Patent ID: 8011290

Claim:
A three-way valve provided with an inlet, a first outlet and a second outlet wherein the three-way valve is provided with a first member which is freely moveable, under the influence of a liquid flow from the inlet to the first outlet and/or the second outlet, between a first and second extreme position wherein the first member can move, under the influence of the liquid flow from the inlet to the first outlet and/or the second outlet, from the first extreme position towards the second extreme position and in the second extreme position closes off the first outlet so that the liquid flow then extends from the inlet to the second outlet and the first member can move, under the influence of gravity, from the second extreme position towards the first extreme position when the liquid flow from the inlet ceases, wherein the three-way valve is further provided with a second member which is freely moveable, under the influence of a liquid flow from the inlet to the second outlet, between a third and fourth extreme position wherein the second member can move, under the influence of the liquid flow from the inlet to the second outlet, from the third extreme position in the direction of the fourth extreme position, the second member can move, under the influence of gravity, from the fourth extreme position to the third extreme position when the liquid flow from the inlet ceases and in the third extreme position, the second member blocks a liquid flow from the second outlet in the direction of the inlet, wherein the first member is heavier than the second member.
