Claims (13)

  1. Bec de gaz comprenant une vanne de sécurité (2), un thermocouple à détection de flamme (3) et un circuit d'alimentation électrique pour vanne de sécurité pour l'allumage du bec de gaz, ladite vanne de sécurité (2) étant directement alimentée par le thermocouple à détection de flamme (3) et ledit circuit d'alimentation électrique (1) comprenant un condensateur (5) qui est chargé à partir d'une source d'alimentation (Vr), qui se charge avec l'énergie stockée dans ledit condensateur (5), en raison dudit chargement, un signal électrique (E) qui est utilisé pour alimenter temporairement ladite vanne de sécurité (2) afin de la maintenir ouverte, ledit chargement du condensateur (5) étant réalisé en activant momentanément un commutateur (6, 6') pour connecter temporairement le condensateur (5) à ladite source d'alimentation (Vr), ladite activation du commutateur (6, 6') se produisant en même temps que l'activation du bec de gaz, caractérisé en ce que l'énergie fournie à la vanne de sécurité (2) est l'énergie stockée dans le condensateur (5), adaptée au moyen de dispositifs de conditionnement (4), lesdits dispositifs de conditionnement (4) convertissant le signal électrique (E) obtenu de l'énergie stockée dans le condensateur (5), en un signal de sortie électrique (S) qui est directement appliqué à ladite vanne de sécurité (2) pour l'alimenter et la maintenir ouverte.
  2. Bec de gaz selon la revendication 1 où ledit condensateur (5) est toujours connecté au dispositif de conditionnement (4).
  3. Bec de gaz selon la revendication 1 où ledit commutateur (6') est un permutateur (6') disposé pour connecter le condensateur (5) à la tension alternative du réseau (Vr) ou au dispositif de conditionnement (4), le condensateur (5) étant connecté à la source électrique (Vr) afin de le charger lorsque le commutateur (6') est momentanément activé et le condensateur (5) étant connecté au dispositif de conditionnement (4) lorsque le commutateur (6') n'est pas activé ou se trouve en position de repos, pour rendre possible sa décharge électrique lorsque le condensateur (5) est chargé.
  4. Bec de gaz selon l'une quelconque des revendications précédentes, qui comprend un bouton-poussoir (7) pour activer le bec de gaz, ledit bouton-poussoir (7) agissant sur ledit commutateur (6, 6') pour l'activer momentanément lorsque ledit bouton-poussoir (7) reste momentanément enfoncé.
  5. Bouton poussoir selon l'une quelconque des revendications précédentes qui comprend un générateur d'étincelles (8) qui est connecté à la source électrique (Vr) lorsque ledit commutateur (6, 6') est activé afin de générer une étincelle pour allumer le bec de gaz.
  6. Bec de gaz selon la revendication 3 ou 4 lorsqu'elle dépend de la revendication 3 où le dit circuit alimente une pluralité de vannes de sécurité (2, 2a, 2b, ..., 2n) et comprend un commutateur (6', 6'a, 6'b, ..., 6'n) pour chaque vanne de sécurité (2, 2a, 2b, ..., 2n), lesdits commutateurs (6', 6'a, 6'b, ..., 6'n) étant connectés d'une manière telle que le condensateur (5) se charge lorsque l'un des commutateurs (6', 6'a, 6'b, ..., 6'n) est connecté, et ledit condensateur (5) se connecte au dispositif de conditionnement (4) seulement quand aucun des commutateurs (6', 6'a, 6'b, ..., 6'n) connecte le condensateur (5) à la source électrique (Vr).
  7. Bec de gaz selon l'une quelconque des revendications précédentes qui comprend un redresseur et un limiteur (9) pour le chargement du condensateur (5).
  8. Bec de gaz selon la revendication (7) où le redresseur et le limiteur (9) comprend une diode Zener (D1) avec un transistor (Q1) connecté sous forme d'émetteur-suiveur, de telle manière que ledit transistor (Q1) serve de conducteur jusqu'à ce que le condensateur (5) atteigne une tension déterminée (Vc).
  9. Bec verseur selon l'une quelconque des revendications précédentes, où les dispositifs de conditionnement (4) comprennent un oscillateur (11) qui réceptionne un signal du condensateur (5), un transformateur (12) qui reçoit le signal de sortie dudit oscillateur (11) et un redresseur (13) qui reçoit le signal de sortie dudit transformateur (12) et génère le signal de sortie (S) que la vanne de sécurité correspondante (2) reçoit.
  10. Bec de gaz selon la revendication 9 où les dispositifs de conditionnement (4) comprennent également un régulateur (10) par lequel une tension décroissante est générée à partir du signal d'entrée (E), ladite tension décroissante étant perçue par l'oscillateur (11).
  11. Bec de gaz selon la revendication 10 où le redresseur (13) comprend une diode (D) pour chaque vanne de sécurité (2).
  12. Bec de gaz selon la revendication 10, où le redresseur (13) comprend un transistor bipolaire (Q) pour chaque vanne de sécurité (2), le transformateur (12) comprenant une seconde bobine (12b) par laquelle la base de chaque transistor (Q) est excitée.
  13. Bec de gaz selon les revendications 9 ou 10, où le redresseur (13) comprend un transistor MOSFET (Q1) avec une faible résistance entre source et débit, pour chaque vanne de sécurité (2) et un circuit générant un signal de maintien (14), le transformateur (12) comprenant une deuxième bobine (12b) qui est utilisée pour alimenter le circuit générateur de signal de maintien (14).
