연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

An oscillating water sprinkler, comprising: a spray structure having a plurality of outlets; a support structure which supports said spray structure, said spray structure being movable in relation to said support structure in an oscillating pattern of movement; an inlet supported by said support structure and configured to be coupled to a hose; and a valve mechanism interposed between said inlet and said plurality of outlets, said valve mechanism defining a water flow aperture providing fluid communication between said inlet and said plurality of outlets, wherein, during said oscillating pattern of movement, said spray structure oscillates in relation to said support structure between a first position and a second position, wherein, as said spray structure moves between said first position and said second position during said oscillating pattern of movement, said support structure passes through a central position, and wherein, as said spray structure moves from said central position to one of said first position and said second position during said oscillating pattern of movement, (i) said water flow aperture increases in size, and (ii) said water flow aperture never decreases in size. 2. The oscillating water sprinkler of claim 1, wherein said spray structure includes a spray tube defining said plurality of outlets. 3. The oscillating water sprinkler of claim 1, wherein said valve mechanism includes: a first valve component attached in fixed relation to said support structure, said first valve component defining a first aperture, a second valve component attached in fixed relation to said spray structure, said second valve component defining a second aperture, and said first valve component is positioned adjacent to said second valve component such that said first aperture is at least partially aligned with said second aperture to collectively define said water flow aperture. 4. The oscillating water sprinkler of claim 3, wherein said second valve component moves in relation to said first valve component during movement of said spray structure between said first position and said second position. 5. The oscillating water sprinkler of claim 1, wherein: said water flow aperture possesses a first size when said spray structure is positioned at one of said first position and said second position, said water flow aperture possesses a second size when said spray structure is positioned at said central position, and said first size is larger than said second size. 6. The oscillating water sprinkler of claim 1, wherein: said spray structure also has a supplement group of outlets, said spray structure defines (i) a first lumen that is in fluid communication with said plurality of outlets, and (ii) a second lumen that is in fluid communication with said supplemental group of outlets, said valve mechanism includes a first valve component attached in fixed relation to said spray structure, said first valve component defining (i) a first aperture that is in fluid communication with said first lumen, and (ii) a second aperture that is in fluid communication with said second lumen, said valve mechanism further includes a second valve component attached in fixed relation to said support structure, said second valve component defining a third aperture, said first valve component is positioned adjacent to said second valve component such that (i) said first aperture is at least partially aligned with said third aperture to collectively define said water flow aperture, and (ii) said second aperture is at least partially aligned with said third aperture to collectively define a secondary flow aperture, said water flow aperture provides fluid communication between said inlet and said first lumen, and said secondary flow aperture provides fluid communication between said inlet and said second lumen. 7. The oscillating water sprinkler of claim 6, wherein: said water flow aperture possesses a first size when said spray structure is positioned at one of said first position and said second position, said water flow aperture possesses a second size when said spray structure is positioned at said central position, and said first size is larger than said second size. 8. The oscillating water sprinkler of claim 7, wherein: said secondary flow aperture possesses a first area when said spray structure is positioned at one of said first position and said second position, said secondary flow aperture possesses a second area when said spray structure is positioned at said central position, and said first area is substantially the same as the second area. 9. The oscillating water sprinkler of claim 1, wherein said spray structure is configured to advance water through said plurality of outlets in a substantially vertical direction when said spray structure is positioned at said central position. 10. The oscillating water sprinkler of claim 1, wherein, during movement of said spray structure from said central position to one of said first position and said second position, said water flow aperture continuously increases in size. 11. An oscillating water sprinkler, comprising: a spray structure having a plurality of outlets; a support structure which supports said spray structure, said spray structure being movable in relation to said support structure in an oscillating pattern of movement; an inlet supported by said support structure and configured to be coupled to a hose; and a valve mechanism interposed between said inlet and said plurality of outlets, said valve mechanism defining a water flow aperture providing fluid communication between said inlet and said plurality of outlets, wherein, during said oscillating pattern of movement, said spray structure oscillates in relation to said support structure between a first position and a second position, wherein, as said spray structure moves between said first position and said second position during said oscillating pattern of movement, said support structure passes through a central position, wherein, as said spray structure moves from said central position to said first position during said oscillating pattern of movement, (i) said water flow aperture increases in size, and (ii) said water flow aperture never decreases in size, and wherein, as said spray structure moves from said central position to said second position during said oscillating pattern of movement, (i) said water flow aperture increases in size, and (ii) said water flow aperture never decreases in size. 12.
