Tap assembly
A tap assembly 10 with a hollow tap body 16 which defines a dispensing chamber 24 leading to an outlet arrangement 26 . A valve assembly with a valve element 18 is provided to selectively open an inlet into the dispensing chamber 24 . A push button 20 is provided which operates the valve assembly, and which defines an operating chamber 28 , with the push button movable into the operating chamber. A connecting member is provided extending from the push button 20 through the operating chamber. A seal 39 is provided to prevent liquid passing from the dispensing chamber 24 to the operating chamber.
1. A tap assembly, the tap assembly including:
a partially hollow body which defines a dispensing chamber within the partially hollow body with a liquid inlet and a liquid outlet, the liquid inlet being located to receive liquid to be dispensed by the tap assembly, the liquid outlet connecting to an outlet arrangement for the tap assembly;
a valve assembly to selectively open the liquid inlet of the dispensing chamber, the valve assembly including a valve element selectively movable between a position closing the liquid inlet of the dispensing chamber and a position permitting liquid to pass therethrough;
a push button for operating the valve assembly, the push button defining an operating chamber against a part of the partially hollow body, such that as the push button is pushed to operate the valve assembly the push button moves into the operating chamber; and
a connecting member which extends from the push button through the operating chamber, through an opening in the part of the partially hollow body, and into the dispensing chamber to the valve element, the partially hollow body defining an air inlet separate from the outlet arrangement, and an air intake passage which extends from the air inlet to an air outlet connecting to the dispensing chamber spaced from the outlet arrangement, the air intake passage being separated from the connecting member and the push button, and the operating chamber and the air intake passage being connected by a vent.
2. The tap assembly of claim 1 , wherein the air intake passage narrows from the air inlet to the air outlet.
3. The tap assembly of claim 1 , wherein the air intake passage is aligned downwardly and the air outlet is aligned horizontally.
4. The tap assembly of claim 1 , wherein the air intake passage extends around a single side of the opening.
5. The tap assembly of claim 4 , wherein the vent is located on a side of the opening opposite of the side around which the air intake passage extends.
6. The tap assembly of claim 5 , wherein the vent is closer to the air inlet than the air outlet.
