Description

P at en τ claims:

1. In the case of jet fans and jet exhaustors, the mechanical connection of the regulating device the suction opening with that of the driving air in such a way that there is a change of the cross section of the suction opening also a similar change in the cross section the supply of the driving air, in general how in relation? on Fig. ι was explained.

2. In the case of jet blowers, the mechanical connection of a throttle valve in the suction opening with a spindle in the propellant nozzle, in such a way that when the flap is opened the conical spindle is lifted and when Schliefsen is lowered, whereby an enlargement respectively. Reduction of the outflow cross-section the same is produced, generally as shown in Fig. 2 and explained in the description was.

For this purpose ι sheet of drawings.

1880. Class 27. ERNST KÖRTING in HANOVER. Innovations to jet fans and exhaustors. Patented in the German Empire on October 15, 1880. The innovations are in blasting machines for the movement of air-shaped bodies the regulation of the quantity of the kind of air drawn in at the same time as the regulation of the quantity the driving air type by mechanical connection of the two regulating devices. The regulating mechanism for the type of air drawn in consists of a throttle valve, Cock or valve, that of the driving air type from a throttle valve, cock, valve or movable nozzle needle. Both mechanisms are generally spatially close close to each other, and their mechanical connection consists of levers and coupling rods, Wheel connection, rollers and chain, rope or belt transmission, all arranged in such a way that the reduction or enlargement of the cross section of the suction opening also the reduction respectively Increase in the amount of the driving air coming into effect in the wake Has. The attached drawing shows the typical execution of this mechanical connection represent. Fig. Ι shows a jet fan in which the suction opening regulirbär by a throttle valve is also the cross section of the supply pipe of the driving air type. The detail construction the fan itself is of no importance to the practice of the invention, either as far as the nozzle arrangement is concerned, as well as the position of the suction opening and the feed the driving air against each other. A is the fan, B the driving nozzle, C the throttle valve of the suction opening, D the suction tube, E the throttle valve for regulating the cross section of the supply tube of the driving air type. Both throttle valves carry a crank on the axis of rotation, and the cranks are connected to one another by a coupling rod, so that the rotation of one axis necessarily entails that of the other. Instead of the throttle valve, slide valves, cocks or valves can be used, and instead of a crank and coupling rod, the mechanical connection can be mediated by a toothed arch or cable transmission. Fig. 2 shows a jet fan in which the regulation of the suction opening by a throttle valve, the cross section of the driving nozzle by a conical spindle which is moved up and down in the driving nozzle and is connected by rods and lever transmission with the regulating mechanism of the suction opening. The same letters mean the same construction parts as in Fig. 1. When the throttle valve C is opened or closed, the spindle in the drive nozzle rises and falls and increases or in this way reduces the cross-sectional opening of the same. Instead of the flap C , a slide can be used. The special construction of the fan and the position of the individual main parts relative to one another are of no importance to the invention; on the contrary, any deviations from the drawing can be made therein.
