description A piston pump includes: a first biasing mechanism configured to bias a swash plate in accordance with control pressure supplied; a second biasing mechanism configured to bias the swash plate against the first biasing mechanism; and a regulator configured to control the control pressure in accordance with self-pressure of the piston pump. The regulator has: an outer spring and an inner spring configured to be extended and compressed by following tilting of the swash plate; a control spool configured to be moved in accordance with biasing forces exerted by the outer spring and the inner spring, the control spool being configured to adjust the control pressure; an auxiliary spring configured to exert biasing force to the control spool against the biasing forces exerted by the outer spring and the inner spring; and an adjusting mechanism configured to adjust the biasing force exerted by the auxiliary spring.
