Title (EN) MEDICAL AIR COMPRESSOR
(FR) COMPRESSEUR D'AIR MÉDICAL
Abstract:
(EN) A pump or compressor includes a rotating shaft, and at least a first piston rod substantially perpendicular to the rotating shaft and connecting a first pair of pistons at opposite ends of the piston rod. The piston rod moves back and forth relative to the rotating shaft. The compressor additionally includes a circular eccentric, and a circular ring connected to the circular eccentric via a bearing. A drive pin engages the circular ring at a fixed position on the circular ring and engages the at least a first piston rod. When rotational motion of the shaft rotates either the first piston rod and first pair of pistons or the circular eccentric, the drive pin and the first piston rod move back and forth relative to the rotating shaft.
(FR) L'invention concerne une pompe ou un compresseur comprenant un arbre rotatif, et au moins une première tige de piston sensiblement perpendiculaire à l'arbre rotatif et reliant une première paire de pistons à des extrémités opposées de la tige de piston. La tige de piston se déplace en va-et-vient par rapport à l'arbre rotatif. Le compresseur comprend en outre un excentrique circulaire, et un anneau circulaire relié à l'excentrique circulaire par l'intermédiaire d'un palier. Une broche d'entraînement vient en prise avec la bague circulaire à une position fixe sur la bague circulaire et vient en prise avec ladite première tige de piston. Lorsque le mouvement de rotation de l'arbre fait tourner la première tige de piston et la première paire de pistons ou l'excentrique circulaire, la broche d'entraînement et la première tige de piston se déplacent en va-et-vient par rapport à l'arbre rotatif.
