Dispensing devices with multiple-way tap

A device for dispensing fluid through at least one delivery outlet, comprising:

• at least one first source for at least one first fluid;
• at least one second source for at least one second fluid;
• first flow control means operable between open and closed positions for controlling flow of said at least one first fluid from said at least one first source to said at least one delivery outlet;
• second flow control means operable between open and closed positions for controlling flow of said at least one second fluid from said at least one second source to said at least one delivery outlet;
• disenabling means comprising a first chamber for passage of said at least one first fluid between said first flow control means and said at least one delivery outlet, a second chamber for passage of said at least one second fluid between said second flow control means and said at least one delivery outlet;
• flexible diaphragm means between said first and second chambers, so that when said first flow control means is operated to an open position thereof, pressure of said at least one first fluid in said first chamber displaces said flexible diaphragm means into a closed position for inhibiting the flow of said at least one second fluid from said second chamber to said at least one delivery outlet;
• and
• said at least one delivery outlet comprising second duct means having one end portion connected to said second chamber, and first duct means disposed coaxially within said second duct means and having one end portion passing through said second chamber and said diaphragm means and communicating with said first chamber.

• flexible diaphragm means between said first and second chambers, so that when said first flow control means is operated to an open position thereof, pressure of said at least one first fluid in said first chamber displaces said flexible diaphragm means into a closed position for inhibiting the flow of said at least one second fluid from said second chamber to said at least one delivery outlet;
• valve means between said first chamber and said at least one delivery outlet movable between open and closed positions for controlling the flow of said first fluid;
• and
• valve setting means for setting said valve means to open at a predetermined pressure exceeding the pressure required in said first chamber to operate said flexible diaphragm means into said closed position thereof.

• at least one second source for at least one second fluid;
• first flow control means operable between open and closed positions for controlling flow of said at least one first fluid from said at least one first source to said at least one delivery outlet;
• second flow control means operable between open and closed positions for controlling flow of said at least one second fluid from said at least one second source to said at least one delivery outlet;
• disenabling means operatively connected to at least said first flow control means for inhibiting flow of said at least one second fluid through said second flow control means when said first flow control means is in said open position thereof;
• and
• said at least one delivery outlet comprising two separate coaxially extending ducts forming a single integrated delivery pipe means so that said flows of first and second fluids from said first and second flow control means, respectively, are prevented from mixing with each other.
