Single Acting Cylinders:
In single acting cylinders the fluid is pressurized from only one side of the cylinder during both the expansion as well as the retraction process.
Double Acting Cylinders:
In the double acting cylinders, the pressure from the fluid is applied in both the directions.
Any double-acting cylinder may be used as a single-acting unit by draining the inactive end.

To keep the hydraulic fluid in (double acting cylinders) and to keep dirt/washwater/etc out.
single acting: actively driven by hydraulic fluid pressure in only one direction, passively returned in the other direction by another force (e.g. springs, gravity)double acting: actively driven hydraulic fluid pressure in both directions
Hydraulic and Pneumatic systems are similar in that they both use double/single acting cylinders to operate something - Be it an automatic door for pneumatics and other such trivial tasks, or JCBs with hydraulics. Another key similarity would be the way in which they work - they both take the easiest path where available and both use 3/2 valves. A major difference between them is the pressures involved, the output forces and the use of 4/3 (hydraulics) and 5/2 (pneumatics) to operate a double acting cylinder.
it runs without fluctuation i.r continuous flow......
Yes using the equals method. Example: Double a = new Double(Double.NaN); Double b = new Double(Double.NaN); if( a.equals(b) ) System.out.println("True"); else System.out.println("False"); If you execute the above code snippet you will see "True" in the console. If you try the "==" operator to compare the 2 values a and b you will get only false

Double-acting cylinders work similarly, but oil is pushed against one side of the cylinder, thus allowing a push or pull motion; these cylinders are used in construction machinery such as cranes and earth-moving machines.
By double skined pipes which has very low expansion factor.
Reciprocating pumps will deliver fluid at high pressure (High Delivery Head).They are 'Self-priming' - No need to fill the cylinders before starting.

If one takes a look at the schematic drawing of an auto-retract clamp and drill hydraulic circuit, one will see the single-acting clamp cylinder and quarter of an inch operator control valve. It also has double-acting work cylinder, as well as quarter inch air sequence valve.
No.
Use a small. 2x4 of piece of wood with welding vise grips
They compare it.
Reciprocating compressors are either single- or double-acting. In single-acting machines the compression takes place on only one side of the piston; double-acting machines use both sides of the cylinder for compression.
The working pressure acts from one side in single acting actuators while in double acting actuators strokes generating by each side.
