Control time setting device for gas-exchange valve of internal combustion engine, has separating element moved in pressure chamber, where pressure-active surface of separating element is continuously movable in region of moving path

摘要

The device has a driven element brought in a drive connection with camshafts (6, 7) of an internal-combustion engine (1) and rotatably arranged to a drive element. A pressure chamber is divided into two counter-acting pressure chambers by a separation element that is movable in the pressure chamber by supplying pressurizing medium to the counter-acting pressure chambers such that a phase position between the driven element and the drive element is changeable. A pressure-active surface of the separating element is continuously movable in a region of a moving path.
