Air Over Oil Hydraulic Systems

Air pressure pushes down on the hydraulic fluid the fluid is not compressable so the pressure energy is transfered to the hydraulic fluid.

Air over oil hydraulic systems.

As the name suggests this type of braking system is a combination of parts of an air brake system and a hydraulic brake system. A typical air over hydraulic brake system a t automatic transmission and m t manual transmission location of one type of load proportioning valve. Coupling low pressure hydraulic cylinders with air over oil tanks is a common way to create an air over oil system. These tanks hold more than enough oil to stroke the cylinder one way.

This is a very simple and cost effective way of producing a soft acting hydraulic system. Flow controls in the lines to the cylinder from the oil tanks not shown on drawing will meter the oil as it exits each cylinder port. Coupling low pressure hydraulic cylinders with air over oil tanks is another common way to create an air over oil system. It uses both air and hydraulic compression to operate the brakes.

This allows you to do without a hydraulic pump and the other mechanisms needed to pressurize hyd fluid. Having an air valve piped to the air over oil tanks forces oil from the tanks into the cylinder. Adding the control rigidity and power of hydraulics to a pneumatic machine adding the control rigidity and power of hydraulics to a pneumatic machine control with air oil tanks air oil tanks provide a nice alternative to hydraulic systems when precise cylinder motion is required. The tox pressotechnik air to oil cylinders also known as the tox powerpackage are energy saving pneumatic operated air hydraulic cylinders that feature an integrated oil system and automatically activated power strokes.

They cost less and take up far less space. The air over oil system uses compressed air introduced into the air oil tanks via a 5 2 air valve. Having an air valve connected to the air over oil tanks forces oil from the tanks into the cylinder. We supply equipment to the automotive appliance electronic medical industries and more.
