Abstract

The present invention relates to improvements in or relating to air conditioning and other installations, in particular to the removal of condensate and other liquids. We describe a method of preventing siphoning of a liquid through a pump having an inlet and an outlet, which outlet is coupled to a discharge line; the method comprising providing an air inlet valve in the discharge line. We also describe an air-inlet valve comprising a valve body having a liquid inlet and a liquid outlet and a through-bore therebetween further comprising an air-inlet in fluid communication with the through- bore. Preferably, the air-inlet comprises a non-return or one-way valve.

Claims

AMENDED CLAIMS received by the International Bureau on 3 September 2012 (03.09.2012) CLAIMS:
1. A method of preventing siphoning of a liquid through a pump having an inlet and an outlet, which outlet is coupled to a discharge line; the method comprising providing an air inlet valve in the discharge line to admit air to the discharge line as liquid flows through the discharge line.
2. A method as claimed in claim 1 wherein the air-inlet valve is positioned at a height not less than slightly below the height of the outlet of the pump.
3. A device for preventing siphoning of a condensate liquid through a pump, wherein the device comprises a liquid inlet couplable to an outlet of the pump, and wherein the device further comprises a liquid outlet forming a bore through the device with the liquid inlet, wherein the device further comprises an air-inlet in fluid communication with the bore and wherein the air-inlet comprises a uni-directional valve arranged to admit air into the device in response to a flow of condensate liquid through the bore.
4. A device as claimed in claim 3 wherein the valve is a duck-bill valve.
5. A device as claimed in claim 4 wherein the valve is made of an elastomeric material.
6. A device as claimed in any one of claims 3 to 5 wherein the air inlet comprises a cavity in fluid communication with the bore by means of a communicating line.
7. A device as claimed in claim 6 wherein the valve is a duck-bill valve and is held in position within the cavity by means of a retaining cap.
