<p><P>PROBLEM TO BE SOLVED: To downsize an accumulator by being able to get a hydraulic pressure ripple suppressing action by optimizing the layout of the accumulator, in a hydraulic pressure feeder for a driving force distributor which includes the accumulator for accumulating the oil pressure in a piston chamber. <P>SOLUTION: The piston chamber (32) is a chamber which is roughly circular in cross section viewed from the axial direction, being arranged around a rotating shaft (42), and in which the piston chamber (32) is provided with the first aperture (85), to which the first oil path (80) leading to an oil pump (75) is connected, and a second aperture (86), to which the second oil path (81) leading to the accumulator (83) is connected. The first aperture (85) and the second aperture (86) are arranged to be in positions where they are apart to its maximum within the cross section of the piston chamber (32) by being arranged on both sides each with the center (M) in the cross section of the piston chamber (32) between. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
