| 摘要 |
A hydrostatic machine with a cylinder block ( 6 ), within which sleeve holes ( 28 b) are arranged, in which sleeves ( 28 ) sit, surrounding piston bores ( 28 a) in which pistons ( 29 ) are mounted, such as to be displaced back and forth and the pistons ( 29 ) extend into the cylinder block ( 5 ) such as to define cylinders ( 26 ) with the front ends thereof. According to the invention, the risk of piston seizure can be reduced, whereby the sleeves ( 28 ) comprise an axially-defined recess ( 41 ) in the outer surface thereof, in the region facing away from the cylinder and the region with the greatest piston radial force, pressing the pistons ( 29 ) against the wall of the piston bore.
