Abstract

Improvements in sealing devices, for a gap that extends between two areas of unequal high pressure between two coaxial cylindrical elements that reciprocate one with respect to the other with a predetermined stroke length such as the piston and the housing of the pump of a fuel pump for an internal combustión engine and with a barrier fluid supplied to the gap, characterized in that two circumferential channels are provided in said elements that are coaxial with the elements, with a distance between their adjacent edges that is equal to or greater than the stroke length, and because a pressure barrier fluid supply source is connected to the channel located closest to the lowest pressure zone, while a cavity or sump with a pressure lower than the pressure of the source of barrier fluid, is connected to the channel located closest to the area where the pressure it is higher.
