    摘要： A coupler for coupling an attachment to an excavator or other machine comprises a powered actuator for actuating a locking member into and out of said locking state, a first power coupling unit, and a second actuator for moving the power coupling unit into and out of an engaging position in which it is engagable with a corresponding second power coupling unit of the attachment. The coupler is configured to cause the first power coupling unit to move into the engaging position after said latching member adopts the locking state and, when decoupling the attachment from the coupler, to cause said latching member to remain in its locking state until after the first power coupling unit is moved out of its engaging position.

    摘要： In the exemplary embodiments a shuttle (100) slides across a valve (20), which forms a coupling (10), from an open position to a closed position. In the open position, the shuttle (100) is arranged to allow fluid to pass through the valve. In the closed position the shuttle (100) is arranged to close the valve (1). The shuttle (100) carries a tablet (140) that is biased to move relative to the shuttle (100) to seal against a sealing surface and thereby plug the valve closed. In a one-way valve application, fluid pressure acts upon the side of the tablet to assist in urging the tablet against the sealing surface. Alternatively, surge protection can be provided by biasing the tablet to move towards the sealing surface against the fluid pressure. Combining two valves to form the coupling (10), the coupling can be arranged to be separated with the two valves closed. The coupling can include a first bleed valve that accesses the space between the two sealing surfaces so that the space can be bled after closing the valves. The two valves are coupled together by a clamping mechanism to form the coupling. The clamping mechanism can be manually released, as in a block and bleed application, or arranged to automatically release under a predetermined load, as in a marine breakout application. Advantageously, the same base platform can be used in both applications.
