Abstract
Description
−前記燃焼チャンバの長手軸に平行に、前記燃焼チャンバの両端部の一方の端部の延長上に延在し;
−これもまた、ほぼ円筒形、または略円筒形であり、かつ前記燃焼チャンバの断面より短い断面を持ち;
−前記拡散チャンバを通過するガスの濾過を行なうためのガス濾過手段を含まないことを特徴とする。
−前記燃焼チャンバ及び前記拡散チャンバは同じ軸に沿って延在する;
−前記拡散チャンバの断面は、前記燃焼チャンバの断面の約2分の1より短い;
−前記燃焼チャンバは基本的に、頂部が開放されたボックス形部品、及びこの頂部を閉鎖する蓋部材により画成され、前記蓋部材は前記拡散チャンバとの一体化部材を形成する;
−前記発生器には、所定のガス圧に前記燃焼チャンバ内において達したときにのみ通路を形成する少なくとも1つの保護キャップが配設される;
−前記保護キャップは、2つのチャンバの間の遷移領域に配置される;
−前記保護キャップは、前記拡散チャンバの内部に延在し、そして前記排気孔を密閉する。
