Title (EN) MICRO PUMP COMPRISING AN INLET CONTROL MEMBER FOR ITS SELF-PRIMING
(FR) MICROPOMPE COMPRENANT UN ORGANE DE CONTROLE D'ENTREE PERMETTANT SON AUTO-AMORCAGE
Abstract: front page image
(EN) The invention concerns a micro pump (10; 100) comprising at least a first plate (12), and a second plate (20), an intermediate plate (18), a pumping chamber (24) and inlet and outlet control members (28, 30). The invention is characterised in that said inlet control member (28) is a non-return valve located on the greater part of said intermediate plate (18) thickness, consisting of a mobile member (40) and a part in the form of a membrane (42) located in the proximity of one of the plates (12, 20), linking said mobile member (40) to said intermediate plate (18) remainder and enabling, by its elasticity, the movement of said valve (28) between a closed position and an open position, said mobile member (40) being traversed by an orifice of limited volume.
(FR) L'invention concerne une micropompe (10; 100) comprenant au moins une première plaquette (12), une deuxième plaquette (20), une plaque intermédiaire (18), une chambre de pompage (24) et des organes de contrôle d'entrée et de sortie (28, 30). Selon l'invention, ledit organe de contrôle d'entrée (28) est une valve anti-retour située sur la majeure partie de l'épaisseur de ladite plaquette intermédiaire (18), composée d'un organe mobile (40) et d'une partie en forme de membrane (42) située à proximité de l'une des plaquettes (12, 20), reliant ledit organe mobile (40) au reste de ladite plaquette intermédiaire (18) et permettant, par son élasticité, le mouvement de ladite valve (28) entre une position fermée et une position ouverte, ledit organe mobile (40) étant traversé par un orifice de volume limité.
