Definitions

  • Radial motors also called star motors, consist of pistons arranged to slide inside corresponding cylinders that are radially arranged around a central crankshaft.

Abstract

Le moteur radial (100) comprend une pluralité d'ensembles (A1, A2,... An) d'éléments radiaux (A11, A12,... Α1n; Α21, A22... A2n; Am1, Am2... Amn) reliés à un arbre de sortie commun (SA), et une pluralité de groupes (G1, G2, Gk) avec des ensembles (B11, B12,... B1j; B21, B22... B2j; Bi1, Bi2,... Bij) de cylindres (C) et de pistons (P) reliés à des arbres correspondants (SB1, SB2... SBi), ces ensembles (A1, A2,... An) d'éléments radiaux (A11, A12,... A1n; A21, A22... A2n; Am1, Am2... Amn) étant disposés par rapport aux ensembles de cylindres (C) et de pistons (P) précités, de manière que, en fonctionnement, une extrémité (EA) des éléments radiaux (A11, A12,... A1n; A21, A22... A2n; Am1, Am2... Amn) soit en contact séquentiel avec une extrémité (EP) du piston (P) d'un ensemble respectif des cylindres (C) et des pistons (P) entraînant ainsi la rotation de l'arbre de sortie commun (SA).
