Abstract

A solenoid valve includes a housing, a valve actuation device, and a closing element, wherein the housing includes an interior space with a central axis, wherein the valve actuation device includes an actuator arranged in the interior space so as to be displaceable along the central axis, wherein the actuator is operatively connected to the closing element such that the solenoid valve is opened or closed by a displacement of the actuator along the central axis, wherein the actuator together with the housing delimit, in the interior space of the housing, a leakage chamber that can be filled with a fluid, e.g., a fuel, and wherein in the leakage chamber, at least one vortex generator is arranged on the housing and/or on the actuator, which vortex generator is configured to generate a fluid vortex in the leakage chamber.
