    • An adjustable agitation system for an automatic washing machine includes a lost motion fluid drive connection between the input drive member and the agitator so that agitator oscillates through a lesser arc than the input drive member. The fluid drive is formed by pockets in the agitator skirt and corresponding paddles on the drive member skirt. The spacing of the drive member and agitator is varied to vary the differential between the drive member oscillation arc length and the agitator oscillation arc length. A connection member engages the input drive member and is selectively engageable with the agitator to connect the input drive member and agitator for conjoint oscillation.
    • 用于自动洗衣机的可调节搅拌系统包括输入驱动构件和搅拌器之间的空动流体驱动连接,使得搅拌器通过比输入驱动构件更小的电弧振荡。 流体驱动器由搅拌器裙部中的凹部和驱动构件裙部上的对应的桨形成。 改变驱动构件和搅拌器的间隔以改变驱动构件摆动弧长与搅拌器振荡弧长之间的差。 连接构件接合输入驱动构件并且可选择性地与搅拌器接合以连接输入驱动构件和搅拌器以进行共振。
