Abstract:
1. Device for the variable adjustment of the control times of gas-exchange valves of an internal combustion engine, comprising a stator and a driven element arranged coaxial to the stator, wherein the stator and the driven element are mounted so that they can rotate relative to each other and at least one pressure space bounded by the stator and the driven element at least in a radial direction and in a circumferential direction, a housing, which is constructed separate from the stator and the driven element and which at least partially encapsulates the stator and the driven element, the housing includes a pot-shaped first housing element with at least one flat section of the first housing element that extends perpendicular to the axial direction of the device to act as a sealing surface for the pressure space and bounds the pressure space in a sealing manner in a first axial direction, and an outer circumferential wall that entirely surrounds a radial periphery of the stator and the driven element for an entire axial depth thereof, and a second housing element that defines and seals the pressure space in a second axial direction.
