Abstract
Tête dans laquelle le piston de travail est formé de deux pistons concentriques mobiles l'un par rapport à l'autre. La tête comporte un piston d'expulsion il et une chambre de mélange 12 de même diamètre. Le piston 11 est solidaire, à l'arrière, du piston 13a entouré du piston 13b qui coulisse dans le cylindre 14 et dont le mouvement par rapport au piston 13a est limité par les butées 40a et 40b. Les composants du mélange sont introduits par les deux ouvertures 16, 16' dans la chambre 12. A ces ouvertures sont associées deux soupapes d'admission 5, 5', avec des cônes 17, 17', des sièges 18, 18' et des ressorts 19, 19'. La tension des ressorts est réglée par les manchons 20, 20'. Les soupapes 5, 5' se déplacent dans des chambres 21, 21'. Le prolongement 42 du piston 13a peut actionner l'interrupteur de fin de course 31 par le poussoir 30.
