  • FIGS. 11A and 1 IB the conduits 129 of the flow regulation device 110 are shown with greater detail. More specifically, the conduits 129 and the cylindrical housings 160 are secured together with complementary threaded portions 190a, 190b.
  • the conduits 129 include two conduits 129a, 129b having one of the outlet openings 124a, 124b, and one conduit 129c having the inlet opening 118.
  • Each of these conduits 129a, 129b, 129c includes a male threaded extensions 190a which is received in a female threaded aperture 190b in the cylindrical housings 160.
  • the present flow regulation device 10, 110 a user does not need to bend over at the spigot to start and stop water. Rather, a mere push of a pedal with the user’s foot will start/stop the water flow. Additionally, by providing multiple outlets, each having an independent control, the flow regulation device 10, 110 allows for multiple hoses to be selectively provided with water and controlled independently for each other. Finally, by using a design that can be controlled with a user’s foot, the device 10, 110 can be placed in an easy-to-reach place and may be operated with minimal effort providing for a more enjoyable gardening experience.

Abstract

Un dispositif de régulation de débit d'eau comprend un corps ayant une ouverture d'entrée et au moins une ouverture de sortie. Chaque ouverture de sortie est associée à un dispositif d'actionnement qui commande l'écoulement d'eau hors de l'ouverture de sortie associée. Une pédale ou un capuchon peut être enfoncée par un utilisateur afin de commander sélectivement le flux d'eau vers l'une des sorties.
