Reciprocating piston pump for supplying fluid, particularly fuel or fuel additive for internal-combustion engine for fluid supply system, has supply area with inlet opening and outlet opening

摘要

The reciprocating piston pump (1) has a supply area (2) with an inlet opening (3) and an outlet opening (8). A magnetic actuator (10) is pre-stressed by a spring element (14) in a direction of the inlet opening or outlet opening. A valve seat is turned by the inlet opening and outlet opening of the supply area. An independent claim is included for a fluid supply system, particularly a fuel or a fuel additive for an internal-combustion engine.
