Pressure fluid-actuatable camshaft adjustment device for internal combustion engine, has non-return valve assigned to flow channel section through which pressure fluid selectively flows depending on valve body position to chamber

摘要

The device has a cabinet with set of working chambers, pressure fluid pump and a pressure fluid reservoir assigned apertures, by which an outflow of a pressure fluid is enabled. A valve body (11) comprises a flow channel section (8), through which the pressure fluid selectively flows depending on a position of the valve body to one of the working chambers. A non-return valve (9) is assigned to the flow channel section. The channel portion is formed by a radial bore, and a return valve is formed by suction of a hole locking pressure fluid-actuatable closure unit.
