AUTOMATIC DRAIN VALVE
A drain valve assembly comprising: a valve housing (100) having an inlet port (200) and an outlet port (300) and a water collection chamber (400) between the inlet port and the outlet port, and a poppet valve (500) positioned in the water collection chamber (400) and arranged to be normally sealingly positioned across the outlet port to prevent water exiting the water collection chamber to the outlet port, the poppet valve attached to a pressure diaphragm (600) across the water collection chamber (400) such that when the pressure in the water collection chamber exceeds a predetermined opening pressure it causes the diaphragm to lift and to lift the poppet out of sealing engagement across the outlet port such that water can drain to the outlet port from the water collection chamber; wherein the poppet valve has a hollow body defining a channel (550) from a first end (501) of the poppet valve, adjacent the outlet, and a second end (502) of the poppet valve, and wherein the housing defines a vacuum cavity (110) across the second end of the channel, such that a negative pressure acting on one end of the poppet valve is balanced by a negative pressure acting in the opposite direction at the other end.
