Hydraulic Cylinder

Hydraulic cylinders get their power from pressurized hydraulic fluid, which is typically oil. The hydraulic cylinder consists of a cylinder barrel, In which a piston connected to a piston rod moves back and forth. The barrel is closed on each end by the cylinder bottom (also called the cap end) and by the cylinder head where the piston rod comes out of the cylinder. The piston has sliding rings and seals. The piston inside of the cylinder in two chamber (rod end). The hydraulic pressure acts on the piston to do linear work and motion.

Flange trunnions and/or clevisses are mounted to the cylinder body. The piston rod also has mounting attachment to connect the cylinder to the object or machine component that it is pushing.

A hydraulic cylinder is the actuator or “motor” side of this system. The generator side of the hydraulic system is the hydraulic pump which brings in a fixed or regulated flow of oil to the bottom side of the hydraulic cylinder, to move the piston rod upwards. The piston pushes the oil and the other chamber backto the reservoir. If we assume that the oil pressure in the piston rod chamber is approximately zero, the force of the piston rod equal the pressure in the cylinder times the piston area (F=PA)

The piston moves instead downwards if oil is pump into the piston rod side chamber and oil from the piston area flows back to the reservoir without pressure The pressure in the piston rod area chamber is ( pull Force) / (piston area / piston rod area)
