Document Type and Number:
Japanese Patent JP6280783
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To extend the life of a connection part between a shaft and a cylinder block in a water pressure rotary machine.SOLUTION: An axial passage 13 which communicates with a supply passage 8 or a discharge passage 9 and a radial passage 14 are provided in a shaft 1. Water serving as a working fluid is drawn from the supply passage 8 or the discharge passage 9 into the axial passage 13 by a centrifugal force caused by rotations of the shaft 1. The water passes through the shaft 1 to be discharged from an outer periphery of the shaft 1 through the radial passage 14. The water that is discharged from the radial passage 14 by the centrifugal force of the shaft 1 passes through a case 3 to be circulated to the supply side through a circulation passage 16.
