (32) branches off.
