Air Over Oil Reservoir

A flow control valve in the oil line controls the cylinder advance speed.

Air over oil reservoir.

Rapid extend stroke to approach the work. The air over oil system uses compressed air introduced into the air oil tanks via a 5 2 air valve. The highest possible oil pressure available simply equals the air pressure supplied. 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.

Years of worry free inexpensive operation are virtually guaranteed because there are no moving parts. This lightweight compact unit is easily installed on any existing or new application. 12901 jim dhamer dr. 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. Air over oil reservoirs wall mount. 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. 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.

The sequence is as follows. Precision machining assembly.
