Abstract: A servo regulator that causes a servo piston to move on the basis of working fluid pressure in two pressure chambers includes: a sleeve that is inserted into an insertion hole formed in a case and has a supply port capable of supplying a working fluid from a fluid pressure source to one of the pressure chambers; a spool valve disposed in the sleeve so as to be biased by a biasing member; and a solenoid that is attached to the case in order to drive the spool valve via a plunger. The sleeve includes a pressure receiving portion on which a fluid pressure of the working fluid from the fluid pressure source is exerted, and is pressed against an end surface of the solenoid by a biasing force acting on the pressure receiving portion.

Abstract: An opposed swash plate type fluid pressure rotating machine in which a first piston and a second piston projecting from opposite ends of a cylinder block reciprocate in a cylinder, respectively following a first swash plate and a second swash plate includes a center spring for biasing the cylinder block toward the second swash plate. A housing hole (biasing force receiving part) for receiving a biasing force of the center spring is formed on one end part of the cylinder block. The tip of a second neck (reaction force receiving part) for receiving a reaction force from the second swash plate is formed on the other end part of the cylinder block. The cylinder block is biased only toward the second swash plate by the center spring.
