Abstract (en)
[origin: EP0011145A1] 1. A slide shoe for hydrostatic piston machines on the slide sole (13) of which are formed hydrostatic and hydrodynamic pressure fields serving for relieving, wherein the central hydrostatic pressure field is influenced through a bore (17) formed in the slide shoe (1) and in communication with the high pressure side and is bounded by a first annular groove (18, 30, 32, 34) surrounding it, and comprising a second annular groove (19, 31, 35) of greater diameter extending concentrically with respect to the first annular groove and which issues at the side edge of the slide sole (13), characterized in that, both annular grooves - as is known - have a triangular cross-section and that the said cross-section is made so asymmetrical that the outer flank (19'') of the annular groove (19, 31, 35) with the larger diameter and the inner flank (18'') of the annular groove (18, 30 ; 32, 34) with the smaller diameter forms a shallow angle with the slide sole whereas the two other flanks (18', 19') extend parallel to the axis of the shaft (2) of the slide shoe.
