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.
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.

Years of worry free inexpensive operation are virtually guaranteed because there are no moving parts.
The highest possible oil pressure available simply equals the air pressure supplied.
A flow control valve in the oil line controls the cylinder advance speed.
Air over oil reservoirs wall mount.
Air over oil reservoirs provide precision hydraulic power from shop air.
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.
Air over oil tanks do not intensify the oil pressure regardless of the tank s diameter or length.
The sequence is as follows.
