摘要： PURPOSE:To make liquids not to be premixed into an extinguishing liquid and to improve the performance of an extinguisher by providing flexible bags in a container separately, isolating two liquids, and mixing the liquids of both containers at the time of using the extinguisher. CONSTITUTION:When a lever 8 is depressed, a shaft 2a goes down, a valve 2 is opened, and a cutter 3 opens a sealing plate 5. Since the sealing plate 5 is opened, the extinguishing liquid in a bag 4 flows through the opening of the sealing plate 5 into the valve 2. Simultaneously, the other extinguishing liquid in a container 6 goes up in a siphon pipe 7, it flows through a communicating port 9 into the valve 2, both liquids of the bag 4 and container 6 are combined at the valve 2, and the liquid is ejected through a hose nozzle. The mixing ratio of both liquids can be obtained by allowing the opening diameter of the communicating port 9 or the opening diameter of a side port 3a of the cutter 3 to be proper.

摘要： PURPOSE:To freely pull-out a hose in right and left direction by providing a door, which is opened forward with a horizontal hinge shaft, in the front part panel of a hose reel storing part and supporting a hose guide, which is composed of plural rollers, with a shaft line to be orthogonal with the door with being freely turnable on the back of this door. CONSTITUTION:On a panel 2 to cover the front part of a hose reel storing part 1, a door 4 is provided to be opened forward by a hinge 3 of a horizontal shaft and a hose guide 6 is provided on the back of the door 4. For the hose guide 6, two circular arc rollers 5, whose side surface is recessed, are faced each other and shaft-supported to a roller stand 10. Then, a hose 8 is passed between the rollers 5 and the roller stand 10 is freely turned by a shaft line 7 which is orthogonal with the door 4. At the time of use, the door 4 is opened and a nozzle 12, which is received on the back of the door, is put off from the door 4 and runs toward a place, where fire is generated. The rollers are revolved with facing to the right and left sides of the hose 8 and since the stand 10 is freely turned, the hose 8 can be changed by 180 deg. in both right and left directions. Accordingly, in which direction the place to generate the fire exists, the hose can be smoothly pulled out.

摘要： PURPOSE:To enable a fire extinguisher to be usable for a long time by flowing a principal ingredient to a duct main flow part in a fire extinguisher vessel and charging an auxiliary ingredient to its low pressure part and mixing and discharging both ingredients. CONSTITUTION:A differential pressure means using a Venturi tube 2 is arranged in a fire extinguisher vessel 1, and the principal ingredient is flowed to the main flow part of the Venturi tube 2 of this differential pressure means from a siphon tube 7 hanging in the vessel 1. When the auxiliary ingredient stored in a flexible bag 3 is charged to a low pressure part 5 of the Venturi tube 2, both ingredients are mixed in the rear part of the Venturi tube 2 and are discharged from a nozzle of the fire extinguisher. Since they are mixed at the time of the use, though they are degenerated in the state of premix liquid, chemicals having a powerful fire extinguishing effect can be used and the chemical use range of the fire extinguisher is extended.
