滑阀
Abstract:
与公知的滑阀相比不用增大板宽度，而通过扩大阀孔以及阀芯的截面积来扩大阀芯的轴部周围的截面积。阀孔(8)的截面形状为具有朝向壳体(7)的高度方向的长轴X和朝向宽度方向的短轴Y的细长形状，并具有：沿所述长轴X方向呈直线地延伸且相互平行的左右的孔侧壁(8a、8a)、将该左右的孔侧壁(8a、8a)的一端彼此连结的第一孔端壁(8b)、以及将所述左右的孔侧壁(8a、8a)的另一端彼此连结的第二孔端壁(8c)，阀芯(10)的台肩部(11‑13)的截面形状为具有朝向所述壳体(7)的高度方向的长轴X和朝向宽度方向的短轴Y的细长形状，并具有：沿所述长轴X方向呈直线地延伸且相互平行的左右的台肩侧壁(25a、25a)、将该左右的台肩侧壁(25a、25a)的一端彼此连结的第一台肩端壁(25b)、以及将所述左右的台肩侧壁的另一端彼此连结的第二台肩端壁(25c)。
Abstract(English):

The cross-sectional shape of a valve hole is an elongated shape having a long axis and a short axis, and has left and right hole side walls that are parallel to each other, a first hole end wall that connects one ends of the left and right hole side walls, and a second hole end wall that connects the other ends of the left and right hole side walls, and the cross-sectional shape of land portions of a spool is an elongated shape having a long axis and a short axis, and has left and right land side walls that are parallel to each other, a first land end wall that connects one ends of the left and right land side walls, and a second land end wall that connects the other ends of the left and right land side walls.
