ABSTRACT:
An internal combustion engine comprising an engine block including a plurality of parallel, spaced apart cylinder modules, each module having a cylinder bore and a pair of pistons in each bore which are simultaneously movable in opposite directions and a rotatable shaft parallel to the cylinder modules. A wobbler member connected to and rotatable with the shaft means, has a pair of end portions connected by a central portion, each end portion having a centerline forming an angle with the rotatable shaft and wobbler end portion. A pair of bearing members are provided within each spider assembly and located at opposite ends of each wobbler end portion, each having a general frustro-conical annular shape with relieved areas in its outer surface to provide reduced bearing contact areas and bearing friction. A connecting rod for each piston is fixed at its outer end to the spider assembly and is connected at its inner end to a piston so as to provide both rotational as well as linear side movement of the connecting rod inner end within the piston. A lubrication system supplies liquid lubricant under pressure to both the bearings and the inner ends of said pistons.
