Description
また、上記縮径部に関しては、ある程度の軸方向の長さを確保する必要があり、液体流路の縮径部の軸方向の長さ寸法L2を、液体供給口の直径寸法D2とストレート部の直径寸法D1との差(D2−D1)の2倍以上を確保することが望ましい。縮径部の軸方向の長さ寸法L2が短いと、液体流路内の洗浄液の整流が不十分となり、洗浄液の速度の向上の効果が十分に得られなくなる。
Claims (3)
- ノズルチップの先端部に洗浄液を噴射する噴射口を有すると共に、前記ノズルチップ内に軸方向に延びて前記噴射口に連なる液体流路を有してなる洗浄用ノズルであって、
前記噴射口には、V字型に切込まれたV溝が形成されていると共に、
前記液体流路は、先端側に位置し断面円形の直管状をなすストレート部と、前記ノズルチップの基端部に設けられた液体供給口から前記ストレート部の基端まで次第に内径を縮小させていく縮径部とを備えて構成されており、
前記ストレート部の軸方向の長さ寸法L1と直径寸法D1との比(L1/D1)が、7.8以上、15以下とされ、
前記液体流路の縮径部の軸方向の長さ寸法L2は、前記液体供給口の直径寸法D2と前記ストレート部の直径寸法D1との差(D2−D1)の2倍以上とされていることを特徴とする洗浄用ノズル。 - 前記噴射口のV溝の切込み角度は、40°以上、65°以下とされていることを特徴とする請求項1記載の洗浄用ノズル。
- 前記液体流路の縮径部の、軸方向に沿う断面形状は、該液体流路の内側に膨らむ緩やかなR形状とされていることを特徴とする請求項1又は2記載の洗浄用ノズル。
