    • A phaser for maintaining an angular relationship between a crank shaft and a cam shaft or among more than one cam shafts is provided. The phaser includes a rotor having a plurality of vanes integral to the rotor and protruding from the rotor body. The plurality of vanes is disposed to oscillate within their respective chambers formed by the rotor and a housing, thereby maintaining the angular relationship. The phaser also includes a shoulder integral to the rotor and interposed between one of the pluralities of vanes and the rotor body, thereby ensuring that the rotor face is always covering a locking pin hole regardless of vane position. The phaser further includes an inlet check valve located within the phaser structure or in very close proximity to the phaser, thereby reducing control fluid leakage.
    • 提供了一种用于保持曲柄轴和凸轮轴之间或多于一个凸轮轴之间的角度关系的相位器。 移相器包括具有与转子成一体并从转子本体突出的多个叶片的转子。 多个叶片设置成在其由转子和壳体形成的各自的腔室内振荡,从而保持角度关系。 移相器还包括与转子成一体并且插入在多个叶片中的一个叶片和转子体之间的肩部,从而确保转子面总是覆盖锁定销孔而与叶片位置无关。 移相器还包括位于相位器结构内或非常接近移相器的入口止回阀,从而减少控制流体泄漏。
