The highest possible oil pressure available simply equals the air pressure supplied.
Air over oil tanks do not intensify the oil pressure regardless of the tank s diameter or length.
Precision machining assembly.
Years of worry free inexpensive operation are virtually guaranteed because there are no moving parts.
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.
A flow control valve in the oil line controls the cylinder advance speed.
Try a duramaster air over hydraulic tank today and see the difference.
The cylinder s extend speed is very slow and controllable.
The air over oil system uses compressed air introduced into the air oil tanks via a 5 2 air valve.
Rapid extend stroke to approach the work.
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.
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.
