摘要:
A drip irrigation tube (2) is provided with metering elements (1) comprising respectively inlet regions (4), through which the water in the tube (2) arrives in the metering elements (1), metering regions (6), formed by a labyrinth channel (7), which is delimited by two lateral walls (8), (9), a cover (10) and the walling (3) of the drip irrigation tube (2) and in which a pressure reduction of the water flowing through takes place, and outlet regions (13), through which the water emerges out of the drip irrigation tube via outlet openings (14) made in the tube walling (3). The respective outlet region (13) borders at least on one lateral wall (8), (9) of the labyrinth channel (7) at least one region of this lateral wall is covered by an elastic membrane (15) forming a portion of the cover (10), so that the lateral wall (8) is able to be lifted off of the tube wall (3) by means of the elastic membrane (15) and forms a passage (17) through which the water from the labyrinth channel (7) arrives directly in the outlet region. The water flowing through the metering element (1) can thereby be metered depending upon the water pressure in the drip irrigation tube (2).
