Abstract
This rotary swash plate hydraulic pump includes: a casing; a cylinder block that is disposed in the casing so as to prevent relative rotation of the cylinder block and including a plurality of cylinder bores; a plurality of pistons each of which is inserted into a corresponding one of the plurality of cylinder bores; and a rotary swash plate that is housed in the casing so as to be rotatable about an axis and reciprocates the plurality of pistons. The casing includes an inlet passage that is in the shape of a ring and to which each of the plurality of cylinder bores is connected. The inlet passage is formed on the other side of the cylinder block in an axial direction in the casing and positioned so as to overlap the plurality of cylinder bores.
