Polygon pump, especially a single cylinder fuel injection pump for air-sealed self-ignition motors, has two flats on the polygon ring for supports with a sprung link between them

摘要

The polygon pump (1), especially a single cylinder pump for fuel injection in air-sealed self-ignition internal combustion motors, has a polygon ring (14) sliding on the eccentric section (8) of a drive shaft (3) with a flat (15) for the piston (10) support (12). The polygon ring has a further flat (25) for an additional support (26), with a sprung link (31) to the first support.
