Title (EN) DELAYED TENSION VALVES
(FR) SOUPAPES A FORCE DE PRESSION RETARDEE
Abstract:
(EN) A valve arrangement comprising a reciprocable valve (4) which is biased into a closed position by a spring (3) disposed between two spring seats (1 and 2) whose separation in the direction of movement of valve (4) is variable. Respective levers (8, 10 and 9, 11) are operatively coupled to the seats (1 and 2) and are simultaneously operated by a cam disc (25) to move the valve to its open position whilst maintaining the separation between the seats (1 and 2) during at least an initial portion of the opening movement.
(FR) Agencement de soupapes portant une soupape (4) à mouvement alternatif qui est sollicitée dans une position fermée par un ressort (3) disposé entre deux sièges (1 et 2) de ressort dont l'espacement dans le sens du mouvement de la soupape (4) est variable. Des leviers respectifs (8, 10 et 9, 11) sont couplés de manière fonctionnelle au siège (1 et 2) et sont actionnés simultanément par un disque à came (25) pour amener la soupape à sa position ouverte tout en maintenant l'espacement entre les sièges (1 et 2) durant au moins une partie initiale du mouvement d'ouverture.
