Device for pumping fuel

摘要

The injector pump (1) has two drive air nozzles (2) side-by-side in a common nozzle body (1.2) in a common cone (31,33). The air and fuel enter two separate mixing pipes (3) side-by-side. On leaving the mixing pipes the air-fuel mixture enters a diffuser cone (25). Fuel is drawn from a tank (8) into a space (22) between a cylindrical entrance portion (21) and the nozzle body. The air supply has a preliminary filter (18), a pump (15) driven by the internal combustion engine (16), and a main filter (19). The air flows through a pressure control valve (11).
