Abstract (en)

[origin: WO9711729A1] A fluid flow rate control device comprises a first vented fluid chamber (60) having an upper fluid inlet end with a hollow spike (46). A free floating float valve (70) in the first chamber blocks the flow of fluid into the first chamber from a fluid container (12) providing a constant pressure head. A lower end of the chamber is connected, through a flow regulator (66), to an upper inlet end of a second, vented, drip chamber (62), the lower end of which is adapted for connection to a discharge tube. A second, free floating float valve (140) in the second chamber blocks the flow of fluid from the second chamber into the discharge tube when the fluid level in the second chamber is at or below a preestablished minimum level and blocks flow of fluid into the second chamber when the level in the second chamber reaches a preestablished level.
