Device for separating drinking water fraction from sea water, has piston coupled to pushing-/traction element that is rotatably supported in eccentric, and valve control comprising control element that is movable by traction element

摘要

The device has a pump (1) pumping liquid under pressure into a separating device (3), where the pump includes a piston (5). The piston is coupled to a pushing-/traction element (9) that is rotatably supported in an eccentric (8), by movement of the piston over a shaft (11). The eccentric is rotatable by a drive shaft (4) of the pump. A valve control comprises a pressurization device for pressurization of the piston with a liquid fraction of the separating device, where the fraction is below residual pressure. The valve control comprises a control element that is movable by the element (9).
