Is it Important to Know How Multicyl Works?
Not really. Our patented design is like a car engine, internally it is quite complicated but to the user it's very simple. You just put air in one end using a simple air valve and then you get hydraulic power out of the other end of the cylinder.
What is the Patented Principle?
Known as the 'flow-by' principle it allows the two stage pressure intensifier to self-adjust anywhere on the overall stroke. This means the cylinder will stall when it meets resistance greater than the force on the advance stroke.
What is the Benefit of a Two Stage, Self Adjusting Stroke?
For the user there are several benefits: simple air controls; lower air consumption as the power is only produced when you need it. Also there is no need to set the tooling to a precise height (as would be necessary in a mechanical press) as the hydraulic action simply "bottoms out" whenever the resistance is greater.
What Happens Inside the Cylinder During the 'Flow-By' Action?
The ram advances using the 'dashpot' principle until it meets resistance. Enstrapped oil begins to 'flow-by' the low pressure piston by means of precisely controlled clearances as the piston rod is allowed to continue.
