Abstract: A novel hydraulic pressure-boost system utilizing high-speed On-Off valves is studied in this paper. The hydraulic pressure-boost system is analogous to a boost converter in power ...

DFUA & DFUB – solenoid-operated directional poppet valves ... and manufacturer of high-performance screw-in hydraulic cartridge valves and manifolds that control force, speed, and motion as ...

The manifold allows for multiple valves to share single pressure and tank lines, simplifying connection to the whole hydraulic system. Although there are maintained directional valves, in which the ...

The EGR system works by returning a small portion of exhaust gas to the engine's combustion chambers through the intake manifold, lowering combustion temperatures and therefore reducing the amount of ...

Hart Energy’s Meritorious Awards for Engineering Innovation recognizes 17 technologies for engineering excellence in the upstream petroleum industry and highlights new products and technologies that ...

At the same time, soft coal is mined along soft sub layers using the main borehole, branch boreholes, and directional hydraulic jet to relieve the stress and improve the permeability of the coal seam.

The hydraulic manifold valve can be a complicated system, with internal passages overlapping and a convoluted inlet arrangement. With traditional manufacturing methods, holes are drilled into a solid ...
