Title:
EMITTER AND DRIP-IRRIGATION TUBE
Document Type and Number:
WIPO Patent Application WO/2018/025681
Kind Code:
A1
Abstract:
This emitter has an emitter body, a film, and a cover. A sealed space is formed between the cover and a portion of the film. A flow channel in the emitter include: a first through-hole that is opened in a first surface and a second surface of the emitter body; and a second through-hole that is disposed downstream of the first through-hole. The film is disposed so as to block first surface-side openings of the first through-hole and the second through-hole. The film becomes distorted toward the side of the sealed space due to deformation caused in the film when the temperature of the film exceeds a preset value and when the pressure of irrigation liquid circulating within the flow channel exceeds a preset value, thereby creating a gap between the emitter body and the film, through which the first through-hole and the second through-hole are enabled to be connected to each other.
