<p>PCT No. PCT/SE84/00313 Sec. 371 Date May 3, 1985 Sec. 102(e) Date May 3, 1985 PCT Filed Sep. 27, 1984 PCT Pub. No. WO85/01537 PCT Pub. Date Apr. 11, 1985.A flushing system for rapidly delivering a given volume of water supplied to an accumulating chamber (5) from an automatically or manually operated valve (6) has a float-controlled discharge valve (19) which is arranged to be opened when said given volume of water has been delivered to the accumulating chamber (5) and the float is located at a corresponding level in said chamber. A supply pipe (13) extends downwardly in the accumulating chamber (5) towards the outlet (3), and a valve housing (19) is slidably arranged, together with the float, on the water supply pipe. In a closing position of the valve housing, the lower edge part of the valve encircles the outlet. In an opening position of the valve housing, with water in the accumulating chamber, the valve housing is lifted from the seating. The lower end of the supply pipe is formed with a valve body (17) arranged, together with the valve housing, to form a pressure chamber (24) having a leakage opening. The supply pipe is provided above the valve body with an opening (18 ) which communicates with the accumulating chamber in the closing position and which communicates with the pressure chamber when the valve housing is lifted from the seating.</p> |
