© ines split exhaust pipe of the Buchi type with

a split turbine housing.

Mn disliked split turbine housing comprises sswei apiralige ducts, which are each fed with exhaust gases from separate ducts of the exhaust pipe. Each spiral channel distributes gas through a nozzle ring to approximately 180 ° of the tüafang of the Starbinenradee "In the past this nozzle ring was considered indispensable" to increase the speed of the Gaaee when it hit the turbine wheel. The presence of the bushing rings, however, resulted in an external thermal stability and friction losses and thus a lower efficiency of the turbine. In addition, the nozzle rings do not make the production of the 2uroine unit significantly more expensive. -.

The object of the invention is to create a turbine housing which enables the exhaust gases to strike the turbine wheel precisely without the use of bushing rings, while the speed of the exhaust gases is nevertheless increased. This vird at a gas-powered turbine, "it an the housing turbine wheel surrounding two Gaaeinlaßöffnungen, Ernest first in the housing formed arcuate, is inhibitory to the turbine extending and arcuate over a portion of tJmfanges of Turbinenradea towards the latter open channel and a second the turbine adjacent and over a further section of the ümfanges to Turbinenrade3

this Wm open 2aaal _s in accordance with the? B? £ induBg reaches through a first converging channel that is open towards the first arched-shaped turbine wheel with a GaeeinlaSSffmmg connecting the speed of the gases through the gas inlet opening The gas inlet opening connects to the second arcuate channel, which is open towards the larbine wheel, and accelerates the gases fed in through the gas inlet opening before they enter the wide, arched channel. Due to the formation of the converging channels in a surhine housing, the aforementioned minor parts are not eliminated "but the performance of the entire turbine is also made simpler and more economical"

According to a further feature of the invention, the axes of the said converging channels can extend from opposite sides of the turbine wheel section, wherein the axes of the converging channels can also be offset by 180 ° from one another.

Have the same conicity for both converging channels being able to use is, according to another feature, the Invention in the turbine housing formed another channel, the second inlet port converging with the second Koiial connects and through said gas inlet opening supplied gases to the converging channel for acceleration

If the turbine wheel is to be applied precisely to the turbine wheel, a further feature of the invention is that the arcuate channels are each open over 180 ° of the turbine wheel wall on this wheel. According to a further feature of the invention, the arcuate branch of the first arcuate channel in the Uadaufricatung of the Eurbinenrades lies behind the arcuate section of the second arcuate channel.

The invention is based on one in the drawing presented embodiment example nSher described. In this Own drawing:
