Claim 3

The apparatus as recited in claim 1 wherein a small diameter passageway is present in continual open communication between the inlet port and chamber, said passageway bypassing said ball and seat engagement.

Claim 4

The apparatus as recited in claim 2 wherein said inlet port consists of a tubular fitting received within said chamber, said passageway passing through a wall of said fitting.

Claim 5

The apparatus as recited in claim 3 wherein an end of said tubular fitting received within said chamber defines said seat.

Claim 6

Apparatus for dispensing fluids from their original containers and out of a pouring head, comprising: pump means for receiving and forcing the beverages toward the pouring head; reservoir means connected to said pump means for receiving a plurality of the original containers and maintaining the beverages therefrom in common communication with said pump means while restricting intercommunication of the beverages within the containers; an elastically expandable and contractable dispensing line interconnected between said pump means and the pouring head; first valve means interposed in said line for enabling the flow of beverages from the pouring head when open at the beginning of a dispensing cycle and prohibiting such flow when closed at the end of such cycle; second valve means interposed in said line between said pump means and first valve means for prohibiting the flow of beverage from said line and into said pump means, and wherein said second valve means closes after the closing of said first valve means following a dispensing cycle, closing of said second valve means maintaining beverage under pressure within said dispensing line between said first and second valve means; and third valve means interposed in said line between said first valve means and the pouring head for enabling the flow of beverage through said line and out of the pouring head when said first valve means is open and allowing the beverage in said line to slowly withdraw from the pouring head when said first valve means restricts the flow of beverages from the pouring head.

Claim 7

Apparatus for dispensing fluids from their original containers and out of a pouring head, comprising: pump means for receiving and forcing the beverages toward the pouring head; reservoir means connected to said pump means for receiving a plurality of the original containers and maintaining the beverages therefrom in common communication with said pump means while restricting intercommunication of the beverages within the containers; an elastically expandable and contractable dispensing line interconnected between said pump means and the pouring head; first valve means interposed in said line for enabling the flow of beverages from the pouring head when open at the beginning of a dispensing cycle and prohibiting such flow when closed at the end of such cycle; second valve means interposed in said line between said pump means and first valve means for prohibiting the flow of beverage from said line and into said pump means, and wherein said second valve means closes after the closing of said first valve means following a dispensing cycle, closing of said second valve means maintaining beverage under pressure within said dispensing line between said first and second valve means; and third valve means interposed in said line between said first valve means and the pouring head for enabling the flow of beverage through said line and out of the pouring head when said first valve means is open and allowing the beverage in said line to slowly withdraw from the pouring head when said first valve means restricts the flow of beverages from the pouring head.

Claim 8

The apparatus as recited in claim 5 wherein said second valve means comprises: a chamber; an inlet port in communication between said chamber and said pump means; an outlet port in communication between said chamber and dispensing line; and a ball and seat valve within said chamber and maintained at the point of interconnection of said inlet port and chamber.

Claim 9

The apparatus as recited in claim 5 wherein said third valve means comprises: an inlet port in communication with said dispensing line from said first valve means; an outlet port in communication with said dispensing line to the dispensing head; a chamber interconnecting said inlet and outlet ports; and a ball and seat valve maintained with said chamber.

Claim 10

The apparatus as recited in claim 7 wherein a small diameter passageway is present in open communication between said inlet port and chamber for bypassing said ball and seat valve.

Claim 11

A beverage dispenser pumping system for dispensing beverages from their original containers and out of a pouring head, comprising: pump means for receiving and forcing the beverages toward the pouring head; a plurality of receptacles, each in beverage receiving communication with one of the original containers and in common communication, along with all other receptacles along a common flowpath, with said pump means; and an adapter having an orifice therein interconnected between each of the containers and said associated receptacles, communication between the containers and receptacles being through said orifice, the orifice of each of the various adapters being maintained at a different vertical level from the orifice of all other adapters, the vertical position of each orifice being directly related to the position of the associated receptacle to the pump means along said common flowpath such that the orifice communicating with the receptacle nearest the pump means is of the highest elevation and that furthest from the pump means is of the lowest elevation.

Claim 12

A beverage dispenser pumping system for dispensing beverages from their original containers and out of a pouring head, comprising: pump means for receiving and forcing the beverages toward the pouring head; a plurality of receptacles, each in beverage receiving communication with one of the original containers and in common communication, along with all other receptacles along a common flowpath, with said pump means; and an adapter having an orifice therein interconnected between each of the containers and said associated receptacles, communication between the containers and receptacles being through said orifice, the orifice of each of the various adapters being maintained at a different vertical level from the orifice of all other adapters, the vertical position of each orifice being directly related to the position of the associated receptacle to the pump means along said common flowpath such that the orifice communicating with the receptacle nearest the pump means is of the highest elevation and that furthest from the pump means is of the lowest elevation.

Claim 13

A beverage dispenser pumping system for dispensing beverages from their original containers and out of a pouring head, comprising: pump means for receiving and forcing said beverages toward the pouring head; a plurality of receptacles, each in beverage receiving communication with a separate one of the original containers and in common communication, along with all other receptacles, with said pump means; a plurality of adapters, each having an orifice therein, one interconnected between each of the containers and said associated receptacle, communication between the containers and receptacles being through said orifice; and wherein each of said receptacles communicates with the other receptacles and with the pump means via a line of a plurality of sections, each section of a different diameter, and wherein one receptacle is interconnected with each section, the receptacle closest to the pump means being connected to the smallest diameter section, and the remaining receptacles being progressively connected to increasingly larger diameter sections such that the receptacle furthest along the line from said pump means is connected to the largest diameter section.
