<p>A swash plate hydraulic device for use as a swash plate hydraulic pump and a hydraulic motor, comprising a plurality of block plates (41-45) divided at split planes orthogonal to a cylinder block axis (X) and brazed to one another to constitute a cylinder block (4), the inlet side block plates (41, 42, 44, 45) near plunger swash plates (9a, 19a) formed with inlet holes (25i, 39i) which bear plungers (27, 41) slidably, and the remaining block plates (43-45; 41-43) on the back side formed with backside holes (25o, 39o) which are larger in diameter than the inlet holes (25i, 39i) and define an oil chamber which outer peripheral surfaces of the plungers (27, 41) face. Accordingly, there is provided a structure of a cylinder block which is excellent in mass production feature.</p> |
