- the mill function is due to the provision of a rubbing function in the plane between the rubbing surface 20a of the pressure member 2a and the rubbing surface 20b of the impeller 8.
- This rubbing function is performed by cutting each of the side end surface of the partition wall 16 of the case 2 and the side end surface from the boss portion 12 of the impeller 8 to the blade 9, and the rubbing surface such as a sesame mortar or a stone mill. This is achieved by applying a (rough surface) process.

加圧部は、ケースに収容された羽根車の羽根に対向しケースの吸入口側から送出口側に向けて収束するポンプ室を羽根車との間で形成する加圧面と、この加圧面をケースの吸入口側とポンプ室の収束する側との間で仕切り、羽根車のボス部から羽根に至る側端面と接触する側端面を有する仕切り壁とを備え、
羽根車をケースの吸入口側から仕切り壁とは反対側へケースの送出口側に回転させて、試料を含む流体を羽根車の回転方向に移送し、ケースの吸入口側から送出口側に向けて収束するポンプ室によって試料を含む流体を加圧することでケースの送出口から送出する容積型のポンプを構成し、
羽根車のボス部から羽根に至る側端面と、ケースの仕切り壁の側端面のそれぞれに、擦り合わせ面を有し、これらの擦り合わせ面での羽根車の回転による擦り合わせおよび羽根車の羽根によるせん断によって試料を微細化することを特徴としている。
揚程対吐出量の特性曲線が異なる事に注意しなければならない。

- 試料を微細化するための微細化装置であって、
羽根車と、この羽根車を収容し、微細化する試料を含む流体をポンプ室内に吸入する吸入口およびこの流体をポンプ室外に送出する送出口を有するケースとを備え、
羽根車は、円盤状の羽根板と、この羽根板の中心部に設けられ羽根車をケースに回転可能に軸支するボス部と、羽根板の側面でボス部から放射状に突出し、ボス部と面一の側端面を有する複数の羽根とを備え、
ケースは、羽根車をその外周部に沿って収容する円筒状の内周面と、ケースに収容された羽根車の羽根に対向して設けられた加圧部とを備え、
加圧部は、ケースに収容された羽根車の羽根に対向しケースの吸入口側から送出口側に向けて収束するポンプ室を羽根車との間で形成する加圧面と、この加圧面をケースの吸入口側とポンプ室の収束する側との間で仕切り、羽根車のボス部から羽根に至る側端面と接触する側端面を有する仕切り壁とを備え、
羽根車をケースの吸入口側から仕切り壁とは反対側へケースの送出口側に回転させて、試料を含む流体を羽根車の回転方向に移送し、ケースの吸入口側から送出口側に向けて収束するポンプ室によって試料を含む流体を加圧することでケースの送出口から送出する容積型のポンプを構成し、
羽根車のボス部から羽根に至る側端面と、ケースの仕切り壁の側端面のそれぞれに、擦り合わせ面を有し、これらの擦り合わせ面での羽根車の回転による擦り合わせおよび羽根車の羽根によるせん断によって試料を微細化することを特徴とする微細化装置。 - 擦り合わせ面は、切削加工により形成された格子状の溝を有することを特徴とする請求項1に記載の微細化装置。
- 羽根車の羽根は、側端面において長さ方向先端側が羽根車の回転方向に前進傾斜して反るように屈曲していることを特徴とする請求項1または2に記載の微細化装置。
