Proportional valve and also a heating and/or cooling system with a proportional valve
The proportional valve comprises at least one heating water passage 16 controlled by a valve, and at least one potable water passage 18 controlled by a further valve, wherein the valves have valve members 22,28 coupled together, ideally by a rod 32 or springs. A first 22 of the valve members is conn...

| description | The proportional valve comprises at least one heating water passage 16 controlled by a valve, and at least one potable water passage 18 controlled by a further valve, wherein the valves have valve members 22,28 coupled together, ideally by a rod 32 or springs. A first 22 of the valve members is connected to a diaphragm 34 that divides a valve chamber 36 into first 28 and second 40 sub-chamber. The first sub-chamber has a first opening 42 controlled by the first valve member 22 and a second opening 44 narrowed by a venturi assembly 46. A channel 50 is provided from the venturi assembly to the second sub-chamber. A heating and/or cooling system including the proportional valve is also claimed. Ideally the valve has a first passageway 66 controlled by the first valve member and a further passageway 70 controlled by a spring-loaded third valve member 68. The valve ideally has a bypass path 62 having a cross-section adjustable by a screw 64 or slider and which circumvents the venturi assembly. |
