Definitions
- an at least simply slotted target ring formed as a separate, prefabricated part and attached to the outer circumference of the plunger is made of a material based on Fe or a ferritic material.
- a target ring which is based on Fe or made of a ferritic material, can be used to use a sensor that operates at lower frequencies than a target made of copper.
- the signal quality can also be increased in that the target ring consists of a separate, prefabricated part. This means that the target ring is not attached to and after being attached to the plunger more thermally stressed than would be the case, for example, with melting application, in which the conversion process would occur in the material of the target ring, which would change its magnetic properties.
- the actuator 14 comprises two electromagnets 16, 18 through which an armature or, more generally, a plunger 20 extends, which is connected at its lower end to the valve stem 22, so that the axial, oscillating movement of the plunger 20 is immediate a corresponding movement of the lift valve 12 causes.
- the axial movement of the plunger 20 should be path-controlled, which is why the position of the plunger must be determined as precisely and quickly as possible.
- An inductive sensor 24 surrounding the plunger and operating at low frequencies is provided for determining the position of the plunger 20. Radially inward of the sensor 24, a target ring 26 is fastened in a circumferential groove in the plunger 20 without play or gap. The sensor 24 determines the position of the target ring 26 and thus of the tappet 20 and the lift valve 22.
- the target ring 26 consists of two ring segments 34, 36 which are simply inserted from the radially outside onto the tappet, more precisely into the circumferential groove which forms the outer circumference in sections.
- the segments, more precisely cylinder half-shells, 36 and 38 can also be fastened to one another or in the circumferential groove by welding, soldering or gluing or by the shaping methods which will be explained later.
