IC engine injection pump fuel feed - involves inlet and air vent pipes connected to annular chamber containing hollow screw extending into immersion pipe

摘要

Installation feeds fuel to the suction chamber of an i/c engine injection pump, and to the single suction chamber connecting holes are connected both the inlet and air venting pipes. Both the inlet pipe(12) and the air venting pipe are connected to a hollow chamber(2) of a ring(3), into which a hollow screw(5) is inserted and screwed into a connecting aperture(8). The screw extends into an immersion pipe(6), and contains several air vent holes(9, 10) issuing into the hollow chamber upper part. The immersion pipe extends into inlet holes(11) issuing into the hollow chamber lower part.
