A pump (100) utilizing a shape memory alloy member (50) which is connected to electric terminals (52) to be contracted by the supply of electric power for lowering a piston (40), the piston (40) mounted to slidably move within a cylinder (28) to thereby introduce a fluid into the cylinder (28) is raised by a biasing force of a bias spring (44) to externally discharge the fluid introduced in the cylinder (28). The pump (100) has a simple structure which is light and easily repaired and maintained.
Pompe (100) mettant en oeuvre un élément (50) constitué d'un alliage à mémoire de forme et relié à des bornes électriques (52) de manière qu'il se contracte sous l'action d'une alimentation électrique et que ceci provoque la descente d'un piston (40), le piston (40) est monté coulissant dans un cylindre (28) afin d'introduire un fluide dans le cylindre (28), ledit piston étant ramené à sa position haute par l'effort de sollicitation d'un ressort (44) afin d'évacuer vers l'extérieur le fluide introduit dans le cylindre (28). Ladite pompe (100) a une structure simplifiée, légère et facile à entretenir et à réparer.
