5000,S Turbo Diesel L5-1986cc 2.0L DSL SOHC Turbo (DE) (1982)
The impeller's four vanes, Fig. 14, are forced outward by centrifugal action against the eccentric ring; this motion is reinforced by the fuel between the
vanes' undersides and the impeller. Fuel moves through the inlet port in the injection pump's cavity and a kidney shaped recess in the space formed by
the impeller, vane and eccentric ring. The rotary motion causes the fuel between adjacent vanes to be forced into the upper kidney-shaped recess and
through a bore into the pump cavity. Simultaneously, a portion of the fuel flows through a second bore to the pressure-control valve.
