    摘要： A shock absorbing system has a nose assembly that is formed to inwardly collapse on impact and is guided by a sleeve that can slide with the nose as the nose collapses or can extend for a portion of the length of the nose while being held fixed. In the latter instance the nose can have a leading end that has a biasing member in a resilient material so that on impact some of the shock is taken up by compression of the biasing member with subsequent extension of the biasing member retracting the resilient covering so that it is less likely to bind in the surrounding tubular. The leading end of the sleeve or the resilient material encasing the biasing member also soften the blow to a closed ball when the tool is dropped so that the ball surface is less likely to mar.

    摘要翻译： 冲击吸收系统具有鼻部组件，其形成为在冲击时向内折叠，并且由套筒引导，套筒可随着鼻子塌陷而与鼻子滑动，或者可以在保持固定的状态下延伸一部分长度的鼻子。 在后一种情况下，鼻子可以具有前端，其具有弹性材料中的偏置构件，使得在冲击时，通过偏压构件的压缩来吸收一些冲击，随后偏置构件随后延伸缩回弹性覆盖物，使得 在周围的管中不太可能结合。 当工具下落时，套筒的前端或包围偏置构件的弹性材料也会使打击成为闭合的球，从而不太可能损坏球表面。

    摘要： The tool can run in and latch another tool such as a ball valve into a packer, for example. It has the capability of operating the valve while still engaged to the valve housing. Once the valve is operated and released a pressure test can be conducted while the tool is still engaged to the valve housing. After that a predetermined applied force allows release from the valve housing without the valve shifting mechanism still engaged. In a different configuration the tool can be a simple pulling tool to remove the valve housing without shifting it. The tool has a rotational lock to allow release from a packer by turning to the right. In another configuration it can be a latch tool for a production string that shifts the valve as it releases when the production string is pulled.

    摘要翻译： 例如，该工具可以进入并将诸如球阀的另一工具闩锁到封隔器中。 它具有在仍然接合到阀壳体的同时操作阀的能力。 一旦阀门被操作和释放，当工具仍然接合到阀壳体时，可以进行压力测试。 之后，预定的施加力允许从阀壳体释放，而阀移动机构仍然接合。 在不同的配置中，该工具可以是简单的拉动工具，以便在不移动阀壳的情况下移除阀门壳体。 该工具具有旋转锁定，以允许通过向右转动从封隔器释放。 在另一种配置中，它可以是用于生产线的锁定工具，其在拉制生产线时释放阀。

    摘要： A valving system includes, a tubular having a seat, and a body with a bore therethrough having a surface sealably engagable with the seat, the body being rotatable relative to the tubular between at least a first position, a second position and a third position, the first position occluding flow between an inside of the tubular and the bore the second position providing fluidic communication between the inside of the tubular and the bore via at least one cavity formed in the surface and a third position providing direct fluidic communication between the inside of the tubular and the bore
