ABSTRACT:
A fluid operable power unit which is particularly adapted for movement of a compaction head in a refuse container. However, the power unit is also useful in other types of mechanism.
The power unit comprises a plurality of telescopically movable cylinders and pistons. Fluid pressure is applied for movement of the first cylinder. Then increased fluid pressure is applied for movement of the second cylinder. As the first cylinder ceases to move, fluid pressure increases and automatically operable valve means traps the fluid which has moved the first cylinder. Then increased fluid pressure moves the second piston and second cylinder. As the second piston and the second cylinder move under the influence of increased fluid pressure, the fluid which is trapped is increased in pressure.
Thus, high pressure forces act to move an actuator member for compaction or for any other purpose.
