Embodiment Construction

[0029] figure 1 Shown is an injection valve 1 known from the prior art, such as, for example, an injection valve for injecting fuel into an intake port or a combustion chamber of an internal combustion engine.

[0030] Injection valve 1 has a fluid inlet port 1 a and a fluid outlet port 1 b and comprises a valve housing 2 surrounding a cavity 3 . The valve needle 4 is arranged in the cavity 3 . The valve needle 4 is displaceable along the axis A relative to the valve housing 2 . On its end facing the fluid outlet port 1 b of the injection valve 1 , the valve needle 4 has a closing element 5 in the form of a ball, with which the valve needle 4 can be accommodated in a valve seat 6 . The valve seat 6 has an opening 7 which can be opened or closed by the closing element 5 of the valve needle 4 . If the valve needle 4 is moved into its position which opens the opening 7 , the fluid for metering can exit the injection valve 1 through the opening 7 . If valve needle 4 is in its ...

Abstract

The invention relates to a laminated solenoid armature (10) for an electromagnetic activation device, wherein the solenoid armature (10) can be shifted in a direction of movement along an axis A, comprising a multiplicity of laminations (14) which are connected to one another, wherein the laminations (14) are oriented perpendicularly with respect to the axis A and are stacked in the direction of movement of the solenoid armature (10) to form a lamination stack with an underside and an upper side, and wherein each lamination (14) has at least one recess (16) which is open towards an edge (17) of the lamination (14), wherein the laminations (14) are arranged inside the lamination stack in such a way that the recesses (16) form at least one duct (18) which passes through the lamination stackfrom the underside to the upper side. The invention also relates to an injection valve for metering a fluid, comprising an electromagnetic activation device having such a laminated solenoid armature (10).

Description

technical field [0001] The invention relates to a laminated magnet armature for an electromagnetic actuation device and to an injection valve for metering fluids comprising an electromagnetic actuation device with a laminated magnet armature of the type described . Background technique [0002] Injection valves are used for the controlled metering of fluids, for example fuel, into the intake port or combustion chamber of an internal combustion engine. The injection valve can be controlled by means of an electromagnetic actuating device, which for this purpose has an electrically excitable coil and has a magnet armature made of ferromagnetic material. When a voltage is applied to the coil, a magnetic field is formed in the interior of the coil, by means of which the ferromagnetic magnet armature is able to move. Coupled to the magnet armature is the valve needle, which, by means of the magnetic interaction between the coil field and the magnet armature, can move to a positi...
