Hydraulic Rotary orbital motor
These motors are used to generate torque and rotation. This type often resembles the pumps used previously in the drive system, quite the opposite. Where the original pump started the cyclic process to create pressure, the pressure in the engine pushes the cyclic process.
Gear motors can start any machine that uses gears to start the process. The high-pressure fluid flows along the gear, turning it and then into the drain hole. The second gear rotates to the first without direct contact with the working fluid. This type of engine is very simple and efficient.
Vane orbital motors operate with a pair of offset concentric cylinders. They work by filling the empty space with high pressure liquid, which leads to the fact that the outer cylinder becomes unbalanced and rotates. This sets the central cylinder in motion, removes spent fluid and allows fresh fluid to enter the chamber under pressure. Like the gearmotors presented above, they are low maintenance models that are more suitable for high speed applications.
Axial piston engines are the most common type. Cylinders are pressurized in the cycle to create an alternative piston movement, which is controlled by a gearbox with a given RPM. This model is highly adaptable and finds application in many different applications.
Linear hydraulic orbital motor
A hydraulic cylinder is used to deliver mechanical force in a linear stroke. The working fluid acts on the piston, providing a controlled stroke. They are often found in large mechanical systems, such as construction machines, and not in process equipment, such as pumps or transport systems. The science behind this installation allows the pressurized fluid to act over a large surface area, thus improving the force originally created by the hydraulic pump.
