Abstract

An apparatus for transferring a fluid from a supply container to a desired receptacle. The apparatus includes a conduit having a fluid passage with a valve seat and a flexible containment member. A moveable sealing member is coupled to the flexible containment member and is configured for sealingly engaging the valve seat. An activator is coupled to the sealing member for displacing the sealing member from the valve seat to effect the creation of a reduced fluid pressure in the fluid in the supply container.

Claims

1. A combination of a supply container and a fluid transfer apparatus, the fluid transfer apparatus disposed in fluid communication disposition with the liquid in the supply container to thereby effect creation and communication of a reduced fluid pressure relative to a fluid pressure of the liquid in the supply container and thereby initiating flow of the liquid from the supply container, the fluid transfer apparatus comprising:

a) a frame;

b) a conduit coupled to the frame and defining a fluid passage, the fluid passage including an inlet, and outlet, and an orifice defined by a valve seat, and the conduit including a conduit section having a flexible containment member and defining a first fluid passage section comprising a space capable of changing its volume;

c) a moveable sealing member, coupled to the flexible containment member, and configured to sealingly engaging the valve seat; and

d) an actuator, pivotally coupled to the frame, and coupled to the sealing member to effect displacement of the sealing member relative to the valve seat in response to pivotal movement of the actuator relative to the frame;

wherein displacement of the sealing member from the valve seat by the actuator effects the creation and communication of the reduced fluid pressure to the liquid in the supply container.

2. The combination as claimed in claim 1, wherein the first fluid passage section is defined between a first valve means and a second valve means, each of the first and second valve means being disposed in the first fluid passage, wherein the first valve means is configured to prevent fluid flow from the space and to the inlet, and wherein the second valve means is configured to prevent fluid flow from the outlet to the space.

3. The combination as claimed in claim 2, wherein the first valve means is biased to seal fluid communication between the inlet and the space, and the second valve mans is biased to seal fluid communication between the space and outlet.

4. The combination as claimed in claim 3, wherein the first valve means is configured to open in response to a fluid pressure differential between the inlet and the space, wherein fluid pressure in the space is less than fluid pressure at the inlet, sufficient to overcome the bias of the first valve means to seal fluid communication between the inlet and the space.

5. The combination as claimed in claim 4, wherein the second valve means is configured to open in response to a fluid pressure differential between the space and the outlet, wherein fluid pressure in the space is greater than the fluid pressure at the outlet, sufficient to overcome the bias of the second valve means to seal fluid communication between the space and the outlet.

6. The combination as claimed in claim 5, wherein the displacement of the sealing member from the valve seat effects expansion of the space to thereby effect a reduced fluid pressure in the space sufficient to create the sufficient fluid pressure differential between the inlet and the space to overcome the bias of the first valve means to seal fluid communication between the inlet and the space.

7. The combination as claimed in claim 6, wherein the flexible containment member is a flexible diaphragm.

8. The combination as claimed in claim 7, wherein the sealing member is biased to sealingly engage the valve seat.

9. A fluid transfer apparatus configured for fluid communication disposition with liquid in a supply container to thereby effect creation and communication of a reduced fluid pressure relative to a fluid pressure of the liquid in the supply container and thereby indicating flow of the liquid from the supply container, the fluid transfer apparatus comprising:

wherein displacement of the sealing member from the valve seat by the actuator effects the creation and communication of the reduced fluid pressure to the liquid in the supply container.

10. The combination as claimed in claim 9, wherein the first fluid passage section is defined between a first valve means and a second valve means, each of the first and second valve means being disposed in the first fluid passage, wherein the first valve means is configured to prevent fluid flow from the space and to the inlet, and wherein the second valve means is configured to prevent fluid flow from the outlet to the space.

11. The combination as claimed in claim 10, wherein the first valve means is biased to seal fluid communication between the inlet and the space, and the second valve mans is biased to seal fluid communication between the space and outlet.

12. The combination as claimed in claim 11, wherein the first valve means is configured to open in response to a fluid pressure differential between the inlet and the space, wherein fluid pressure in the space is less than fluid pressure at the inlet, sufficient to overcome the bias of the first valve means to seal fluid communication between the inlet and the space.

13. The combination as claimed in claim 12, wherein the second valve means is configured to open in response to a fluid pressure differential between the space and the outlet, wherein fluid pressure in the space is greater than the fluid pressure at the outlet, sufficient to overcome the bias of the second valve means to seal fluid communication between the space and the outlet.
