Patent
CA 2213502
A reciprocal type of pump or motor structure wherein a piston (21) has a linear function actuated by a pair of coils (30, 31) energized alternately and in the pump structure a check valve (39) in an outlet of the structure which stretches to open said outlet under the impact of expelled fluids and of its own volition retracts to the closed position immediately upon the cessation of fluids being expelled.
L'invention concerne une structure de pompe ou de moteur à mouvement alternatif, dans laquelle un piston (21) effectue un mouvement linéaire commandé par une paire de bobines (30, 31) alimentées alternativement. Dans la structure de pompe, un clapet de non retour (39) situé dans une sortie de la structure s'allonge pour ouvrir ladite sortie consécutivement à l'impact des fluides expulsés et revient spontanément à la position fermée, dès que cesse l'expulsion des fluides.
