摘要： In a hydraulic tensioner, an oil pressure control recess, at a proximal end of a cylindrical, plunger-receiving hole, receives from an oil supply, and also receives oil which oozes past a check valve and an inner sleeve inside the plunger, thereby returning the oil, which would leak to the outside in a conventional hydraulic tensioner, to the interior of the plunger.

摘要： In a tensioner for a timing belt or chain in an engine, a plunger, which is spring-biased in a protruding direction, is temporarily held in a retracted condition by a pivoted U-shaped or L-shaped wire spring. The spring has a locking portion engageable with a pin or groove on the plunger, and two arms having ends remote from the locking portion. The ends are pivoted to the housing on laterally displaced pivot axes. The lateral displacement of the pivot axes causes the wire spring to be under stress when its locking portion is engaged with the plunger, and the stress urges the locking portion toward a disengaged position. Thus, the plunger is held in its retracted condition during assembly by the locking portion of the wire spring, but is automatically released by disengagement of the locking portion from the plunger when the plunger is moved farther in the retracting direction.
摘要翻译：在用于发动机中的同步带或链条的张紧器中，沿突出方向弹簧偏置的柱塞通过枢转的U形或L形线弹簧暂时保持在缩回状态。弹簧具有可与柱塞上的销或凹槽接合的锁定部分，以及两个远离锁定部分的两个臂。端部在横向移位的枢轴上枢转到壳体。当其锁定部分与柱塞接合时，枢转轴的横向位移导致线弹簧处于应力之下，并且应力将锁定部分推向分离位置。因此，当弹簧的锁定部分组装时，柱塞被保持在其缩回状态，但是当柱塞在缩回方向上移动得更远时，柱塞通过将锁定部分从柱塞脱离而自动释放。

摘要： A fixed chain guide for absorbing vibrations during running of a chain is composed of a shoe in sliding contact with the chain and a plate base supporting the shoe. The plate base is secured to a mounting surface by two mounting seats integral with the base plate. The mounting seats are formed by bending them in opposite directions along bend lines, to have the seats in an essentially common plane but extending in opposite directions from the bottom edge of the base plate. The base plate is punched out of sheet stock in such a way that failure will not occur at the respective bend lines of the mounting seat by forming the ends of the bend lines so that there is a shear surface on the outside of the bend and a rupture surface on the inside of the bend. Punching the stock originally produces a shear surface adjacent one surface of the stock at the ends of one of the bend lines and a rupture surface adjacent the other side of the stock. The other of the bend lines is punched out at the ends by counterpunching from the opposite side of the plate base from the original punching to reverse the shear and rupture surfaces.
摘要翻译：用于在链条运行期间吸收振动的固定链条引导件由与链条滑动接触的鞋和支撑鞋的板底座组成。板基座通过与基板一体的两个安装座固定到安装表面。安装座通过沿着弯曲线沿相反方向弯曲而形成，以使座椅处于基本共同的平面中，但是从基板的底部边缘沿相反方向延伸。基板从片材冲压出，使得通过形成弯曲线的端部，使得在弯曲部的外侧上存在剪切面，并且在弯曲部的外侧具有剪切面，从而不会在安装座的各弯曲线处发生故障弯曲内侧的破裂表面。冲压坯料最初在一条弯曲线的端部附近的坯料的一个表面附近产生剪切表面，并且邻近该坯料的另一侧产生破裂表面。弯曲线的另一个在端部通过从基板的相对侧与原始冲压相反的方式被冲压，以反转剪切和破裂表面。

摘要： A shoe formed to relieve a sliding frictional resistance between a shoe for guiding the running of a transmission chain and the transmission chain, the cross-sectional shape of an incoming end and an outgoing end of a shoe (11) (11') for guiding a transmission chain is formed from a flat pressing-contact surface (12) for slidably guiding bottoms of all transmission chain plates. The flat surface extends longitudinally a short distance and transversely. The cross-sectional shape of an intermediate section between the incoming end and said outgoing end is formed with a convex pressing-contact surface (13A), (13B) for slidably guiding an bottom of less than all of the transmission chain plates, and has a transverse cross-section in which the pressing-contact surface or surfaces does not extend across the full width of the shoe to provide a recess for lubricant, and provide pressing-contact with less than all of the transmission chain plates.
