Abstract
An axial piston pump of the swash-plate variety having a rotating cylinder block and pistons movable in a longitudinal direction within bores formed in the block, and having a reversing capacitance for reducing pressure pulsations. For the further reduction of such pulsations, one or more channels, each having an associated discharge opening, are formed into a web of the valve plate of the pump to sequentially couple the reversing capacitance into fluid communication with the cylinder bores passing across the web.
