<p>The level controller for the liquid level in the water condenser of a linen drying machine includes a membrane valve (1) with holes pulled by a magnetic spring, and operated by a magnet (9) carried by a float (10) in the water container. The valve has a membrane (5) which has a large hole, which may be closed by the magnetic spring, in the centre, and a number of smaller holes around it. These allow the pressure to the supply liquid to help in the opening and closing of the valve.</p> |
