Abstract:
A control valve for a camshaft adjuster for an engine is provided. The control valve includes a valve sleeve having one or more inlet openings, two supply openings, and an outlet opening, and a control piston guided in the valve sleeve. The piston, together with the valve sleeve and control edges arranged on the control piston, form three annular ducts. A fluid-conducting connection between an inlet opening and a supply opening can be controlled via a first annular channel. A fluid-conducting connection between the inlet opening and another supply opening can be controlled via a second annular channel. The first annular channel and the second annular channels may enclose a central annular channel, via which a fluid-conducting connection between the supply opening and the outlet opening, as well as between the another supply opening and the outlet opening, can be controlled.

Claim (Index 11):
A camshaft adjuster comprising:\n a valve housing extending along an axis and defining a valve inlet opening at one axial end thereof, a first housing supply opening, a second housing supply opening, and a housing outlet opening; a valve sleeve within the valve housing having a sleeve inlet opening, a first sleeve supply opening, a second sleeve supply opening, and a sleeve outlet opening; and a control piston slideable along the axis within the valve sleeve and guided by the valve sleeve, wherein the piston is slideable from a first axial position to a second axial position relative to the valve sleeve and valve housing, wherein the piston and the valve sleeve combine to form a first annular duct, a second annular duct, and a third annular duct; wherein when the control piston is slid from the first axial position to the second axial position:\n a first fluid connection is made between the housing inlet opening, the sleeve inlet opening, the first housing supply opening, the first sleeve supply opening, and the first annular duct, and \n a second fluid connection is made between the second housing supply opening, the second sleeve supply opening, the third annular duct, the sleeve outlet opening, and housing outlet opening.
