Abstract (en)

[origin: DE19503621A1] The invention is based on a reciprocating pump (10) with two coaxially arranged pistons (12) in which a reciprocating movement can be induced by an eccentric (16) fitted between them and are held against the eccentric (16) by a stirrup spring (28) engaging with the pistons (12). For the purposes of easy fitting, the invention proposes that the stirrup spring (28) take the form of a bent wire section with two open, hook-shaped eyes at their ends inserted in annular grooves (26) in the pistons (12) and forming a snap connection therewith.
