Abstract:
PCT No. PCT/FI92/00317 Sec. 371 Date May 20, 1994 Sec. 102(e) Date May 20, 1994 PCT Filed Nov. 25, 1992 PCT Pub. No. WO93/10859 PCT Pub. Date Jun. 10, 1993In fire-fighting equipment having a drive unit for supplying extinguishing liquid, the drive unit is at least one hydraulic accumulator in which a high initial drive pressure falls to a reduced drive pressure in use. The hydraulic accumulator supplies only the extinguishing liquid at the high initial drive pressure and a mixture of the extinguishing liquid and a gas at the reduced drive pressure. For this, the hydraulic accumulator has a liquid space for the extinguishing liquid and a gas space for the gas that each communicate through an outlet valve with an outlet line for the use. The outlet valve responds to the high initial drive pressure and reduced drive pressure for opening only a liquid outlet connection at the high initial drive pressure and opening also a gas outlet connection at the reduced drive pressure.
