Apparatus for providing high- pressure fluid comprises a pair of cylinders 101, 101% feeding a common outlet 116, in which rams 102, 102% define chambers 103, 103% provided with non-return inlet valves 104, 104% and outlet valves 105, 105%. The cylinders are opposed on a common axis and the rams are moved by a common cam 110, the shape being such that one ram starts to compress just before the other reaches its extreme point. <IMAGE> |
