Abstract:
PCT No. PCT/NL92/00212 Sec. 371 Date May 18, 1994 Sec. 102(e) Date May 18, 1994 PCT Filed Nov. 19, 1992 PCT Pub. No. WO93/10345 PCT Pub. Date May 27, 1993.A free-piston engine having a fluid pressure unit, comprises a cylinder and a piston arranged therein. The piston is equipped with a plunger-shaped extension including a working section having a room bordered by a first axial face of the plunger-shaped extension and the volume of which is reduced when the piston makes an expansion stroke, and to which a discharge channel to a high pressure accumulator and a supply channel from a supply reservoir connects. The piston further includes a compression section including a chamber having a first chamber portion enclosed by a second axial face in the bottom dead center of the piston and a second chamber portion bordered by a third axial face. The first chamber section decreases at the start of the compression stroke of the piston, wherein the first chamber portion has an open connection with a compression accumulator through a first connecting channel and the second chamber portion unit is connected to the compression pressure accumulator through a second connecting channel and is connectable to a pressure device for starting the compression stroke, whereafter the first connecting channel is opened in order to exert pressure on the third axial face. The plunger-shaped extension includes a passage extending from the first to the second chamber portion in the bottom dead center of the piston. A resiliently supported and axially movable closure element extends within the second chamber portion that lies in the path of the passage in the third axial face and encloses the passage at the end of the expansion stroke of the piston and opens it at the start of the compression stroke.
