液压促动器锁定
摘要：
本说明书的主题尤其可体现为一种设备，它包括阀(100)，阀具有：阀壳体，其具有轴向膛孔；第一入口端口；第一出口端口；以及活塞(108)，其位于轴向膛孔内且具有第一流体通道，并且构造成允许活塞在轴向膛孔内在第一位置和第二位置之间进行往复轴向移动，在第一位置上，第一流体通道与第一入口端口和第一出口端口沿轴向对齐，以形成第一流体回路，在第二位置上，活塞阻塞第一入口端口和第一出口端口中的至少一个。设备还包括锁定组件，锁定组件可构造成在第一构造中将活塞固定到选定位置，以及在第二构造中不干涉活塞的往复轴向移动。
摘要（英）：

The subject matter of this specification can be embodied in, among other things, an apparatus that includes a valve with a valve housing having an axial bore, a first inlet port, a first outlet port, and a piston located within the axial bore and having a first fluid passage and configured to allow reciprocal axial movement of the piston within the axial bore between a first position in which the first fluid passage aligns axially with the first inlet port and the first outlet port to form a first fluidic circuit, and a second position in which the piston blocks at least one of the first inlet port and the first outlet port. The apparatus also includes a lockout assembly configurable to fix the piston into a selected position in a first configuration, and not interfere with reciprocal axial movement of the piston in a second configuration.
