Fluid energy machine

Abstract

A fluid energy machine, comprising a crank drive (A) and a drive device which is mechanically connected to the crank drive, wherein the drive device has two electric motors, the respective output members of which are mechanically connected to the crank drive is disclosed. The fluid energy machine is arranged within a housing which seals the fluid energy machine with respect to the surroundings and which is connected to a pressure-holding system. A method for operating a fluid energy machine of this type is further disclosed.
