Working Principle and Process of Hydraulic CNG Compressor
The gas compression system uses a hydraulic cylinder to convert hydraulic energy into kinetic energy to drive the pistons. If the gas pressure in the cylinder is below the external pipeline pressure, compression continues. Once it exceeds the external pressure, gas is expelled via a one-way valve to external gas storage or a filling machine.

[Potential Energy to Kinetic Energy to Mechanical Energy to Electrical Energy] Initially, the valve is closed. But when the water reaches up to the max level that can create high pressure then we on the valves. The water with high pressure starts flowing and strikes to the turbine blades through the nozzle. The turbine blades start rotating.
A review of energy storage technologies in hydraulic wind turbines
With the maturity of hydraulic technology and the emergence of its advantages, such as stepless speed regulation, a large power-to-weight ratio and reusable energy [14], [15], [16], since 2009 some scholars have successively proposed the concept of hydraulic wind turbines, as shown in Fig. 1.The principle is to realize the transformation …

Hydraulic Accumulators
In hydraulic ERS, accumulators serve as hydraulic energy storage devices as well as shock absorbers and standby power sources. Fig. 15 shows the working principle of ERS using hydraulic storage. The biggest advantage when using a hydraulic accumulator is that it can easily be integrated and operated in the existing hydraulic circuit of HHEs.

Directional Control Valves Working Principle
A 3-position, 4-way valve stops an actuator or allows it to float. The 4-way function is a common type of directional control valve for both air and hydraulic circuits. A 3-position, 4-way valve is more common in hydraulic circuits. The 5-way valve is found most frequently in air circuits. A 5-way valve performs the same function as a 4-way valve.
