The Power Products intensifier cylinder is a reliable but simple idea. Using compressed air at shop pressure you are abel to generate very large forces with short cycle times.

1. (Fast approach) Air is applied to port 1, causing your tooling to close the work piece.

2. (Power Stroke) Air is applied to Port 2, forcing the plunger rod into the oil boosting its pressure.

3. (Return) Air is applied to Port 3A and 3.
