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. Conventional hydraulic cylinders are simulated in FLUENT. Singh, "Derivation of design requirements for optimization of a high performance hydrostatic actuation system," International Journal of Fluid Power, vol. Results show that the small outlet ports are the sources of energy loss in hydraulic cylinders. A new hydraulic system was proposed as a solution to relieve the hydraulic resistance in the actuators.
The hydraulic resisting forces, piston speed and mass flow rates are computed. Chenoweth, Aircraft flight control actuation system design vol.
Results show that the hydraulic resistance is significantly reduced in the proposed four ports actuators; and the proposed cylinders run faster than the conventional cylinders and a considerable amount of energyis saved as well.
