In order to maintain high efficiency close, to isothermy despite high frequencies in a pneumo-hydraulic converter with reciprocating pistons, pipe cluster-heat exchange pipes (38) are provided in the gas working chambers of the converter and the exchange fluid in the pipes is kept at approximately ambient temperature. For this the gas working chambers must be arranged axially next to one another and, in order to eliminate dead space, connected in pairs by conical exchange valves (12a/12b) which take in the entire wall thickness of the valve flange (5a/5b) dividing the air chambers.

[ What is claimed is:] [11.] A pneumo-hydraulic converter which comprises:an housing which defines a first end portion, a middle portion and a second end portion,a first piston which is reciprocatingly movable in said middle portion to define two varying volume pre-pressure air chambers on opposite sides of said first piston,a second piston which is reciprocatingly movable in said first end portion to define a first hydraulic chamber and a first high-pressure air chamber on opposite sides of said second piston,a third piston which is reciprocatingly movable in said second end portion to define a second hydraulic chamber and a second high-pressure air chamber on opposite sides of said third piston,a rod which is connected to and extends between said second piston and said third piston and through said first piston, andheat exchanger means which extends through said first end portion of said housing, through said second piston, outside of said rod, through said third piston, and through said second end portion of said housing to convey cooling media through said housing.
