Abstract (en)
[origin: WO9512730A1] A pool cleaner having an improved self-starting vibratory power source including a power-source chamber (24a) laterally defined by a pair of sealing walls (30f), a vibrator (30) which pivots in the chamber and has two wall-facing edges (30w) adjacent to the sealing walls and a pair of upstream flow-facing edges (30ue) positioned to be alternately reactive to fluid dynamic forces, and a seal (30d) along each wall-facing edge (30w) in sealing relationship with the sealing wall (30f) adjacent thereto and freely movable with respect to the sealing wall to accommodate passage of dirt and debris. Preferred embodiments include seals that have upstream arcuate surfaces (30us) which by virtue of wide notches (30i) in the vibrator, are substantially free of contact with the vibrator, and back edges (30h) substantially exposed to flow upstream of the vibrator, such that the seal is freely driven against the sealing wall by pressure differentials, freely self-adjusts to allow passage of dirt, and prevents accumulation of dirt.
