Power Steering Cylinders with ports at only one end.

I was looking at the steering assist cylinders on my Ford 3000, I realized there are two hydraulic pressure lines to each cylinder, but they both are at the same end.
I assume the cylinders are double acting. So what sort of internal design layout magic allows this to work?
I am not that hydraulic cylinder aware, never took one like this apart. My other tractor's cylinder (an Allis) has a port at each end, which makes sense to me.
 
I've had that type cylinder apart, trim cylinders on IO marine outdrives.

It's a tube inside a tube. The oil flows between the inner and outer tube to get to the opposite end of the cylinder.
