The valves in the valve assembly are activated buy the pendulum when the well is deviated from the vertical. Deviation from vertical as low as 0.2ºare enough to activate the valve.

V-Pilot Components 组成部件
The V-Pilot has two sections. The upper section is a modified GeoForce Motor. The lower section is the vertical drilling device. V-Pilot 由两部分组成，上部是改良的GeoForce马达，下部是垂直钻井部分 The two parts are delivered separately to the rig site and are easily connected before going in the hole. 两部分分开运输到井场， 下钻时直接连接
The lower section is a hydro-mechanic device.
下部是液压机械设备 The most important parts are: 重要部件包括： Pendulum 大钟摆总成 Valve assembly 阀门总成 Pads. 垫片总成

当产生井斜时，大钟摆系统激活阀门总成的阀门，产生侧 向力，使钻具重新回到垂直状态。最小井斜0.2º 时可以激活
阀门。

When one (or two) valve is opened by the pendulum, it allows the hydraulic fluid to actuate one (or two) of the 4 pistons in the opposite side.
How it Works 工作原理
The GeoForce motor is powered by the drilling fluid and it’s
shaft rotation is transferred to the shaft in the lower section.
GeoForce马达通过泥浆驱动将动力传递到下部的垂直钻 井设备部分 The shaft rotation powers up the hydraulic pumps.
