Abstract

The engine is of the type having a cylinder block (1) with radial pistons (7), rotatable on a ported shaft (4), and a piston guide (11, 13, 14) imparting a reciprocating motion to the pistons and rotating eccentrically relative to the cylinder block on bearings (17) on either side of the ported shaft. The bearing surfaces of the two bearings (17) have the same diameter (D1) this diameter being greater than the diameter (Ds) of the ported shaft (4). The difference in diameters is preferably at least equal to twice the eccentricity (E). The bearing surface of at least one of the bearings (17) may be formed on a ring (17) with eccentric bore fitted on a common shaft (4).
