Title: Gas device and gas cock
Inventor: KAWAGUCHI YOJI
IPC: F23N1/00
Filed: 1989-12-06
Abstract: PURPOSE:To provided so that the thermal power adjustment always return automatically to the position of thermal power 'strong' at the time of reignition by fitting a brake which provides a resisting force proportional to the load to a spring only when a gas device is ignited and used on the outer circumferential face of a thermal power adjusting disk that has outer circumferential faces that have different diameters and is under a load so as to be at the position of thermal power 'strong'. CONSTITUTION:Right after ignition the thermal power is strong and since a brake 9 is at the same position as a cut-out section 3e that is provided in the outer circumferential face of a thermal power adjusting disk in the axial direction, the brake 9 comes smoothly to the position of the outer circumferential face of the thermal power disk. A spring 10 is extended to the position where the thermal power adjusting is at minimum and the load for return becomes maximum. When the thermal power is moved in the direction of 'weak', the diameter of the outer circumferential face of the thermal power adjusting disk that is in contact with the brake 9 becomes larger gradually and a brake adjusting spring 12 is compressed and the resistance by contact becomes large and the position of the thermal power is stable. Here when an operation button is pressed in to carry out a fire extinguishing action, the break 9 is away from the thermal power adjusting disk 3, and it rotates by the spring load, and a thermal power adjusting key returns to the position of thermal power 'strong'. The thermal power is, therefore, always at the position of thermal power 'strong' at the time of reignition.
