US Patent 11913688 Mechanical refrigeration system

Mechanical refrigeration system includes a compression device. The compression device has a pair of dual-action cylinders connected together by a movable rod thereof. A first cylinder acts as an element for compressing coolant fluid, for which purpose the rod is moved through the second cylinder, fed by a pressurised fluid that allows the flow of coolant fluid in the first cylinder and the flow of pressurised fluid of the second cylinder at the outlet of both devices to be constant, thus configuring a completely autonomous device that does not need electricity or any type of fuel.
