Patent ID: 8905331

Claim:
A water saving valve comprising: an upstream side link mechanism part for linking the valve to a water pipe; a water receiving flask part for receiving tap water from the water pipe; a tapered hole part linked at an end thereof to the downstream side of the water receiving flask part with the cross-sectional area of its flow path gradually decreasing toward the other end thereof; a conduit part linked at one end thereof to the other end of the tapered hole part and having a large diameter section of a large outer diameter at the one end side, a small diameter section of a small outer diameter at the other end side and a flow path running along an axial part thereof from the one end to the other end with a uniform cross-sectional area, the large diameter section having an air suction port running through from the axial part to the outer peripheral surface; a sleeve having a support body part rigidly securing part of an axial hole to the conduit part and an eaves-like section surrounding the outer peripheral surface of the large diameter section having the air suction port with a gap for introducing air from the outside; and a downstream side link mechanism part for linking the sleeve to a downstream side piping.
