    Abstract: The viscous damper is formed with a body with a cylindrical wall presenting an edge with a circular tongue element thereon. A cap with a corresponding circular groove element is placed thereon so that the tongue and groove elements align with each other. The resulting tongue and groove configuration is ultrasonically welded thereby forming a hermetic seal. This particularly results in a very precise damper height which is important for small or miniature dampers.

    Abstract: The damper includes a piston assembly which travels within a cylindrical damper housing between an extended position and a retracted position. A transverse channel is formed proximate to the open end of the damper housing. A latching diamond travels within the transverse channel. The piston assembly includes a piston shaft with a camming wall sub-assembly formed thereon which engages the latching diamond so that the piston assembly is latched in a “push-push” configuration in the extended position. In this latched configuration, the latching diamond is detent engaged by a concave detent apex formed on an island which includes a longitudinally chamfered portion. Additionally, the flexibility of the island in which the concave detent apex is formed may be increased by transverse passageways or “cored-out” areas in the piston shaft immediately adjacent to the island. While the open latched configuration is normally released by incrementally extending and then releasing the piston assembly, it is possible that a user will attempt to release the open latched configuration by urging the piston assembly toward the retracted position. In this case, the island flexes and the latch diamond travels over a longitudinally chamfered portion of the concave detent apex free of damage to the island, the latch diamond, and other portions of the damper.

    Abstract translation: 阻尼器包括活塞组件，其在延伸位置和缩回位置之间的圆柱形阻尼器壳体内行进。 在阻尼器壳体的开口端附近形成横向通道。 锁定金刚石在横向通道内行进。 活塞组件包括活塞轴，其上形成有凸轮壁子组件，所述凸轮壁子组件形成在其上，与卡定金刚石接合，使得活塞组件在延伸位置中以“推 - 推”构型锁定。 在该锁定构造中，锁定金刚石由形成在包括纵向倒角部分的岛上的凹形棘爪顶端卡定。 此外，其中形成凹形棘爪顶点的岛的柔性可以通过紧邻岛的活塞轴中的横向通道或“芯出”区域增加。 虽然通常通过递增地延伸并释放活塞组件来释放打开的锁定配置，但是用户可能尝试通过将活塞组件推向缩回位置来释放打开的锁定配置。 在这种情况下，岛弯曲并且锁金刚石在凹形棘爪顶端的纵向倒角部分上行进，而不会损坏岛，锁金刚石和阻尼器的其它部分。
