    Abstract: This invention relates to a hydraulic pig advance system comprising a control volume chamber (12) containing hydraulic fluid and a force transmitting member (16). The system further comprises two directional control valves (36, 40) which can be selectively repositioned to cause hydraulic fluid to cycle the force transmitting member (16) back and force such that in each cycle, a metered amount of hydraulic is transmitted into a pig housing (44) where it causes a pig (45) to move a predetermined distance.

    Abstract: [0049] A valve (10) and a hydraulic controller (45) are provider. The valve may combine a rotary-to-linear converter (24) with the hydraulic controller to provide for at least two mechanisms for actuating the valve. Additionally, the valve may include a mechanical lock mechanism (36) suitable for securing the valve at a desired flow position. The mechanical lock mechanism may also provide overload protection. That is, the mechanical lock mechanism may "slip" or disengage if torque forces reach undesired levels. The hydraulic controller may enable a "stepping" mode of control and "fast actuation" mode of control. The "stepping" mode may deliver a discrete quantity of a fluid, while the "fast actuation" mode may deliver a continuous quantity of the fluid.

    Abstract translation: 阀(10)和液压控制器(45)是供应商。 阀可以将旋转到线性转换器(24)与液压控制器组合以提供用于致动阀的至少两个机构。 另外,阀可以包括适于将阀固定在期望的流动位置的机械锁定机构(36)。 机械锁定机构还可以提供过载保护。 也就是说,如果扭矩力达到不期望的水平,机械锁定机构可能会“滑动”或脱开。 液压控制器可以实现“步进”控制模式和“快速启动”控制模式。 “步进”模式可以输送离散量的流体,而“快速致动”模式可输送连续量的流体。

    Abstract: A hydraulically operated fluid metering apparatus (54, 56) provides discharge of a known volume of fluid to an actuator (22) of a well tool. In one described embodiment, the fluid metering apparatus (54, 56) is connected to a hydraulic input of a well tool actuator (22). Discharge of the known volume of fluid to the actuator input causes a piston (42) of the actuator to displace a known distance, thereby producing a known increment of actuation of the well tool. The discharge of the known volume of fluid may be repeated to produce a desired total degree of actuation of the well tool.

    Abstract: An actuator for relatively moving two parts in a damped manner. The actuator includes a damper housing for connection to a first of the parts. The damper housing includes a damper chamber. The actuator includes a drivable damper rod for connection to a second of the parts and being movable relative to the damper housing. The damper rod includes a damper unit located within the damper chamber. The damper unit is relatively movable within the damper chamber with the damper unit movement corresponding to the relative movement between the damper housing and damper rod and the relative movement between the first and second parts. The damper unit is movable in response to hydraulic pressure force upon the damper unit. The actuator includes a pneumatic pressure source for providing a pneumatic pressure force that is transferred to provide the hydraulic pressure force upon the damper unit. The actuator includes a selectively actuatable blocking device for permitting transfer of the pneumatic pressure force from the pneumatic pressure source and blocking return of force to the pneumatic pressure source until the selectively actuatable blocking device is actuated.
