Abstract

1425227 Rotary positive-displacement machines REGIE NATIONALE DES USINES RENAULT 6 Feb 1973 [8 Feb 1972] 5892/73 Heading F1F A rotary positive-displacement machine of the type having an N-lobed rotor d rotating in a planetary manner within an N + I-lobed stator c, such planetary motion being governed by KN- toothed pinion f fixed to an eccentric of the main shaft and being concentric with the eccentric so as to engage a K (N + I)-toothed g ring gear fixed to the stator and coaxial with the main shaft, comprises a pinion f 1 fixed to pinion f and indentical thereto, the pinion f 1 engaging a further ring gear g 1 which is not fixed but is eccentric with respect to said first ring gear g and is caused to execute a circular translatory motion by said pinion f 1 . The ring gear g 1 has a fluid distribution plate j non- rotatably attached thereto, the plate j having a pair of inlet and outlet ports k and m therein corresponding to each variable-volume chamber. Each chamber has a port q which thus periodically communicates with each of ports k and m as the plate k performs its circular motion. A particular construction using the above mechanism is also described Figs. 2 and 3 (not shown).
