BELLOWS PUMP-COMPRESSOR Russian patent published in 2024 - IPC F04B19/06 F03B13/18 

FIELD: pump-compressor design.

SUBSTANCE: bellows pump-compressor comprises suction and discharge valves 10-13, a working chamber 1 formed by interconnected bellows elements 2 closed on one side by a movable wall 3, and on the other side by a fixed bottom 4. The elements 2 are equipped with stiffening rings 5 to prevent deformation of the elements 2 under the hydrostatic water pressure at the installation depth of the chamber 1. A cylinder 6 is attached to the bottom 4 inside the chamber 1, which is the piston of the air compressor. A water pump plunger 7 is attached to the cylinder 6, which is included in the water pump housing 8. The housing 8 is attached to the wall 3. The wall 3 comprises a seal for the plunger 7. Valves 10, 11 are located on the movable wall of the working chamber. The valves 12, 13 are located on the housing 8. The housing 8 is connected to a buoy with positive buoyancy, which drives a bellows pump-compressor.

EFFECT: possibility of simultaneous generation of pneumatic and hydraulic energy.
