そこで以下に本発明の詳細を実施例に基づいて説明する。   Therefore, details of the present invention will be described below based on examples.

図１は本発明の一実施例を示すものであって、計量機の管路Ｐに接合可能な筒状の第一ハウジング部１と筒状の第二ハウジング部２とで構成され、それぞれの一端でねじ部３、４により固定可能に構成され、後述するプロペラに対向する領域には窓５が形成されている。   FIG. 1 shows an embodiment of the present invention, which is composed of a cylindrical first housing part 1 and a cylindrical second housing part 2 that can be joined to a pipe P of a weighing machine. A window 5 is formed in a region facing a propeller, which will be described later.

また、それぞれのハウジング１、２の他端は流路Ｐに接続可能な形状に構成、すなわち第一ハウジング１は流路の端部を勘合可能なテーパ状の通孔６が、また第二ハウジング２の端部は通孔の外周がテーパ状の凸部７に整形されている。   Further, the other ends of the respective housings 1 and 2 are configured to be connectable to the flow path P, that is, the first housing 1 has a tapered through-hole 6 capable of fitting the end of the flow path, and the second housing. At the end of 2, the outer periphery of the through hole is shaped into a convex portion 7 having a tapered shape.

第一ハウジング１の内面には一端側、つまり第二ハウジング２と対向する側から他端側に向けて他端側に段差８を形成するように円筒状の凹部９と、窓５を挟むように円環溝１０、１０が形成され、この溝にＯリング１１、１１が装てんされている。   A cylindrical recess 9 and a window 5 are sandwiched between the inner surface of the first housing 1 so as to form a step 8 on one end side, that is, from the side facing the second housing 2 to the other end side. Are formed with O-rings 11 and 11.

この段差８にはプロペラ１５の回転軸の一端を支持する軸受け板１２が装てんされ、Ｏリング１１、１１と液密状態を維持できる程度の外径を有し、かつ後述する他方の軸受け板１３を装てんしたとき第二ハウジング２を接合固定した状態でも図２（ａ）に示したように軸受け板１３が若干スライドできる程度の間隙Ｇを形成できる長さの耐油性透明材の円筒１４が軸受け板１２を固定するように挿入されている。   This step 8 is provided with a bearing plate 12 that supports one end of the rotating shaft of the propeller 15, has an outer diameter that can maintain a liquid-tight state with the O-rings 11, 11, and the other bearing plate 13 described later. As shown in FIG. 2 (a), a cylinder 14 made of an oil-resistant transparent material having a length capable of forming a gap G that allows the bearing plate 13 to be slightly slid even when the second housing 2 is joined and fixed. It is inserted so as to fix the plate 12.

軸受け板１２、１３に支持されるプロペラ１５は、図３に示したように回転軸１６を有し、軸受け板１２、１３に対向する領域には軸受け板１２、１３のスリーブ１２ａ、１３ａに挿通可能な細径部１７、１７が形成されて段差部１８、１８が設けられ、軸受け板１２、１３のスリーブ１２ａ、１３ａに挿通された状態では段差部１８、１８で回転可能ではあるが軸方向の移動がある程度制限されている。   The propeller 15 supported by the bearing plates 12 and 13 has a rotating shaft 16 as shown in FIG. 3, and is inserted into the sleeves 12a and 13a of the bearing plates 12 and 13 in a region facing the bearing plates 12 and 13. Possible small diameter portions 17 and 17 are formed and step portions 18 and 18 are provided. When inserted into sleeves 12a and 13a of bearing plates 12 and 13, the step portions 18 and 18 can be rotated by the step portions 18 and 18, but in the axial direction. Movement is limited to some extent.

