Question Spring Newbie

Nice to meet you.
I was just wondering if there are compression springs that have less resistance when being compressed and bound back with a strong repulsive force?
I’m sorry for the question that seems to ignore the laws of physics.

Answer Tokai Spring

Thank you for posting your question, Spring Newbie!!!

It is said that the compression coil spring reduces the resistance (compression force) during compression and strengthens the repulsive force during the compression force is released, but this cannot be achieved by using the compression coil spring alone. I think that there are cases where that kind of operation is possible by adding an auxiliary function to the compression operation using hydraulic pressure or compressed air.
