Hi.
Just want to be sure I actually have understood the difference between Alpha and Gamma. Please correct me if I'm wrong.
An Alpha has two working pistons, that means that both pistons seal to the cylinder walls at the full front area of the pistons. Even if there's a displacer fitted to the hot side piston, it's still an Alpha as long as the pressurized air is working towards the whole area of the piston on the hot side, and not only the piston rod on the hot side (then it would be a displacer of a Gamma, and not a working piston of a Alpha).
Both those are Alpha's, even thought the lower one has an displacer attached to the hot side piston?
