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.

Air over oil reservoir.

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. This lightweight compact unit is easily installed on any existing or new application. Rapid extend stroke to approach the work. Air over oil reservoirs provide precision hydraulic power from shop air.

Single air oil tank used for 2 speed work stroke with shock control. Years of worry free inexpensive operation are virtually guaranteed because there are no moving parts. Try a duramaster air over hydraulic tank today and see the difference. A flow control valve in the oil line controls the cylinder advance speed.

Precision machining assembly. 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 air from the valve is used to pressurize and drive the oil from each tank into the cylinder. 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.

The cylinder s extend speed is very slow and controllable. The sequence is as follows.
