Improvement to machine sliding shoe devices, in particular hydraulic pumps and motors.

摘要

P The sliding shoe device comprises a first element, such as a shoe (10), provided with a bearing surface (11), a second element, such as a slide or plate (2), provided of a mating surface (3), means suitable for introducing a hydraulic fluid under pressure into at least one pocket (12) formed in the bearing surface (11) of said first element (10) to keep the two surfaces apart l 'from each other by escaping from the pocket by the clearance thus established between said two surfaces, said pocket (12) having an active surface greater than that of the surface of said face (8) subjected to the pressure of use of hydraulic fluid, tending to push the first element towards the second. /P
