Abstract
A radial engine includes an engine block (2) having a central aperture (14). A drive shaft (7) extends through the aperture and a planar cam plate (5,6) is fixedly mounted on the shaft. A pair of spaced opposed walls (25) extend from the surface of the plate. A reciprocatable piston (37) is slidably mounted within a cylinder (9). A cam follower is engaged with at least one of the walls (25), such that reciprocation of the piston (37) rotates the plate (5,6) and the shaft (7).
Claims11
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.
