Ｎが吸込まれる。Together with the conveying air F, auxiliary air N is sucked in via an auxiliary air opening 3 adjacent to the suction air opening 5 but separated from it by a transverse web 6 between the pipe jacket and the partition wall 4. will be included.
最適な搬送条件若しくは所望の搬送量の調節のために、
両方の空気開口３及び５に所属して管軸線に対して平行
に移動可能な共通のスライダ７が配置されている。For optimal conveyance conditions or adjustment of desired conveyance amount,
A common slide 7 assigned to both air openings 3 and 5 and movable parallel to the tube axis is arranged.
特に第２図に示されているように、スライダは差原理に
基づき働く、すなわちスライダは一方の空気開口の開放
横断面を増大せしめるのに対して他方の空気開口を開放
横断面を減少せしめるように移動させられる。In particular, as shown in FIG. 2, the slider works on the difference principle, i.e. the slider increases the opening cross-section of one air opening while decreasing the opening cross-section of the other air opening. be moved to.
両方の空気開口３及び５に所属して、例えば弾性的な適
当な材料から戊りかつ自動的に作動する逆止めフラップ
８若しくは９がそれぞれ配置されている。Associated with both air openings 3 and 5 is a non-return flap 8 or 9, respectively, which is made of a suitable material, for example elastic, and which operates automatically.
逆止めフラップは、例えば吸込ノズルに接続された搬送
導管に急撃に空気が流入し、すなわち負圧が消滅しかつ
場合によっては短詩的に正圧が生ぜしめられた場合に、
ばら物質、特に粉塵（粒子）状のばら物質が空気開口３
若しくは５から流出することを防止する。A non-return flap can be used, for example, in the event of a sudden inflow of air into a conveying conduit connected to a suction nozzle, i.e. the negative pressure disappears and, if necessary, a positive pressure is created.
Loose materials, especially loose materials in the form of dust (particles), are removed from the air opening 3.
Or prevent it from flowing out from 5.
