Description _V. *

Four-way emissors are one in central heating technology "Known valve that is intended to ensure that, on the one hand, the door running water to the heater (line 3) has a certain temperature receives, and on the other hand, the return water to the boiler (line 2) by adding hot feed water in temperature is increased. This latter effect should cause the heat exchanger surfaces in Keep the boiler as high as possible so that the flue gases from the oil burner on the heat exchanger surfaces of the Boiler does not condense or condense as little as possible «If the heat exchanger surfaces are too cold and condensation as a result The sulfur-containing flue gases on the surface of the heat exchanger surfaces arise from the gaseous sulfur oxide compounds liquid sulfur compounds, which attack the boiler material due to their aggressiveness and at an early stage can destroy.

The four-way mixer should provide a remedy here · How already mentioned, it is supposed to cause water to flow out of line Ί (between boiler and mixer) into a partial flow up to line 3 and a partial flow down to line 2 divides. During the movement of the stream of water into line 3 and its mixture with return water from the line 4 by the energy applied by the circulating pump takes place properly, the movement is a partial flow from line 1 into line 2 is often associated with difficulties. The reason is that the warmer and thus specifically lighter water in line 1 does not naturally endeavor to to migrate down into line 2 * On the contrary, it tends to migrate upwards, which is from the function of the so-called gravity heating can be proven.

An even more important reason, however, is the pressure conditions at the nozzle of the four-way mixer. The return water from the heater flows into the mixer, partly downwards

into line 2, through the boiler and through the / Line 1 to the mixer * This movement of the water is associated with a pressure loss in the direction of the water flow. It can be seen from this that the pressure at point A when entering the mixer is lower than at point B when it exits from the mixer »There is the pump in the supply line has no effect on an additional circulation flow between the return line (line 2) and the boiler no energy available that could cause water to enter sufficient amount flows from point Ä with the lower pressure to point B with the higher pressure

The subject of this application is a device that causes the energy required for this without additional Auxiliary sources is taken from the water flow itself. There are known devices that are attached to the return port (point B) act and through the injector effect an entrainment of water from point A should cause «Since the water velocities but are relatively small, the injector effect is low, the amount of water entrained from point A is therefore small and often the temperature effect cannot be measured at all «

The present application relates to a guide device which sits on the flow connection of the four-way mixer and is able to directly absorb the energy from the flowing water and to use without detour via an injector effect »Das vom Water entering the boiler flows into the mixer nozzle (1), is divided at the guide device and moves in two partial flows up and down «The guide device (2) can be designed so that an almost complete separation into an upper chamber (3) and a lower chamber (4) take place «The water flows are mixed for the flow to the Heating in the nozzle (5) and for the return to the boiler in the Connection (6) «The amount of water that flows into the connection (1) is determined for a specific system by the position of the regulating wheel or control flap (7) determines “If the control flap closes the connection (5) very far, little boiler flow water will flow from nozzle (1) to nozzle 05), the flow velocity in nozzle (1) is therefore small, therefore it is dem

Claims (5)

Flow energy inherent in water at the nozzle (1) is also small. In this state, therefore, there would be little The boiler flow water flows from the connector (1) to the connector (6). But since in this state also from the nozzle (8) to Connection (6) the amount of return water flowing is small, a little boiler flow water from the connection (1) by one is sufficient To bring about a temperature increase in the nozzle (6) » If, on the other hand, the Eegel flap (7) releases a large cross-section from the nozzle (1) to the nozzle (5), a lot flows Boiler feed water into the connection (5)> this also creates a high flow velocity in nozzle (1) and the The high flow energy inherent in the boiler flow water in this state causes a lot of hot boiler flow water from nozzle (1) to nozzle (6) flows »This means that the amount of return water flowing from nozzle (8) to nozzle (6) can from the heating to a higher (temperature.
