Flow diverter and operation of same

A diverter assembly for a shower tub arrangement that changes the distribution of water through two or more flow paths:

• a housing having an inlet for receiving fluid and first and second outlets for discharging fluid from the housing;
• an endless advancement structure positioned within the housing and comprising:
• a flow plate fixed to the housing and having a first opening in fluid communication with the first outlet in the housing and a second opening in fluid communication with the second outlet in the housing;
• a gearing arrangement rotatable relative to the flow plate, the gearing arrangement including a plurality of third openings in fluid communication with the inlet of the housing and a plurality of projections, each projection including a radially extending catch surface;
• and
• first and second pins positioned in the housing and biased into engagement with the gearing arrangement, engagement of the first pin with one of the catch surfaces placing the gearing arrangement in a first condition in which one of the third openings is aligned with the first opening in the flow plate, engagement of the second pin with one of the catch surfaces placing the gearing arrangement in a second condition in which one of the third openings is aligned with the second opening in the flow plate;
• and
• a handle coupled to the gearing arrangement for selectively rotating the gearing arrangement in a single direction relative to the flow plate to alternate between placing the gearing arrangement in the first condition and the second condition.
