DEVICE FOR THE RELATIVE VARIATION OF THE TURNED POSITION OF A TREE IN RELATION TO A DRIVE WHEEL.

摘要

Device for the relative variation of the rotated position of a shaft (1) in relation to the drive wheel (5), especially a camshaft of a combustion engine, with a variation device (3) with two chambers of pressure, which act against each other, with a pump (16) of pressurized medium, with a reservoir (17) of pressurized medium and with at least one control valve (13), in which one of the chambers pressure is connected, during the variation process, with the medium pressure pump (16) and the other pressure chamber is connected with the pressure tank (17), characterized in that at the beginning of the variation process, one of the Pressure chambers are connected to the medium pressure pump (16), before the other is connected to the pressure medium tank (17).
