Solenoid valve with reduced cavitation

摘要

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.

1. A solenoid valve, comprising:
a housing including an interior space with a central axis, a valve actuation device including an actuator arranged in the interior space and movable along the central axis, a closing element operatively connected to the actuator to open or close the solenoid valve upon displacement of the actuator along the central axis, a leakage space in the interior space defined by an actuator end face normal to the central axis together with a housing end face facing the actuator end face and the fillable with a fluid flowing between the housing and one or more sides of the actuator, and at least one vortex generator arranged in the leakage space on at least one of the housing end face or the actuator end face and not along lateral sides of the actuator, the vortex generator configured to generate a fluid vortex in the leakage space.
