Document Type and Number:
WIPO Patent Application WO/2014/156547
Kind Code:
A1
Abstract:
An opposed-swash-plate-type liquid pressure rotary machine in which first and second pistons which project from both ends of a cylinder block move back and forth inside the cylinder and follow, respectively, first and second swash plates. The liquid pressure rotary machine is configured: so as to be equipped with a center spring for biasing the cylinder block toward the second swash plate; so that a storage hole (biasing-force receiving part) for receiving the biasing force of the center spring is formed in one end of the cylinder block, while the tip (counterforce receiving part) of a second neck part for receiving the counterforce from the second swash plate is formed at the other end of the cylinder block; and so that the center spring biases the cylinder block toward only the second swash plate.
