摘要： An apparatus (50) for pumping a fluid from a fluid reservoir (30), the apparatus (50) comprising a piston (13, 14) adapted for reciprocating upwardly and downwardly for pumping the fluid. The apparatus (50) further comprises a first annular fluid chamber (32) partially delimited by the piston (13, 14), a second annular fluid chamber (34) laterally surrounding the first fluid chamber (32), and a fluid communication recess (6) adapted for providing a fluid communication between the first fluid chamber (32) and the second fluid chamber (34). A movable valve (5, 15, 19) is provided which is adapted so that when the flow of fluid originating from the fluid reservoir (30) to the first annular fluid chamber (32) is disabled by the movable valve (5, 15, 19), the piston (13, 14) moves upwardly and fluid flows from the second fluid chamber (34) into the first fluid chamber (32), and when the flow of fluid originating from the fluid reservoir (30) to the first annular fluid chamber (32) is enabled by the movable valve (5, 15, 19), the piston (13, 14) moves downwardly and fluid flows from the first fluid chamber (32) into the second fluid chamber (34).

摘要： The invention relates to a pumping system (3) for pumping fluid. The pumping system (3) comprises a first pumping unit (1) comprising a first flow path (4) and a second pumping unit (2) comprising a second flow path (5). The fluid pumped by the first pumping unit (4) is guided through the first flow path (4), and the fluid pumped by the second pumping unit (2) is guided through the second flow path (5). The first pumping unit (1) and the second pumping unit (2) are functionally coupled. The first flow path (4) and the second flow path (5) are adapted to be functionally independent from each other.

摘要： The present invention describes a pumping device (1) for pumping fluids. The pumping device (1) comprises a force transmitting element (2), a tension unit (3) coupled to the force transmitting element (2) and a seal element (10). The force transmitting element (2) is adapted for transferring an upstroke and a downstroke to a pump plunger (5) for pumping fluid (12). The tension unit (3) is adapted for applying a tension force (F) to the force transmitting element (2) for keeping the force transmitting element (2) under tension during the upstroke and the downstroke. The seal element (10) is adapted for sealingly preventing pumping fluids (12) during the downstroke and for enabling pumping fluid (12) during the upstroke. A part (16) of the seal element (10) is rigidly coupled with the force transmitting element (2).
