Apparatus for shock-like flushing in a liquid system, comprising an accumulating or blocking element (11, 12, 13) which upon supply of liquid from an inlet (7) is adapted to be set from a normal position to a flushing position accummulated liquid flows through an outlet (6B, 6, 6A) to a following section of the liquid system, and subsequently to be ret to normal position. The blocking element (11, 12, 13) is held in an inclined position (11', 12', 13') by means of spring or weight load (21, 22, 23) until a certain level of accumulated liquid is attained, and the spring or weight load (21, 22, 23) is adapted to bring the blocking element (11, 12, 13) back from the flushing position to normal inclined position when a certain low liquid level is attained. The blocking outlet (6B, 6, 6A) respectively, through flexible tube sleeves (15, 14) which make possible the movement of the U-tube (11, 12, 13) between the two positions for accumulation and flushing, respectively.
