Abstract (en)
The engine has two crankshafts installed in a housing (8) holding lubricant. The crankshafts are arranged so that an end of each crankshaft sealingly projects from the housing (8) to prevent escape of lubricant into a housing (1) in which a piston reciprocates. The piston rods are arranged in the housing (1) outside the housing holding lubricant.
