Valve cartridge for an adjustable valve, and associated solenoid valve

摘要

A valve cartridge has a capsule and a valve insert, which is connected to the capsule by way of a first end and has a valve body with a main valve seat at the other end. A plunger is movably guided within the valve cartridge, it being possible for the plunger to move against the force of a return spring and the plunger having a closing element with a sealing element that interacts with the main valve seat of the valve body in a sealing manner to provide a sealing function. A corresponding solenoid valve has a valve cartridge of this kind. A magnetic damping assembly has a permanent magnet and an electrical conductor which is arranged in the magnetic field of the permanent magnet and is coupled to the moving plunger and can be moved substantially perpendicular to the magnetic field.

1. A valve cartridge comprising:
a capsule having a first end; a valve insert inserted into the capsule at the first end and including a valve body with a main valve seat; a plunger movably guided for axial movement within the capsule toward the valve seat, said plunger being configured to be moved against a force of a return spring and having a closing element with a sealing element; and a magnetic damping assembly, wherein the sealing element interacts with the main valve seat of the valve body in a sealing manner to provide a sealing function, wherein the magnetic damping assembly has (i) a permanent magnet positioned outside the capsule and configured to generate a magnetic field and (ii) an electrical conductor positioned in the capsule in the magnetic field of the permanent magnet, the electrical conductor being coupled to the plunger for axial movement therewith within the capsule, the permanent magnet being configured to generate the magnetic field such that the magnetic field in which the electrical conductor is positioned is perpendicular to the axial movement of the electrical conductor in the capsule.
