PISTONS
DESCRIPTION
There are several sizes and types of pistons used in an automatic transmission. Some pistons are used to apply
clutches. They all have in common the fact that they are round or circular in shape, located within a smooth walled
cylinder, which is closed at one end and converts fluid pressure into mechanical movement. The fluid pressure
exerted on the piston is contained within the system through the use of piston rings or seals.
OPERATION
The principal which makes this operation possible is known as Pascal's Law. Pascal's Law can be stated as: "Pres-
sure on a confined fluid is transmitted equally in all directions and acts with equal force on equal areas."
PRESSURE
Pressure is nothing more than force (lbs.) divided by
area (in or ft.), or force per unit area. Given a 100 lb.
block and an area of 100 sq. in. on the floor, the pres-
sure exerted by the block is: 100 lbs. 100 in or 1
pound per square inch, or PSI as it is commonly
referred to.
