Electrohydraulic valve and method for producing the electrohydraulic valve

Abstract

An electro hydraulic valve for a cam phaser, including an electromagnetic actuator assembly, and a hydraulic assembly, wherein the electromagnetic actuator assembly and the hydraulic assembly are arranged axially aligned along a longitudinal axis, wherein the hydraulic assembly includes a valve housing in which a valve piston is arranged axially movable along the longitudinal axis, wherein a plunger for positioning the valve piston along the longitudinal axis is arranged within the electromagnetic actuator assembly, and wherein the electromagnetic actuator assembly and the hydraulic assembly are connected with one another indirectly or directly, wherein the electromagnetic actuator assembly includes an actuator housing and a friction or form locking connection of the electromagnetic actuator assembly with the hydraulic assembly is provided by an ultrasonic weld between the actuator housing and the valve housing.

Dependencies are inferred from the claim text.
