Abstract

The invention relates to a device (11) for variably adjusting the control times of gas exchange valves (9, 10) of an internal combustion engine (I) having a hy¬draulic phase adjustment device (12) and at least one volu¬me accumulator (31), wherein the phase adjustment device (12) can he brought into driving connection with a cranks-haft (2) and a camshaft (6, 7) and at least one early adjust¬ment chamber (24) and at least one late adjustment cham¬ber (25) which can be supplied with pressure mediums via pressure medium lines (26a, b, p, v), or from vhich pres¬sure mediums can be drained. A phase position of the camshaft (6, 7) can be adjusted relative to the orankshaft (2) in the direction of early control times by supplying pressure mediums to the early adjustment chamber (24) while simultaneously draining pressure mediums from the late adjustment chamber (25), wherein a phase position of the camshaft (6, 7) can be adjusted relative to the cranks¬haft (2) in. the direction of late control times by supplying pressure mediums to the late adjustment chamber (25) while simultaneously draining pressure mediums from the early adjustment chamber (24), wherein pressure mediums can be supplied to the volume accumulator(s) (31) during operation of the internal combustion engine (1).
