Title:
AXIAL PISTON PUMP OR MOTOR
Document Type and Number:
Japanese Patent JP3894463
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To surely prevent the proximal end of a piston from being separated out of a piston shoe while allowing them to slightly slide, relative to each other.
SOLUTION: A thread part 20A on the distal end side of a connection rod 20 is fastened in a through-hole 6C in a piston shoe 6, and a small diameter part 20C of the connecting rod 20 is extended through a through-hole 5C in the proximal end of a piston 5 so that a flange part 20B on the front end side of the connecting rod 20 is locked to an end plate 15 on the piston hollow part 5D side. Further, a predetermined gap is held between the outer periphery of the small diameter part 20C and the internal periphery of the through-hole 5C. Further, a fluid passage 20D is formed piercing through the connecting rod 20 on the center axis thereof.
