IMPACT™ Cycle Of Operation
1. Starting Point
The IMPACT™ full cycle of operation is illustrated below on a single-piston spring return
actuator. In the initial startup the spring chamber and the centre chamber are not pressurized.
Supply line
2. “ON" command to the actuator
At the ON command air pressure from the supply line is applied through the IMPACT™ and
into the centre chamber of the actuator causing the piston to retract and compress the spring.
The centre chamber stays pressurized until the OFF command is given.

3. “OFF" command to the actuator
At the OFF command air pressure is directed from the centre chamber to the spring chamber
as the spring pushes the piston back. The air pressure in the spring chamber and the centre
chamber reach equilibrium.
Pressure
equilibrium
4. Spring End Position
As equilibrium is reached, the air in the centre chamber is released through the supply line it
contributes additional force to the spring closing motion. Pressurized air is trapped until the
next ON command.

5. Next “ON" command
At the next ON command air pressure from the supply line is applied through the IMPACT™
and into the centre chamber and at the same time exhausting the trapped air from the spring
chamber.
