ABSTRACT:
A water engine comprises a float arranged for reciprocal movement in a chamber under the action of a head of water. The chamber is filled with water from an upper level by means of a valve and is emptied to a lower level by means of a further valve. A cross-head is mounted atop the float and two pairs of hydraulic rams are pivotably connected to the crosshead. The pairs of rams are also pivotably connected to pairs of sliders which are adjustably mounted on stanchions. When the float is caused to rise, hydraulic fluid in the upper pair of rams is pressurized because of the shortening of the rams, while hydraulic fluid is drawn into the lower pair of rams by extension thereof. When the float is caused to fall, the opposite is true. Each pair of rams pivots as the float moves, the arrangement being such that for whichever pair of rams is on its working stroke there is progressively less shortening of that pair of rams per unit travel of the float.
