Abstract:
A valve apparatus for accurately controlling flow of fluids, comprising:a cap having an inner surface and an outer surface, a first cavity and a second cavity extending through said cap to allow fluid flow therebetween; an actuation means for receiving said cap thereon, and a void being defined through said actuation means; a diaphragm removably engaging said inner surface and being of sufficient size to occlude said first cavity and said cavity simultaneously, the diaphragm comprising a projection that biases against said inner surface of said cap and hermetically prohibits fluid flow between said first cavity and said second cavity; and a first member being maintained within said void of said actuation means, and said first member loosely interlocked with said diaphragm to allow said diaphragm to adjust while said first member forces said diaphragm against said inner surface as a result of a resilient means in a deactivated state and said actuation means withdrawing said diaphragm in an activated state, whereby control of fluid flow between said first cavity and said second cavity is achieved.
