摘要： A variable-camshaft-timing mechanism is provided with a conically spiral spring valve as a check valve. When the conically spiral spring valve is opened, a plurality of flow passage clearances are formed between adjacent windings of the check valve, whereby a pressure loss of the working fluid can be reduced when passing through the check valve. When a reverse flow is generated, the check valve receives the reverse flow in its axial direction. Thus, the reverse flow of the working fluid can be utilized as a thrust force in a close direction of the check valve. A valve closing responsiveness of the check valve can be improved.
摘要翻译：可变凸轮轴正时机构设有锥形螺旋弹簧阀作为止回阀。当锥形螺旋弹簧阀打开时，在止回阀的相邻绕组之间形成多个流动通道间隙，由此当通过止回阀时可以减小工作流体的压力损失。当产生逆流时，止回阀在其轴向方向上接收逆流。因此，工作流体的逆流可以用作止回阀的紧密方向上的推力。可以提高止回阀的关闭阀的关闭性。
