Beschreibung
Zusammenfassung:	The invention relates to a spring-loaded nonreturn valve. For ease of production and assembly, a spring element is designed as a leaf spring which is bent in a zigzag shape and is arranged in a transverse groove of a valve closure body. For connection to a spring holder, the leaf spring has a loop with which it is snapped in on a section of the spring holder bent out of wire. The spring holder has a spring ring which is integral with it and is inserted in a groove in a blind bore of a delivery piston, forming a valve housing, of a reciprocating pump.
