Abstract

A device (1) for the variable adjustment of control times of an internal combustion engine, including a stator (2), a driven element (3) arranged coaxially thereto, with both components being assembled so as to rotate relative to one another, and both components define at least one pressure chamber (10) at least in the radial and circumferential directions, and a housing (11), separate from the stator (2) and the driven element (3) which encloses the stator (2) and the driven element (3) in an oil-tight manner, whereby the housing (11) seals and defines the pressure chamber in an axial direction.
