Patent AT-E400739-T1: [Translated] SADDLE BEARING BUSH FOR AN AXIAL PISTON PUMP
Description
A saddle bearing liner ( 30 ) for a variable displacement axial piston pump ( 10 ) includes two axially-spaced apart bearing surfaces ( 62, 64 ) with an offset central section ( 54 ) integrally joining them. A hollow projection ( 80 ) extends radially from the convex side of the pressure bearing section ( 50 ) and is received with a recess ( 82 ) of the housing ( 12 ) to locate the liner ( 30 ). The liner ( 30 ) has radially extending ledges ( 70, 72 ) which mate with surfaces ( 74, 76 ) of the housing ( 12 ) to inhibit skewing of the bearing liner ( 30 ) relative to the axis of the bearing surfaces ( 62, 64 ). The projection ( 80 ) is hollow and opens to the bearing surface ( 62 ) so that presurrized fluid from the housing ( 12 ) can be injected between the bearing surface ( 62 ) and the mating surface ( 22 ) of the swashblock ( 20 ). The projection ( 80 ) also prevents the liner ( 30 ) from rotating about the bearing surface axis.
