Fig. 23 Advance piston location
The hydraulic timing-advance device is built into the distributor pump's underside, at right angles to the pump's longitudinal axis; the timing piston is
guided by the pump housing, Fig. 23. The housing is sealed by a cover at both sides. On one side of the piston is a fuel inlet bore, on the other side a
spring. A sliding block and an actuating pin connect the piston with the roller ring.
