摘要： An autotensioner which is designed to apply appropriate tension to a timing belt of an engine or a belt that drives auxiliary machinery, for example, an alternator, compressor, etc. The autotensioner has an annular space that is partitioned into two chambers by a first partition wall which is provided on a fixed member and a second partition wall which is provided on a pivoting member, the annular space being filled with a viscous fluid. The first partition wall is formed with a passage which provides communication between the two chambers, and a check valve is provided in the passage. The check valve closes the passage when the tension in the belt increases suddenly, to resist the pivotal movement of the tensioner in one rotational direction, thereby enabling the tensioner to follow slowly and effectively the movement of the belt in which the tension is suddenly increased. The check valve opens the passage when the portion of the belt engaged by the tensioner becomes slack, thereby decreasing the resistance to movement of the second partition wall within the viscous fluid, thus enabling the tensioner to move rapidly in a rotational direction opposite the direction of movement of the tensioner when the tension in the belt increases.
摘要翻译： 一种自动张紧器，其被设计成对发动机的同步带或驱动辅助机械的带，例如交流发电机，压缩机等施加适当的张力。自动张紧器具有环形空间，其被第一分隔件分隔成两个室 壁设置在固定构件上，第二隔壁设置在枢转构件上，环形空间填充有粘性流体。 第一分隔壁形成有提供两个室之间的连通的通道，并且在通道中设置止回阀。 当带中的张力突然增加时，止回阀关闭通道，以抵抗张紧器在一个旋转方向上的枢转运动，从而使张紧器能够缓慢且有效地跟随张力突然增加的带的运动。 当由张紧器接合的皮带部分松弛时，单向阀打开通道，从而降低粘性流体中第二分隔壁的运动阻力，从而使张紧器能够沿与旋转方向相反的旋转方向快速移动 当皮带张力增加时张紧器的运动。
