摘要： A rotary valve having two, rotatable coaxial plugs in a casing with a piston slidable radially in the outer plug and connected by side links to the inner plug. The piston, which has the valve seating, is pivotally attached to the outer ends of the links by cam followers which are located in cam tracks having corner portions leading from a sealing surface in the casing fluid inlet and then curved portions extending round the axis of rotation of the plugs. Rotation of the inner plug from the closed position aligns fluid passages through the plugs with the casing inlet and outlet, by moving the cam followers down the corner portions of the cam tracks, to draw the piston away from the sealing surface after the links have snapped over top dead centre, and then along the curved portions, thus opening the valve.
摘要翻译：一种旋转阀，其具有两个可旋转的同轴塞，该壳体具有活塞，该活塞在外塞中径向滑动并通过侧连杆连接到内塞。具有阀座的活塞通过位于凸轮轨道中的凸轮从动件枢转地附接到链节的外端，凸轮轨道具有从壳体流体入口中的密封表面引导的角部，插头旋转。内塞从关闭位置的旋转通过使凸轮从动件沿着凸轮轨道的角部移动来将流体通道与套管入口和出口对齐，以在连杆松动后将活塞拉离密封表面然后沿着弯曲部分，从而打开阀门。

摘要： A rotary valve having a plug rotatably mounted in a casing by two shafts, one extending through each side of the casing, and a piston radially displaceable in a recess in the plug at a position circumferentially displaced from a fluid passage in the plug. Two links are pivotally attached at their inner ends to the shafts at an off-center position, and the other ends of the links are pivotally attached to the piston by cam track followers located in cam tracks on the casing. The cam tracks have corner portions leading from the sealing surface and then curved portions extending round the axis of rotation of the plug. Rotation of the shafts by a handle, from the valve closed position, draws the piston into the recess and away from a sealing surface around the casing fluid inlet, by the cam followers moving inwardly along the corner portions of the cam tracks, and then continuing along the curved portions to align the plug fluid passage with the casing inlet and outlet so that the valve is opened. The two links draw the piston into the recess by relative rotation between the shafts and the plug, and the plug is then aligned with the casing inlet and outlet by the shafts and plug rotating together.
摘要翻译：一种旋转阀，其具有通过两个轴可旋转地安装在壳体中的插头，一个延伸穿过壳体的每一侧的活塞，以及在塞子的凹部中沿着与插塞中的流体通道周向移位的位置可径向移位的活塞。两个连杆在其内端处以偏心位置枢转地附接到轴，并且链节的另一端通过位于壳体上的凸轮轨道中的凸轮轨道从动件枢转地附接到活塞。凸轮轨道具有从密封表面引出的拐角部分，然后围绕插塞的旋转轴线延伸的弯曲部分。通过手柄从阀关闭位置旋转轴，通过沿着凸轮轨道的角部向内移动的凸轮从动件将活塞吸入凹部并远离套管流体入口周围的密封表面，然后继续沿着弯曲部分将塞子流体通道与壳体入口和出口对准，使得阀门打开。两个连杆通过轴和塞子之间的相对旋转将活塞拉入凹槽中，然后将塞子与壳体进口和出口通过轴和塞旋转在一起。

摘要： There is provided a apparatus for the automatic compensation for deterioration or reduction in diameter of a cutting tool, such as a grinding wheel, whereby machining may be resumed, without further adjustment after such compensation. The invention is particularly suitable for remote operation under hazardous conditions such as might be experienced in highly radioactive environments.
