摘要：A device () for variably adjusting the control times of gas exchange vales () of an

internal combustion engine () having a hydraulic phase adjustment device () and at leastone volume accumulator (), wherein the phase adjustment device () can be brought intodriving connection with a crankshaft () and a camshaft () and at least one early adjustmentchamber () and at least one late adjustment chamber () which can be supplied withpressure medium via pressure medium lines (), or from which pressure medium can bedrained. A phase position of the camshaft () can be adjusted relative to the crankshaft () inthe direction of early control times by supplying pressure medium to the earlyadjustment chamber () while simultaneously draining pressure medium from the lateadjustment chamber (), wherein a phase position of the camshaft () can be adjustedrelative to the crankshaft () in the direction of late control times by supplying pressuremedium to the late adjustment chamber () while simultaneously draining pressuremedium from the early adjustment chamber (), wherein pressure medium can be suppliedto the volume accumulator(s) () during operation of the internal combustion engine ().
