Abstract

Improvements in the oil scraper rings for piston rods or similar elements, which comprise a main ring divided into two or more segments and suitable for seating in an annular mounting groove provided in the gland, the main ring of which has on its cylindrical surface At least two axially spaced annular retaining grooves each housing the outer base edge of a scraper ring blade whose opposite inner edge protrudes from the inner cylindrical surface of the main ring so that it constitutes an oil scraper edge applied to the stem when the main ring segments are subjected to a tension that pushes them against the stem, the annular scraper blades being divided according to the segmentation of the main ring and each blade segment being inserted with forced fit into the groove retention so that it is removable from it, when worn, p To replace it with a new scraper foil segment, characterized in that at least in a place located along each groove of retention of the main ring there is a projection that protrudes inside the groove between the adjacent ends of two segments of sheet so as to form a stop element that prevents the doctor blades from moving circumferentially in their respective grooves, the stop elements of the two retention grooves being circumferentially offset from each other so that they are axially misaligned with each other.
