    摘要： A hydraulic device in an internal combustion engine for adjusting a rotation angle of a camshaft in relation to a crankshaft includes a tubular stator and a rotor connected in fixed rotative engagement with the camshaft and having plural vanes in spaced apart relationship to define pressure chambers on both sides of the vanes. The stator is connected in fixed rotative engagement with a crankshaft-drive timing pulley and constructed to define with the rotor vanes the pressure chambers. The stator is made by a shaping process without material to effect a mass reduction. Pressure medium is supplied to or purged from the pressure chambers to selectively adjust the position of the rotor in relation to the stator and thereby the position of the camshaft in relation to the crankshaft.

    摘要翻译： 用于调节凸轮轴相对于曲轴的旋转角度的内燃机中的液压装置包括管状定子和与凸轮轴固定旋转接合的转子，并且具有间隔关系的多个叶片，以在两者上限定压力室 叶片的两侧。 定子以固定的旋转接合与曲轴驱动正时滑轮连接，构造成与转子叶片限定压力室。 定子由成型工艺制成，没有材料可以实现质量减少。 压力介质被供应到压力室或从压力室清除，以选择性地调节转子相对于定子的位置，从而相对于曲轴调节凸轮轴的位置。

    摘要： A hydraulic device in an internal combustion engine for adjusting a rotation angle of a camshaft in relation to a crankshaft includes a tubular stator and a rotor connected in fixed rotative engagement with the camshaft and having plural vanes in spaced apart relationship to define pressure chambers on both sides of the vanes. The stator is connected in fixed rotative engagement with a crankshaft-drive timing pulley and formed in single-piece construction with an end wall to thereby exhibit a pot-shaped structure. The pot is made without material removal from a sheet metal part and constructed to define with the rotor vanes the pressure chambers. Pressure medium is supplied to or purged from the pressure chambers to selectively adjust the position of the rotor in relation to the stator and thereby the position of the camshaft in relation to the crankshaft.
