Fluid transfer apparatus
First Claim
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.

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.

17. 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 initiate flow of the liquid from the supply container, 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, 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;

22. 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 initiate flow of the liquid from the supply container, 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 having an orifice axis, the conduit including a conduit section having a flexible containment member and defining a first fluid passage section comprising a space capable of change to its volume, the first fluid passage section including a first fluid passage subsection having an axis orthogonal to the orifice axis;
c) a moveable sealing member coupled to the flexible containment member, and configured for sealingly engaging the valve seat;
d) an actuator pivotally coupled to the frame, and configured 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 creation and communication of the reduced fluid pressure to the liquid in the supply container, and upon the displacement, the sealing member becomes disposed in the first fluid passage subsection. - View Dependent Claims (23)
