Patent KR-20010021775-A (KR)
IPC: A01G25/02
Filed: 1999-05-11
Abstract: High performance low discharge emitter (1) of a meander-like form, created by the addition of a thin vane (7) between the edges (4) of two successive reflectors (2) of the meander like path. The vane (7) interferes parallel to the primary flow of the water, is not in contact with the meander-like path, and creates around it two channels, a narrow one and a wide one enabling water to pass. Due to the arrangement of the meander-like form and the vane (7), all the quantity of water passes only through the high performance narrow channel, whereas the wide channel remains stand-by and inactive. Thus, a high water pressure drop is achieved, so that water discharge of the emitter (1) is reduced, and for ensuring a parallel connected wide stand-by path automatically activated as a by-pass in the case of blockage of the narrow high performance operating channel.
