Actuator for cam phaser and cam phaser

Abstract

An actuator for a cam phaser, the cam phaser including a hydraulic valve that is adjustable by the actuator, wherein the actuator is receivable at a housing section of a component that receives the cam phaser, wherein the actuator includes a retaining element and a housing with functionally relevant components, wherein the actuator is attached by the retaining element at the housing section, wherein the retaining element is configured separate from the housing, wherein safe positioning of the actuator at the housing section is provided by a section of the retaining element that supports the actuator at the housing section in a direction of an axial orientation of the actuator, and wherein a housing cover of the housing is at least partially arranged between the section of the retaining element and the housing section.

What is claimed is: 
     
         1 . An actuator for a cam phaser, the cam phaser comprising:
 a hydraulic valve that is adjustable by the actuator,   wherein the actuator is receivable at a housing section of a component that receives the cam phaser,   wherein the actuator includes a retaining element and a housing with functionally relevant components,   wherein the actuator is attached by the retaining element at the housing section,   wherein the retaining element is configured separate from the housing,   wherein safe positioning of the actuator at the housing section is provided by a section of the retaining element that supports the actuator at the housing section in a direction of an axial orientation of the actuator, and   wherein a housing cover of the housing is at least partially arranged between the section of the retaining element and the housing section.   
     
     
         2 . The actuator according to  claim 1 , wherein the housing cover and the retaining element are arranged in an alternating manner along a circumference of the housing as an outer boundary that is oriented away from the housing section. 
     
     
         3 . The actuator according to  claim 1 , wherein the retaining element is at least partially complementary to the housing. 
     
     
         4 . The actuator according to  claim 1 , wherein the retaining element envelops the housing essentially along circumference of the housing and along an enveloping surface of the housing. 
     
     
         5 . The actuator according to  claim 1 , wherein the retaining element receives the housing in a form locking manner. 
     
     
         6 . The actuator according to  claim 1 ,
 wherein the retaining element includes a contact surface that is arranged transversal to a receiving direction of the actuator, and   wherein the contact surface is arranged opposite to and in contact with a housing surface.   
     
     
         7 . The actuator according to  claim 1 ,
 wherein a snap locking element is arranged at an enveloping surface of the housing,   wherein the snap locking element is configured to prevent a movement of the retaining element in the axial direction.   
     
     
         8 . The actuator according to  claim 1 , wherein the retaining element is configured to receive a positioning element that is arranged at the housing. 
     
     
         9 . The actuator according to  claim 1 , wherein the retaining element receives a plug-in device of the actuator at least partially. 
     
     
         10 . The actuator according to  claim 1 , wherein the retaining element is configured as an injection molded component. 
     
     
         11 . The actuator according to  claim 9 , wherein the retaining element includes an electrical connection of the plug-in device. 
     
     
         12 . The actuator according to  claim 1 , wherein the retaining element is attachable at the housing section in a disengageable manner. 
     
     
         13 . The actuator according to  claim 1 , wherein the retaining element is configured as a frame. 
     
     
         14 . The actuator according to  claim 1 , wherein the housing section is a section of a cylinder head of an internal combustion engine. 
     
     
         15 . A cam phaser, comprising: the electromagnetic actuator according to  claim 1 .
