Abstract

In a radial, multi cylinder fluid pressure machine, adverse mechanical and/or fluid loads occurring during running are minimised by fluid pressure. The capacity of the machine is selectable by provision of a plunger sleeve and an inner plunger in each cylinder bore, and by valve means selectively controlling their operation so that they can work concurrently or the inner plunger works alone. The adverse loads are minimised by appropriate fluid pressure exerted at opposite ends of the working plungers.
