Abstract

1,102, 027. Rotary-piston internal combustion engines. REGIE NATIONALE DES USINES RENAULT. April 1, 1965 [April 4, 1964], No. 13951/65. Heading F1F. To cool the piston of a rotary-piston I. C. engine having a four-lobed piston planetarily rotatable within a casing having five working chambers such that two oppositely disposed piston lobes 2, 4 are always subjected to hot working and the other two lobes 3, 5 to cold working, the piston comprises an outer perpheral lobe defining wall connected by end walls (23), (24), Fig. 2 (not shown) to a tubular hub 18, oppositely disposed hollow radial arms 6, 7 connecting the hub to the hot lobes 2, 4 radial partitions 10, 11 between the hub and the cold lobes 3, 5 and intermediate transverse webs 19, 20, 21, 22 interconnecting the end walls. Liquid coolant flows outwardly through the arms 6, 7, to the hot lobes spreads in both directions without any established circulation towards the cold lobes and returns to the hub through outlet openings 15, 16, 17, 18.
