High-pressure pump for fuel injection device of internal-combustion engine i.e. diesel engine, has upper concave recess cooperating with corresponding shaping at cylinder head in form-fit manner such that component is pivoted movably

摘要

The pump has an eccentric shaft (2) accommodated in a pump housing (1), and displacing a pump piston (4) to a reciprocating stroke shift, where the shaft is slidingly guided in a cylinder (5). The piston has a piston foot (3) resting at front side of shaft. The front side of the foot is form-fit with the shaft by a lower concave recess (8). The cylinder has an upper concave recess (9) at a head side, where the recess (9) is cooperated with corresponding shaping at cylinder head in form-fit manner such that a component formed of piston and cylinder is pivoted movably with respect to housing.
