Abstract
An internal combustion rotary volumetric motor operating on a four stroke cycle including a fixed exterior housing which delimits an annular space, a plurality of pistons that rotate in the same direction mounted in the annular space, a rod having a shaft integral therewith diametrically connecting the pistons in pairs and propelling the pistons by cyclical speed variation which causes a volume variation in the space delimited by radial surfaces of the pistons, the spaces between the pistons forming chambers of the motor operating on a four stroke cycle, a rotary crown having a plurality of ports formed therein, wherein the annular space within which the pistons move is delimited by the housing and the rotary crown having the ports through which the rods are engaged and which provide an angle of clearance for the rods for advancing and receding of the pistons, the rotary crown forming part of an outlet motor shaft, and a transmission mechanism attaching the rotary crown to the shafts.
