A camshaft adjustor (4), for an internal combustion engine (2), the camshaft adjustor having a stator (20), a rotor (22) which is rotatably accommodated in the stator (20), a pressure chamber (44) for adjusting the rotor (22) in relation to the stator (20) and a volume reservoir (70) for equalizing a negative pressure in the pressure chamber (44) via a channel (88) between the pressure chamber (44) and the volume reservoir (70). A non-return valve (72) having a closure part (102) for blocking a channel (88) which opens a volume reservoir (70) into a pressure chamber (44) in a camshaft adjustor (4), wherein the non-return valve (72) is formed of a metal sheet and the closure part (102) is realized so as to be movable in a recess (98) of the metal sheet (92) with two oppositely situated ends (94, 96) which are bent toward each other.
A camshaft adjustor, for an internal combustion engine, said camshaft adjustor comprising 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 by via a channel between the pressure chamber and the volume reservoir, and a non-return valve having a closure part for blocking the channel which opens the volume reservoir into the pressure chamber in a camshaft adjustor, the non-return valve is formed of a metal sheet in which a closure part is provided so as to be movable in a recess of the metal sheet with two oppositely situated ends which are bent toward each other.
