This video demonstrates the operation of multiple actuators developed by Mr. Strain, along with the operation of Mr. Reilley’s actuator patented in 1874. It provides visual demonstrations of the fluid flow through each design and explains the force accumulation principles of the 1874 invention, illustrating how the actuator develops its mechanical advantage.
