Abstract (en)

[origin: US2011005482A1] A device for variably adjusting control times of gas exchange valves of an internal combustion engine. The device has a drive element, an output element, a rotation angle limiting device, a control valve and counter-working pressure chambers. Phase adjustment between the output and drive element is initiated by applying pressure to one of the pressure chambers while discharging the other pressure chamber. The rotation angle limiting device, which can be transferred from a locked state into an unlocked state due to pressure, prevents phasing when locked and allows phasing when unlocked. The control valve has a valve housing and a control piston. An inflow connection, an outflow connection, a first and a second working connection and a third working connection are embodied on the valve housing. The working connections are offset in relation to other and do not overlap on the valve housing.
