Valve clearance compensation device and method for controlling a valve clearance compensating device for an internal combustion engine |
摘要 |
In a clearance compensating device for an internal combustion engine with an internal part movably arranged within a guide duct of an external part for adjusting a clearance of an associated valve of the internal combustion engine, a pressure chamber, and a storage chamber which is hydraulically connected to the pressure chamber for receiving hydraulic fluid are associated with the interior part. Between the two chambers a one-way valve is disposed for applying an actuating force to the interior part relative to the external part. A feeding device is hydraulically connected to a blocking chamber for supplying a hydraulic fluid to the blocking chamber in order to exert a blocking force to the internal part acting in a direction opposite the actuating force under the control of a timing device the blocking force being modified depending on a cycle of the timing devices.