プロペラ１５の回転軸１６の細径部１７の一方を、一方の軸受け板１２つまり下方となる軸受け板１２で支持させた状態でもう他方の軸受け板１３をプロペラ１５の回転軸１６の細径部１７に挿通させるように円筒１４の端部に支持させて第二ハウジング２をパッキン１９を挿入してねじ部３、４で螺合接続すると、第二ハウジング２の端面と軸受け板１３との間に若干の間隙Ｇ、つまり軸受け板１３から回転軸１６が抜け出さず、かつ軸受け板１３が若干スライドできる程度の間隙ｇを確保できるように配置されている。つまり、軸受け板１２の外径は、第一ハウジング１の内径よりも小さく、かつ円筒１４の内径よりも大きく構成されている。   One end of the small diameter portion 17 of the rotating shaft 16 of the propeller 15 is supported by one bearing plate 12, that is, the lower bearing plate 12, and the other bearing plate 13 is supported by the small diameter portion of the rotating shaft 16 of the propeller 15. When the second housing 2 is supported by the end of the cylinder 14 so as to be inserted into the cylinder 17 and the packing 19 is inserted and screwed together with the screw parts 3 and 4, the end face of the second housing 2 and the bearing plate 13 are connected. Are arranged so that a slight gap G, that is, a gap g that prevents the rotating shaft 16 from coming out of the bearing plate 13 and allows the bearing plate 13 to slide slightly. That is, the outer diameter of the bearing plate 12 is configured to be smaller than the inner diameter of the first housing 1 and larger than the inner diameter of the cylinder 14.

これにより、ハウジング１，２による軸方向の過度な圧縮力が円筒１４に作用するのを防止して円筒の破損を防ぐことができる。   Thereby, it is possible to prevent an excessive compressive force in the axial direction by the housings 1 and 2 from acting on the cylinder 14 and prevent the cylinder from being damaged.

軸受け板１２、１３は、一方の軸受け板１３に例にとって説明すると、図２（ｂ）に示したように回転軸１６が挿通される領域は中心部に軸１７の端部側に突出するスリーブ１３ａとして形成され、流体の流通孔１３ｂとが形成され、スリーブ１３ａの根元の内面側にはＲ（アール）部１３ｃが形成されている。   The bearing plates 12 and 13 will be described by taking the one bearing plate 13 as an example. As shown in FIG. 2B, the region through which the rotating shaft 16 is inserted is a sleeve that protrudes toward the end of the shaft 17 at the center. 13a, a fluid circulation hole 13b is formed, and an R (R) portion 13c is formed on the inner surface side of the root of the sleeve 13a.

この実施例において、給油装置の吐出管に接続して容易に視認できる位置に配置したり、流路に連通させて給油ノズルの近傍に配置して液を流下させると、軸受け板１２、１３の流通孔１２ｂ、１３ｂを流体が通過し、プロペラ１５が流れを受けて回転する。このとき流れに渦が存在しても回転軸１６はその両端を支持されているため、回転軸１６は軸受け板１２、１３に可及的に垂直に支持されて安定に支持され流れに対応させてプロペラを回転させる事ができるため、流れの状態が正確に把握できる。   In this embodiment, the bearing plates 12 and 13 can be connected to the discharge pipe of the fueling device and disposed at a position where they can be easily seen, or in the vicinity of the fueling nozzle in communication with the flow path to cause the liquid to flow down. The fluid passes through the flow holes 12b and 13b, and the propeller 15 receives the flow and rotates. At this time, even if a vortex is present in the flow, the rotating shaft 16 is supported at both ends thereof, so that the rotating shaft 16 is supported as vertically as possible on the bearing plates 12 and 13 and is stably supported to correspond to the flow. Because the propeller can be rotated, the flow state can be accurately grasped.

また一方の軸受け板１３は間隙Ｇにより回転軸１６に垂直方向にスライド可能なため軸受け孔であるスリーブ１３ａと回転軸１７との噛み込みを防止できる。また、回転軸１６は、スリーブ１２ａ、１３ａで広い面積で支持できるため回転軸１６の姿勢の安定性が向上する。さらにスリーブ１２ａ、１３ａの根元の内側にＲ部１２ｃ、１３ｃが存在することにより最も摩擦する部位である回転軸１６の段差部１８の磨耗を低減できる。   Further, since one bearing plate 13 can slide in the direction perpendicular to the rotating shaft 16 by the gap G, it is possible to prevent the sleeve 13a which is a bearing hole and the rotating shaft 17 from being caught. Further, since the rotation shaft 16 can be supported by the sleeves 12a and 13a in a wide area, the stability of the posture of the rotation shaft 16 is improved. Further, the presence of the R portions 12c and 13c inside the roots of the sleeves 12a and 13a can reduce the wear of the step portion 18 of the rotary shaft 16, which is the most frictional portion.
