PURPOSE: To reduce the fluidity loss of sucking fluid when the discharging amount of the pump is in an increasing direction and the axial center of a cylinder block is inclined by a method wherein a partitioning wall for limiting the flow path of the sucking fluid is provided in the suction path of the fluid in a casing cover.
CONSTITUTION: The partitioning wall 23 for limiting the flow path of the sucking fluid is provided in the suction path 19 for the fluid, which is provided in the casing cover 15 forming a slide guidance surface 16. The location of the end of the partitioning wall 23 at the side opposing to the suction groove 11 provided on a slant plate 14 is determined so that the area of the flow path for the fluid limited by the partitioning wall 23, which is flowed from the suction path 19 into the suction groove 11, is minimized when the axial center 9 of the cylinder block is inclined to an angle in which the discharging quantity of the pump is maximized.
