Expansion chamber for pulsed liquid drives with perforated Pulsation tubes.

The invention relates to an expansion chamber for pulsation liquid drives, which a perforated pulsation tube (tubes) on = takes.

It is known to let the pulsation tubes end on the boiler wall (AIiZ-P 26 23 343.2 and AKZ P 26 25 733.o).

The; injecting water jets hit the opposite = overlying boiler wall and spray there.

In this way the water distribution of the incoming cold water = Ser too selective, the vaccine development relatively low and the danger of deterrence large - even if heat transfer fins enlarge the heating surface.

However, if you lead the pulsation tube (s) through the boiler in a narrow chamber (pot), which of course with the interior of the boiler is connected, the heating surface increases considerably.

If the pulsation tube in the boiler and chamber space is also perforated, Then there is also the fact that the water that is injected is distributed over a much larger hot wall surface, which means that more steam is generated more quickly wraps. The pressure increases and the risk of deterrence decreases.

Since more pulsation tubes per boiler are cheaper anyway, you can several expansion chambers tightly. group the fire and separate isolate against heat radiation.

There are some possible variations in the design.

So you can put several pulsation tubes in one chamber but a pipe brings more heating; .

A separate chamber can also be dispensed with and the perforated pulsation tubes can be continued in the boiler in such a way that they run along the heated side of the boiler so that the cold water that is injected is distributed over as large an area as possible.

Finally, it is possible to insert a pulsation tube into a slightly wider tube and connect the outer tube (which is shorter than the inner tube) to the inner tube in a pressure-tight manner at the ends.

The outer tube is "kettle"; the inside is perforated in the boiler!

Finally, the combination is bent into a compact spiral or screw.

The sketches show features and details

1 shows a turbine variant with a forked pulsation tube (1). In the boiler (2) this tube (3) is perforated and leads into an expansion chamber (4). The heat transfer surfaces protrude from it into the chamber.

The valve (5) is on "close" in the direction of the turbine, so this is the pressure phase and the liquid sprays through the branch pipe (3a) via the nozzle (6) against the turbine blades. Noteworthy: only one valve is necessary. The valve offers less resistance to suction than the narrow nozzle, so suction only takes place via the valve. The turbine housing must be cooled.

Fig 2 An expansion chamber is not used here. The perforated pulsation tube (1) is led far into the boiler <2) .

Fig. 3 shows a variant pipe in a pipe. The outer tube (2) is 'boiler' The inner tube (3) is a pulsation tube and is perforated. Both tubes are wound in a spiral.
