Title:
フリーピストン式4ストロークエンジン
Document Type and Number:
Japanese Patent JP2009516801
Kind Code:
A
Abstract:
A free piston engine utilizes a shuttle frame external to combustion chambers to rigidly link shuttle parts reciprocating along a centerline. If the shuttle parts are spaced apart along the centerline, the shuttle frame may be struts extending from the shuttle parts and linked by rods. Alternatively the shuttle parts are within a tubular shuttle frame that forms part of the combustion chamber boundary. If one shuttle part is arranged around the other with both centered about the centerline, the shuttle frame may include an annular plate between a cylindrical inner shuttle part and an annular outer shuttle part. Alternatively the shuttle frame may include an inner tube with a cylindrical inner shuttle part within the inner tube, and an outer tube with an annular outer shuttle part arranged between the inner and the outer tubes so that the shuttle frame forms part of the combustion chamber boundary.
