ventilanordning for governance of tillforseln of compressed air, water and / or other media to hand tools, foretredesvis tools for dentalarbete

摘要

The invention is a valve device for controlling the supply of compressed air, water and/or other media to at least one handheld tool (6-9), preferably dental tools. The valve device has a valve for each medium for each tool (6-9). In this invention, each valve has a first valve section (14) and a second valve section (15), both of which are influenced by an actuation body (11, 12) and can be moved in relation to each other between an open position and a closed position, as well as a hose (16) of flexible material connected to both valve sections (14, 15). When the valve sections (14, 15) are in the closed position, the hose (16) is bent between the valve sections so that it has a flow cut-off fold (30). When the valve sections (14, 15) are in the open position, the hose (16) is free of the flow cut-off fold.IMAGE
