    • A swash plate piston (20) of integral, one piece design has outer surface portions in contact with much of the total available inner surface of the cylinder bore (18), but with a basically hollow design that can be easily manufactured. Outer (36) and inner (38) semi cylindrical segments of the piston (20) extend axially back from a cylindrical head (32), but leave the center of the piston body entirely open and empty. A slanted wing member (40) extends out and down from the inner segment (38), into the outer segment (36), creating a four sided, frame like structure of superior strength. All of the outboard outer surfaces of the piston (20) lie on the same cylindrical envelope as the cylinder bore (18) itself, giving good, even support. However, none of the outer surfaces, outboard or inboard, present any concavities that would jeopardize the ability to form the piston (20) with only two forming elements that part in a straight line.
    • 一体式设计的斜盘活塞(20)具有与气缸孔(18)的总可用内表面的大部分接触的外表面部分,但是具有可以容易地制造的基本上中空的设计。 活塞(20)的外部(36)和内部(38)半圆柱形部分从圆柱形头部(32)轴向延伸,但使活塞体的中心完全敞开和空。 倾斜翼构件(40)从内部段(38)向外延伸到外部段(36)中,形成具有优异强度的四边形框架结构。 活塞(20)的所有外侧外表面位于与气缸孔(18)本身相同的圆柱形外壳上,提供良好的均匀支撑。 然而,外侧或内侧的任何外表面都不会出现任何会损害只能形成直线的两个成形元件形成活塞(20)的能力的凹凸。
