摘要： A chemical injection system has a pump and an actuator connected to the pump. The actuator further comprises a first sensor for sensing a deactivated state of the pump; a second sensor for sensing an activated state of the pump; a computer connected to the first and second sensors and the actuator; and an interface connected to the computer, to receive commands from, and to transmit data to, a control point. The computer further comprises a stored program. The stored program contains instructions to energize the actuator to cause the pump to dispense a pre-determined quantity of chemical and to verify that the pump has actually operated to dispense the pre-determined quantity of chemical.

摘要： A fluid power unit has a cylinder in a housing, a piston slidable in the cylinder and dividing the cylinder into a retract side and an extend side, and a two-position control valve. The control valve has a spool and first and second pilots. The position of the spool is responsive to the first and second pilots. There is a retract poppet valve in the retract side of the cylinder, and an extend poppet valve in the extend side. The retract and extend poppet valves are biased to a closed position. The retract poppet valve is in a fluid path between the retract side and the control valve; the extend poppet valve is in a fluid path between the extend side and the control valve. The alternate movement of the piston in the cylinder alternately opens and closes the poppet valves, The circuit connects the poppet valves to the pilots and alternately applies and releases pressure to the pilots, causing the spool of the control valve to shift and apply inlet pressure to the piston on alternate sides. Thus the piston oscillates as long as inlet pressure is applied. All the fluid paths and the poppet valves are fluidly sealed inside the housing, so no gas is vented to the atmosphere.
摘要翻译：流体动力单元在壳体中具有气缸，可在气缸中滑动并将气缸分成回缩侧和延伸侧的活塞以及两位置控制阀。控制阀具有线轴和第一和第二导频。线轴的位置响应于第一和第二导频。在气缸的缩回侧有一个缩回提升阀，在延伸侧有一个伸出的提升阀。缩回和延伸提升阀被偏置到关闭位置。缩回提升阀处于缩回侧和控制阀之间的流体路径中; 延伸提升阀处于延伸侧和控制阀之间的流体路径中。活塞在气缸中的交替运动交替地打开和关闭提升阀。该回路将提升阀连接到飞行员，并交替地向飞行员施加和释放压力，使得控制阀的滑阀移动并将入口压力施加到活塞在交替的侧面。因此，只要施加入口压力，活塞就会振荡。所有流体路径和提升阀都被流体地密封在壳体内，因此没有气体排放到大气中。
