ABSTRACT:
An improved fluid energy translating device of the axial piston type includes a cylinder barrel mounted on a drive shaft. The cylinder barrel is rotatably coupled to the drive shaft through a splined connection which includes crowned male splines on the drive shaft and female splines within the cylinder barrel. A port plate having inlet and outlet passages abuts one end of the barrel and intimate contact therebetween is maintained by a plurality of disk or Belleville springs operably disposed between the drive shaft and the cylinder barrel.
