Abstract
A camshaft adjustor (), for an internal combustion engine (), the camshaft adjustor having a stator (), a rotor () which is rotatably accommodated in the stator (), a pressure chamber () for adjusting the rotor () in relation to the stator () and a volume reservoir () for equalizing a negative pressure in the pressure chamber () via a channel () between the pressure chamber () and the volume reservoir (). A non-return valve () having a closure part () for blocking a channel () which opens a volume reservoir () into a pressure chamber () in a camshaft adjustor (), wherein the non-return valve () is formed of a metal sheet and the closure part () is realized so as to be movable in a recess () of the metal sheet () with two oppositely situated ends () which are bent toward each other.
