FLUID VALVE AND METHOD FOR CONTROLLING THE SUPPLY OF FLUID
A fluid valve which has a first valve assembly, having a valve needle, and an electromagnetic actuating device is disclosed. The electromagnetic actuating device has an armature, which is coupled to the valve needle, and a pole piece. The armature has on an armature stop side which is opposite the pole piece an armature stop surface, and the pole piece has on a pole piece stop side which is opposite the armature a pole piece stop surface. For advantageous refinement, it is proposed that the first valve assembly has a deformable first ring element and a deformable second ring element, wherein, in a view along the longitudinal central axis, an inner contour of the first ring element extends outside an outer contour of the second ring element. The invention also relates to a method for controlling the supply of fluid by means of a fluid valve according to the invention.
Valve for metering a fluid
A fluid metering valve includes a valve-seat surface; a valve closing element that interacts with the valve-seat surface in order to form a sealing seat; an electromagnetic actuator; a valve needle used for operating the valve-closing element; an armature that is guided on the valve needle and is used for opening or closing the sealing seat; at least one stop that is disposed on, and stationary relative to, the valve needle and that restricts a movement of the armature on the valve needle; and at least one damping element that is configured to provide a damping during the opening or closing of the sealing seat, has a volume that is able to be filled with a fluid medium, is configured such that a fluid medium can be exchanged between the volume and an environment of the damping element, and is configured for volume changes of the volume in order to enable the damping.
