I wish to restrict an internal door from opening into a kitchen unit. I

recessed on the door the other in the jam joined by a chain which
restricted the opening.

I think you'll find that that device is a closer rather than a
restricter. Mounted in the hinge jam the forces excerted by even
gentle pushing on the open edge of the door will be considerable.

Mechanical advantage between a push 32" away from the hinge and 1/2"
away is 64 times...

Door stops are best placed at the outer edge of the door. Block or
rubber stop on the floor is common or a door stop fixed to the
wall/skirting out of the way at high or low
level.
