摘要：The invention relates to a device (1) for changing the control times of gas exchange valves in an internal combustion engine, comprising a component (4), driven by one of the crankshafts of the internal combustion engine and fixed to the same and a component (5) driven by a camshaft (3) and fixed to the same. The component (4) fixed to the crankshaft is connected to the component (5) for power transmission by means of at least two pressure chambers formed within the device (1), which on pressurisation cause a relative rotation or a hydraulic adjustment of the component (5) fixed to the camshaft, relative to the component (4) fixed to the crankshaft. Furthermore, the device (1) comprises an impulse generator wheel (12) connected to the component (5) fixed to the camshaft, for determining the position of the camshaft and a spring (13) connected to both the component (4) fixed to the crankshaft and the component (5) fixed to the camshaft, for turning the camshaft into a preferred position for starting the internal combustion engine. According to the invention, the spring is arranged in a cavity (15) formed between the impulse generator wheel (12) and the opposite axial side (10 or 11) of the device (1) and enclosed on at least two sides by the impulse generator wheel (12).
