Reservoirs & Accessories

In motion control, it is often desirable — or necessary — to stop a moving load smoothly. A rubber bumper, a compression spring, or a dashpot all can accomplish this by absorbing energy. The bumper and spring store energy and release it after they are compressed, resulting in a rebound. A dashpot is a fluid-filled cylinder with an opening through which fluid may escape at a controlled flow. Any force acting against the piston in the cylinder encounters high resistance from the fluid at the beginning of the stroke, then much less as the piston retracts....More

Analogies exist between hydraulic flow and electrical flow, and the molecules of fluid in a hydraulic circuit behave much like the electrons in an electrical circuit. Let’s examine analogies between pressure and voltage and between ground and the hydraulic reservoir....More

Aluminized steel hydraulic oil reservoirs and fuel tanks for off-road and specialty vehicles used in agricultural, construction, and other utility equipment combine corrosion resistance of aluminum with structural strength (and lower cost) of steel....More

Desiccant filter breathers are being used more and more to trap moisture before it gets into a hydraulic reservoir. Although effective, they do not necessarily offer a permanent solution. That’s because the desiccant eventually becomes spent, and unless the desiccant or the entire unit is replaced, moisture will again be drawn into the reservoir....More
