Title (EN) PUMP
(FR) POMPE
Abstract:
(EN) A pump comprises a housing (1) with a first fluid section (2), a second fluid section (3) and at least one third fluid section (4) separated by a reciprocating displacement assembly (5), wherein the reciprocating displacement assembly (5) comprises a first displacing element (6) and a second displacing element (7). The first displacing element (6) has a first pressure surface (8) in fluid contact with the first fluid section (2) and a second pressure surface (9) in fluid contact with the second fluid section (3). The second displacing element (7) is operatively connected to the first displacing element (6) and comprises at least one third pressure surface (10) in fluid contact with the at least one third fluid section (4). The first fluid section (2) comprises an inlet/outlet (11) for a drive fluid; the second fluid section (3) comprises an inlet/outlet (12) for a fluid; and the at least one third fluid section (4) comprises an inlet (13) and an outlet (14) for a liquid, each of the inlet (13) and the outlet (14) comprising a one-way valve (15, 16). The pump further comprises a valve assembly (23) for controlling the pressure of the drive fluid in the first fluid section (2) and the second fluid section (3).
(FR) Pompe comprenant un carter (1) doté d'une première section de fluide (2), d'une deuxième section de fluide (3) et d'au moins une troisième section de fluide (4) séparées par un ensemble à déplacement alternatif (5), l'ensemble à déplacement alternatif (5) comprenant un premier élément de déplacement (6) et un second élément de déplacement (7). Le premier élément de déplacement (6) comporte une première surface de pression (8) en contact fluidique avec la première section de fluide (2) et une deuxième surface de pression (9) en contact fluidique avec la seconde section de fluide (3). Le second élément de déplacement (7) est fonctionnellement relié au premier élément de déplacement (6) et comprend au moins une troisième surface de pression (10) en contact fluidique avec la ou les troisièmes sections de fluide (4). La première section de fluide (2) comprend une entrée/sortie (11) pour un fluide d'entraînement ; la deuxième section de fluide (3) comprend une entrée/sortie (12) pour un fluide ; et la ou les troisièmes sections de fluide (4) comprenant une entrée (13) et une sortie (14) pour un liquide, l'entrée (13) et la sortie (14) comprenant chacune un clapet unidirectionnel (15, 16). La pompe comprend en outre un ensemble clapet (23) pour commander la pression du fluide d'entraînement dans la première section de fluide (2) et la deuxième section de fluide (3).
