Abstract (en)

[origin: EP2246128A2] The method involves completely flooding each of conduits with fluid, where fluid pressure acting on the fluid in the conduits generates flow of the fluid in the conduits. The conduits are flooded, and negative pressure is applied on the fluid in the conduits. A reversing valve (8a) is located between a set of fluid lines (3) and a vacuum container (6) in a collecting duct (5). Another reversing valve (8b) is located between the vacuum container and a collection container (10) in a return line (9). An independent claim is also included for a device for removing production remnants from conduits in workpieces.
