Title:
LIQUID PUMP SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/079409
Kind Code:
A1
Abstract:
A liquid pump system is achieved that can obtain a large amount of potential energy with a small amount of kinetic energy. This liquid pump system (1) comprises: a first chamber (2) an internal space (2a) of which forms at least a portion of an airtight space, the first chamber (2) containing a gas inside the internal space (2a); a first pressurizing bag (3) that is disposed in the internal space (2a) of the first chamber (2), and that deforms accompanying a change in the gas pressure inside the internal space (2a) of the first chamber (2) and suctions or discharges a liquid; and a gas pressure changing unit (4) for changing the gas pressure of the internal space (2a) of the first chamber (2). When the gas pressure of the internal space (2a) of the first chamber (2) is changed and the first pressurizing bag (3) suctions the liquid or discharges the liquid from the first pressurizing bag (3), dynamic lift is generated on the liquid inside the first pressurizing bag (3) due to the deformation of the first pressurizing bag (3).
