Abstract:
1. A linear guide device based on rolling-contact bearing technology for feeding working fluid to an assembly requiring working fluid, comprising; at least one fluid channel extending from a surface; a working fluid selected from the group consisting of lubricating grease and lubricating oil; and at least one screw element with a fluid port screwed from the surface into the at least one fluid channel for feeding working fluid into the fluid channel, the at least one fluid channel having a first section directly adjacent to the surface, a second section with a smaller diameter than that of said first section and, between the first section and the second section, having a first transition region with an annular surface, and the screw element having at least one sealing surface brought into sealing engagement with the annular surface, thereby forming a sealing effect without the use of additional sealing components, wherein material of the fluid channel surrounding the annular surface is deformed in the second section by a pressure applied by the screw element to the annular surface in the sense of reducing the volume of the fluid channel in the second section.
