[2J FUEL FEED PUMP
The filtered fuel is fed to the injection pump by the fuel fed
pump.
The chamber (1) is enclosed with the inlet valve (2), the out­
let valve (5) and the diaphragm (6), which is linked to the
rocker arm with the pull rod (7). The rocker arm is swinged
by the eccentric cam on the fuel camshaft (4).
When the diaphgram is pulled down, vaccum in the chamber
(1) causes the outlet valve (5) to close and the atomospheric
pressure in the fuel tank to force the fuel into the chamber,
opening the inlet valve (2).
When the diaphragm is pushed up by the cam, the pressure in
the chamber causes the inlet valve to close and forces out the
fuel, opening the outlet valve.
