Abstract
An oscillating armature pump, in particular high-pressure oscillating armature pump, for a household appliance, with a piston guidance for guiding a piston element, with a pump spring provided for supplying an actuation force onto the piston element, and with a housing unit comprising at least one flux-conducting element which is provided to conduct a magnetic flux generated by a magnetic actuator. It is proposed that the flux-conducting element is in a mounted state arranged in a radial direction between the pump spring and the piston guidance.
