International ClassB65B 1/04AbstractA fluid delivery device that may be used in any orientation is presented. The device includes a container, a first fluid in the container space, an inlet opening attached to a bladder, and an outlet opening. A second fluid enters the container through the inlet opening. The bladder, which receives the second fluid as it enters the container, expands with the amount of second fluid that is received. As more of the second fluid is received and the bladder expands, the first fluid is pushed out of the container through the outlet opening. The device may be used as a tire repair system, for example by coupling the inlet opening to an air compressor and coupling the outlet tube to a tire. The first fluid that's in the container space would be a sealant composition in this case. Different embodiments of the bladder are possible depending on the application.Field of SearchGas or variation of gaseous condition in receiverTire inflation Gas and other material separating passage or chamber FLUENT CHARGE IMPELLED OR FLUID CURRENT CONVEYED INTO RECEIVER Valve bag type WITH MEANS TO MOVE SUPPLY MEANS AND/OR RECEIVER TO, FROM OR DURING FLOW RELATION With baffle, spreader, displacer, drip ring, filter or screen With bag or liner securing means With inserted or external form for bag With casing or support WITH DISCHARGE ASSISTANT (E.G., IMPELLER, PUMP, CONVEYER, MOVABLE TRAP CHAMBER, ETC.)
