Circuit symbol for a double-acting cylinder with end position cushioning (adjustable)
End position cushioning is a way of decelerating the piston of a cylinder and thus avoiding damage to the piston or the end positions of the chambers due to rapid impact of the piston.
This is achieved by adding damping pistons with a smaller cross section in the end positions.
Working principle
Here, kinetic energy is converted into thermal energy. With constant deceleration, the law of conservation of energy applies :
