Palmberg, "Separate controls of meter-in and meter-out orifices in mobile hydraulic systems," SAE transactions, vol.
The small sized outlet ports of the cylinders resist the flow of discharged oil; and as a result the piston motion is slowed down.
This causes a lot of heat generation and energy loss within the actuators.
The study investigates and analyzes the possibilities of reducing the hydraulic resistance and increasing efficiency of the hydraulic actuator.
A new hydraulic system was proposed as a solution to relieve the hydraulic resistance in the actuators.
The proposed system is a four ports hydraulic cylinder fitted with a novel flow control valve. Goldenberg, "Design of a new high performance electrohydraulic actuator," in Proceedings of The International Conference on Advanced Intelligent Mechatronics, IEEE/ASME,, 1999, pp.
And as far as we know, it has been forming in the earth’s upper atmosphere since the atmosphere was made back on Day Two of Creation Week (part of the expanse, or firmament, described in Genesis 1:6–8). Cosmic rays from outer space are continually bombarding the upper atmosphere of the earth, producing fast-moving neutrons (subatomic particles carrying no electric charge) (Figure 1a).1 These fast-moving neutrons collide with atoms of nitrogen-14, the most abundant element in the upper atmosphere, converting them into radiocarbon (carbon-14) atoms.
