Title (EN) HYDROIMPEDANCE PUMP
(FR) POMPE A HYDRO-IMPEDANCE
Abstract:
(EN) A hydro-elastic pumping system (20) formed from an elastic tube element (21) having attached end members (23, 25) with different hydroimpedance properties, wherein the elastic element is pinched (26) with certain frequency and duty cycle to form asymmetric forces that pump fluid
(FR) L'invention concerne un système de pompage (20) hydro-élastique formé à partir d'un élément tubulaire (21) élastique auquel des éléments d'extrémité (23, 25) possédant des propriétés d'hydro-impédance différentes sont fixés. Ledit élément élastique est pincé (26) à une certaine fréquence et selon un certain cycle de travail afin de former des forces asymétriques permettant de pomper un fluide.
