Abstract
A valve housing for a control valve of a camshaft adjuster, including a housing flange for fastening to a control unit as well as an essentially cylindrical housing component for accommodating a control piston. It is provided that the housing component is rotatably fixedly attached to the housing flange by a form-locked connection. A valve housing of this type is cost effective to manufacture and has a low weight, while ensuring operational reliability. The invention furthermore relates to a method for manufacturing an aforementioned valve housing.
Claims7
A valve housing for a control valve of a camshaft adjusting system comprising:
- a housing flange for fastening to a control unit;
- and
- a cylindrical housing component for accommodating a control piston, the housing component being rotatably fixedly attached to the housing flange by a form-locked connection, wherein the housing flange includes a collar into which the housing component is inserted with a shoulder and wherein the shoulder of the housing component has a plurality of indentations along its outer circumference, via which the housing flange is caulked to the housing component.
A valve housing for a control valve of a camshaft adjusting system comprising:
- a housing flange for fastening to a control unit;
- and
- a cylindrical housing component for accommodating a control piston, the housing component being rotatably fixedly attached to the housing flange by a form-locked connection, wherein the housing component includes a plurality of annular elements spaced an axial distance apart and connected to each other by axial webs.
A method for manufacturing a valve housing for a control valve, the method comprising:
- producing a housing flange for fastening to a control unit;
- producing a cylindrical housing component for accommodating a control piston;
- and
- rotatably fixing the housing component to the housing flange by a form-locked connection, wherein
- the housing flange is produced with a collar, the housing component is produced with a shoulder along whose outer circumference a plurality of indentations are provided, and the shoulder of the housing component is inserted into the collar of the housing flange, and a material of the collar is caulked into the indentations in the shoulder.
