Patent FR-2313560-A1 (FR)
Title: Engine with external fuel combustion - drives turbine through hydraulic coupling within same casing
Inventor: SARRAUD PHILIPPE
IPC: F01C7/00
Filed: 1974-10-01
Abstract: The engine has a cylindrical casing within which a turbine is mounted off centre. Because of the eccentricity there is an annular passage part of the way round the cylinder casing and this is separated from the turbine by a dividing wall forming a sector of a circle. An external combustion chamber on the side of the cylinder casing communicates with the cylinder through a port at one end of the partly circular annular passage. The turbine casing is partially filled with water. Suitable gaseous fuels are introduced into the combustion chamber and the expansion resulting from the combustion forces the gases through the annular passage. They then can exert a pressure on the water which impinges on the turbine to produce rotation.
