PLUNGER ENGINE Russian patent published in 1995 - IPC

FIELD: engine engineering. SUBSTANCE: engine has fixed unit 1 having cylinders 2 arranged over periphery, power shaft 4 set in radial bearings 5 and having inclined washers 9 with ring grooves on the faces. Rocking rings 11 received in the ring grooves and fixed against rotation with respect to unit 4 has ball supports and spherical locks of the bottom heads of the connecting rods coupled with pistons 3. One end of rocking jaws 12 is pivotally mounted inside the engine housing through pin 13 having a ball head. Two other ends of each jaw is pivotally connected with rocking pin 11 through a pair of cantilevers. Axes of pins 13 having ball head are perpendicular to axis of power shaft 4. Axes of cylindrical pins are positioned in the plane of inclined washer 9. The plane passes through the point of intersection of axes of inclined washer 9 and power shaft 4. Inclined washers 9 is provided with additional ball radial thrust bearings interposed between the inner surfaces of the rocking rings and surfaces of the ring grooves of the inclined washers. EFFECT: enhanced efficiency. 3 dwg
