Air Over Oil Reservoir

The highest possible oil pressure available simply equals the air pressure supplied.

Air over oil reservoir.

Figure 3 1 shows a single tank air over oil system with an air valve piped to an air over oil tank to power the rod end with its other port connected directly to the cylinder cap end. Several cylinder suppliers offer air oil tanks that consist of a cylinder tube with two cylinder end caps held on the tube with tie rods. Try a duramaster air over hydraulic tank today and see the difference. Rapid extend stroke to approach the work.

Years of worry free inexpensive operation are virtually guaranteed because there are no moving parts. Air over oil reservoirs wall mount. The air over oil system uses compressed air introduced into the air oil tanks via a 5 2 air valve. Automatic switch to controlled rate when resistance is met and pressure builds up to the point where a fabco air rv sequence valve actuates the 2 way shut off valve forcing fluidflow through the speed controlling needle valve.

The sequence is as follows. Single air oil tank used for 2 speed work stroke with shock control. Air over oil tanks do not intensify the oil pressure regardless of the tank s diameter or length. Ldi corporate click for map.

12901 jim dhamer dr. This lightweight compact unit is easily installed on any existing or new application. Precision machining assembly. The air from the valve is used to pressurize and drive the oil from each tank into the cylinder.

The cylinder s extend speed is very slow and controllable. A flow control valve in the oil line controls the cylinder advance speed.
