Abstract:
1. A radial engine including: an engine block having a central aperture; a drive shaft extending through said aperture; a spaced pair of cam plates rotationally fixed with respect to each other, the plates being fixedly mounted on said shaft; each cam plate including a planar face, the planar face of one cam plate opposing the planar face of the other cam plate; the opposing faces each including a pair of spaced opposing walls defining a substantially “figure 8” shaped continuous loop, the walls on one said face being aligned with the walls on the opposing face; at least one cylinder fixed with respect to said block and extending outwardly from said block; a reciprocatable piston slidably mounted within said cylinder; a connecting rod fixedly connected at one end to said piston and having an opposing free end; a slider bearing located on said free end of said connecting rod, said slider bearing engaging with a guide for guiding said slider bearing during reciprocation of said piston; and a cam follower engaged with said walls of each cam plate, wherein reciprocation of said piston rotates said plates and said drive shaft; and wherein said guide is defined by a radially extending bore in said engine block and sidewalls of said bore laterally support said slider bearing during reciprocation of said piston.
