Document Type and Number:
Japanese Patent JP2012082747
Kind Code:
A
Abstract:
To provide a swash plate type piston pump-motor for simplifying a structure.
A piston pump is provided for expanding and contracting a volume chamber by a piston, by reciprocating the piston in response to rotation of a cylinder block by slidingly contacting with a swash plate 40 via a shoe, and includes the disk-like swash plate 40 and a swash plate storage part for fitting this swash plate 40.
