Abstract
A valve assembly having a cap defining a first and second fluid flow passage for allowing the flow of fluid is attached to a seat member which is coupled to an actuator. A plunger having an adjustably attached diaphragm is maintained within the seat member and the actuator, and the plunger positions the diaphragm over the first and second fluid flow passage. The actuator controls the plunger and determines the retraction of the plunger to allow fluid flow and the insertion of the plunger to prevent fluid flow.
Claims23
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.

A valve assembly for controlling fluid flow, 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, and a wall on said inner surface separating said first cavity and said second cavity;
- a diaphragm removably biasing against said wall and said inner surface and being of sufficient size to occlude said first cavity and said second cavity simultaneously when biased against said inner surface and said wall, the diaphragm comprising a first projection adapted to removably engage said wall on said cap and hermetically prohibit fluid flow between said first cavity and said second cavity;
- a first component having a seat portion and an actuation portion and a void being axially defined therethrough, said seat portion being adapted to receive said cap thereon to maintain said diaphragm therebetween;
- and
- a first member being maintained within said void in a movable manner and said first member loosely interlocks with said diaphragm on a side distal to said cap to allow said diaphragm to adjust while said first member forces said diaphragm against said inner surface and said wall as a result of a resilient means in a deactivated state and an actuation means withdrawing said diaphragm in an activated state to control fluid flow.

A valve assembly for controlling fluid flow, 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, and a wall on said inner surface being defined between said first cavity and said second cavity to separate same;
- a substantially oval diaphragm having a minor axis and a major axis a projection along said minor axis, and said diaphragm being of sufficient size to occlude said first cavity and said second cavity simultaneously when biased against said inner surface and when said projection is biased against said wall;
- a first component having a seat portion and an actuation portion and a void being axially defined therethrough, said seat portion being adapted to receive said cap thereon to maintain said diaphragm therebetween;
- a first member being maintained within said void in a movable manner and said first member engaging said diaphragm in a pivoting manner on a side distal to said cap, and said first member forcing said diaphragm against said inner surface and said wall as a result of a resilient means to prevent fluid flow in a deactivated state;
- and
- an actuation means being located on said actuation portion in order to cause said first member to disengage said diaphragm from said inner surface and said wall to allow fluid flow in an active state.
