Abstract
An apparatus (10) for the variable setting of control times of gas-exchange valves (9a, b) of an internal combustion engine (1) is provided and includes a drive element (22), a driven element (23), at least one pressure chamber (35, 36), a pressurized medium system (37), and a pressure storage device (43). The pressure chamber (35, 36) and the pressure storage device (43) communicate with the pressurized medium system (37), and a phase position between the driven element (23) and the drive element (22) can be changed by supplying pressurized medium to or discharging pressurized medium from the pressure chamber (35, 36) by the pressurized medium system (37).
Claims8
An apparatus for the variable setting of control time of gas-exchange valves of an internal combustion engine, comprising
- a drive element, a driven element, at least one pressure chamber, a pressurized medium system, and a pressure storage device,
- the at least one pressure chamber and the pressure storage device communicate with the pressurized medium system,
- a phase position between the driven element and the drive element is changeable by supplying pressurized medium to or discharging pressurized medium from the at least one pressure chamber by the pressurized medium system,
- the pressure storage device has a minimum fill pressure that is less than a pressure within the pressurized medium system at an idling rotational speed of the internal combustion engine.
