Definitions

  • the bi-metal member is constrained in the temperature responsive valve to prevent transitioning from the first configuration to the second configuration, but is permitted limited transitioning movement for co-operating with the valve seat of the temperature responsive valve for modulating the flow of fuel gas through the valve.
  • the bi-metal member is responsive to temperature within a predetermined temperature range adjacent the transition temperature for modulating the flow of fuel gas through the temperature responsive valve.
  • the burner unit defines a longitudinally extending main central axis, and the respective delivery axes defined by the first and second nozzles and by the fuel gas inlet to the temperature responsive valve coincide with the main central axis of the burner unit.
  • the respective central axes of the venturi mixing means, the temperature responsive valve and the first and second nozzles coincide with each other.
  • Fig. 11 is a transverse cross-sectional plan view of the portion of Fig. 10 on the line XI-Xl of Fig. 10,
  • the soldering tool 1 is a portable hand-held soldering tool and comprises a main housing 3 of plastics material of circular transverse cross-section, which defines a longitudinally extending main central axis 2.
  • the main housing 3 forms a handle 4 for holding the soldering tool in use.
  • the main housing 3 defines a rechargeable fuel gas reservoir 5 for fuel gas in liquid form.
  • a charging valve 6 is located in an upstream end cap 7 of the main housing 3 for facilitating charging of the fuel gas reservoir 5 with liquid fuel gas.
  • the delivery axes defined by the fuel gas inlet 56, the first nozzle 47 and the second nozzle 60 are all axially aligned with each other, and all coincide with the main central axis 2 defined by the main housing 3.
  • the burner 36 also defines a longitudinally extending central geometrical axis which coincides with the main central axis 2. Accordingly, the temperature responsive valve 38, the second nozzle 60, the venturi mixer 41, the first nozzle 47 and in turn the burner 36 are sequentially located one after the other in a generally downstream direction, and are axially aligned with each other.

Abstract

La présente invention a trait à un outillage de brasage à gaz (1) comportant un boîtier principal (3) formant manche (4) et un réservoir de gaz combustible (5) et définissant un axe principal central (2). Un organe de corps (10) terminé par une pointe d'outillage de brasage (11) forme une chambre de combustion (18) au sein duquel se trouve un élément de combustion catalytique (19) destiné à transformer le mélange gaz combustible/mélange d'air en chaleur pour le réchauffement de la pointe d'outillage de brasage (11). L'organe de corps (10) est rendu solidaire du boîtier principal (3) par un organe de retenue (12), un boîtier secondaire (28) et un écrou presse-étoupe (14) qui rend l'organe de retenue (12) solidaire d'un ensemble en aval de capot terminal (15) du boîtier principal (3). Du gaz combustible en provenance du réservoir est alimenté à la chambre de combustion (18) grâce à un système d'alimentation de gaz combustible (39) qui fournit du gaz combustible à une soupape sensible à la température (38) dans laquelle le flux de gaz combustible est modulé pour le maintient de la température de la pointe d'outillage de brasage (11) sensiblement constante dans une plage de température prédéterminée. La soupape sensible à la température (38) comporte un disque bimétallique circulaire (59) qui coopère avec un organe de soupape (58) et un siège de soupape (57) pour la modulation de l'alimentation de gaz combustible en fonction de la température de la pointe d'outillage de brasage (11). La soupape sensible à la température (38) et un mélangeur Venturi (41) sont en alignement axial l'un par rapport à l'autre de sorte que l'outillage de brasage (1) puisse se présenter sous une forme ultramince et compacte.
