摘要： An earth boring tool includes two coaxially-aligned, positive displacement motors. One motor turns a pilot bit and the other turns a reamer concentric with the pilot bit. The central bit bores the center of the hole and the reamer enlarges it. The central bit is rotated relatively faster, while rotation of the larger diameter reamer is relatively slow. The tool can thus be used to bore larger diameter holes without slowing drilling rates or adversely affecting performance of the cutter elements due to higher tangential velocities.
摘要翻译： 地面钻孔工具包括两个同轴对准的容积式电动机。 一个电机转动一个导向位，另一个电机转动一个与引导位置同心的扩孔器。 中心位钻孔的中心，扩孔器扩大。 中心钻头相对更快地旋转，而较大直径的铰刀的旋转相对较慢。 因此，由于较高的切向速度，该工具可用于钻孔较大直径的孔而不会降低钻孔速率或不利地影响刀具元件的性能。

摘要： A valve has a valve member (17) that is moveable along a first axis in a valve chamber ( ) between an open position and a closed position. In the open position the valve member is displaced from the valve seat such that a fluid inlet (pi) is connected to a fluid outlet (p2). In the closed position the valve member (17) is sealed against the valve seat so that the fluid path is closed. First (12) and second (46) opposed stacks of disc spring apply unequal loading resulting in a biasing force that biases the valve member towards the closed position. A first piston member (15) is movable in a first bore (14) relative to the valve member (17) and for moving the valve member in a first direction along the first axis. A second piston member (16) is movable in a second bore relative to the valve member (17) for moving the valve member along the first axis in a second direction opposite to the first direction. A first pressure compensation passage (71) extends between the fluid inlet (pi) and the first bore (14) such that the first piston member (15) is actuable by the fluid pressure in the fluid inlet (pi). A second pressure compensation passage (70) extends between the fluid outlet (p2) and the second bore such that the second piston member (16) is actuable by the fluid pressure in the fluid outlet. An actuator moves the valve member from the closed position to the open position.

摘要： A hydraulic coupling for sub sea applications comprises inter-engageable male and female connectors. The male connector defines a male member for receipt in a chamber defined by the female connector. Each connector has a respective check valve for controlling the flow of fluid through internal bores in the connectors. The check valves are actuable by an actuator between an open position in which hydraulic fluid may flow through the respective internal bore and a closed position in which such flow is interrupted, depending on the distance between the first and second check valves. The male and female connectors are moveable between an uncoupled position in which the check valves are in the closed position and a coupled position in which the male and female connectors are engaged and extend along a longitudinal axis with the male member occupying the chamber of the female connector in a sealed relationship. A pair of seals are provided one on the male member and the other on the in the chamber. The seals are arranged so that they seal the chamber at opposite ends by sealing against respective sealing surfaces in the coupled position. The distance between the first and second check valves in the sealing position is such that the actuator urges them to their open positions. The arrangement ensures that seawater between the connectors is allowed to escape before the sealing relationship is established and, upon coupling, the check valves are opened to allow fluid to flow.
