Beschreibung
Zusammenfassung:	A control valve for a pump for delivering a fluid. The control valve includes: a valve housing which delineates a piston chamber; a piston which can be moved within the piston chamber; and a fluid channel which ports into the piston chamber via a port opening, wherein the port opening defines a port control edge. The valve housing includes a recess which extends into the fluid channel, wherein the recess defines a recess control edge which is axially offset with respect to the port control edge, and/or the piston includes a piston recess which defines a piston recess control edge.
