Abstract

The invention relates to a method for operating a piston pump, which is driven by means of a coil (1) of an electromagnet, wherein a piston (2) of the piston pump can be moved against a restoring force by means of the electromagnet, wherein a voltage (U) is applied to the coil (1) during a switch-on duration such that a current (I) flows through the coil (1) and the piston (2) is accelerated, wherein two different quenching methods are used for the current (I) in the coil (1).
