Abstract:
A fluid flow control apparatus for controlling and delivering fluid at a continuously variable flow rate, the apparatus comprising:a. a fluid-tight housing; b. a valve tube body housed within said fluid-tight housing and extending the length of said fluid-tight housing and out at both ends of said fluid-tight housing; c. a female hose connector integrally formed at one end of said valve tube body for connecting to a fluid supply source; d. an elongated flexible hose having an outflow end and the other end coupled to the other end of said valve tube body and in-fluid communication with said female hose connector; e. a rotatable ball valve installed within said valve tube body and having a rotating shaft extending out from a sidewall of said valve tube body and operationally connected to an electric reversible motor through a coupling member so as to be thereby rotated to continuously and incrementally varying the fluid flow rate through said flexible hose; f. an activating switch located at said outflow end of said flexible hose and electrically coupled to said reversible motor, the switch having a forward direction button and a reverse direction button for controlling the direction of said motor; and g. means for supplying power to said reversible motor; h. whereby said ball valve is rotatable for continuously varying the fluid flow rate through said flexible hose.
