溝10b内に水密状態に嵌合する。In assembly, the spherical shaft 20 is fitted in the through hole 42 of the circular partitioning board 40, and the one in which the vane 23 and the swing shaft 26 are fitted in the fitting groove 44 is introduced into the arc-shaped wall 10a. The head 26a of the swing shaft 26 fitted in the guide groove 10b of the arc-shaped wall straddling it over the spherical axis is fitted in the guide groove 10b, and the conical side walls 12, 12a are provided on both sides of the arc-shaped wall. Stick to it. Further, the circumferential wall of the partition board 40 is fitted in the guide groove 10b of the arcuate wall 10a in a watertight state.
従って球軸20は外匣10の貫通口14内に回転自在に貫通さ
れ、主軸30が該球軸の貫通口20b内に嵌合されて後者に
固定され、該主軸の解放窓31a、31bとが該球軸の吸入口

中央部30aの両側でそれより小径の円筒部32a,32bと該貫
通口14との間にローラ・ベアリング18、18を介在させる
ので該主軸は該貫通口20b内で円滑に回転される。Therefore, the ball shaft 20 is rotatably passed through the through hole 14 of the outer casing 10, the main shaft 30 is fitted into the through hole 20b of the ball shaft and fixed to the latter, and the main window release windows 31a and 31b are formed. Is the suction port of the ball shaft
It is arranged so as to face 21 and the discharge port 22. The roller bearings 18, 18 are interposed between the cylindrical portions 32a, 32b having a smaller diameter and the through hole 14 on both sides of the central portion 30a of the main shaft, so that the main shaft smoothly rotates in the through hole 20b. To be done.
円形仕切盤40の案内溝10bは、主軸30の垂直線に対して
約15゜傾斜して形成されている。該仕切盤は外匣10の上
方の案内溝10bで右側の円錐側壁12aと接触し、下方の案
内溝10bで左側の円錐側壁12と接触し、共に水密状態を
保持している。従って外匣10内は仕切線となる該仕切盤
により容積が2分され、その右側の室11と左側の室11a
とに隔離されている。The guide groove 10b of the circular partition board 40 is formed so as to be inclined about 15 ° with respect to the vertical line of the main shaft 30. The partition board is in contact with the right conical side wall 12a in the upper guide groove 10b of the outer casing 10 and in contact with the left conical side wall 12 in the lower guide groove 10b, and both are kept watertight. Therefore, the volume inside the outer casing 10 is divided into two by the partitioning board which serves as a partition line, and the chamber 11 on the right side and the chamber 11a on the left side thereof are divided.
And isolated.
主軸30を他の駆動源(図示せず)により一定方向に回転
させると、該主軸と一体の球軸20が内部貫通口14bでロ
ーラ・ベアリング18を介して回転し、同時に円形仕切盤
40及びそれと一体の扇形ベーン23も回転する。その結果
該扇形ベーンの回転により該主軸の吸入口34bと解放窓3
1aから吸入された流体は球軸20の吸入口21から作動室16
内に導かれ、扇形ベーン23の前方で圧縮される。When the main shaft 30 is rotated in a certain direction by another drive source (not shown), the spherical shaft 20 integrated with the main shaft rotates through the roller bearing 18 at the internal through hole 14b, and at the same time, the circular partitioning machine.
40 and the fan-shaped vane 23 integrated therewith also rotate. As a result, the rotation of the fan-shaped vanes causes the suction port 34b of the main shaft and the release window 3
The fluid sucked from 1a is fed from the suction port 21 of the ball shaft 20 to the working chamber 16
Guided inside, it is compressed in front of the fan vanes 23.
同時に該扇形ベーン及び主軸30に垂直線に対して約15℃
傾斜して回転する仕切盤40により作動室16内の容積が減
少するので、扇形ベーン23の前側にある流体は圧縮さ
れ、球軸20の貫通口22から解放窓31aを経て吐出口34aか
ら吐出される。At the same time, the fan-shaped vanes and the main shaft 30 have a vertical line of about 15 ° C.
Since the volume inside the working chamber 16 is reduced by the partitioning board 40 that rotates in an inclined manner, the fluid in front of the fan-shaped vane 23 is compressed and discharged from the through hole 22 of the ball shaft 20 through the release window 31a and the discharge port 34a. To be done.
その結果扇形ベーン23の背面では作動室16内の容積が増
加するので吸入口34aと解放窓31aから流体を吸入する。As a result, the volume inside the working chamber 16 increases on the back surface of the fan-shaped vane 23, so that the fluid is sucked through the suction port 34a and the release window 31a.
第3図の通り扇形ベーン23が水平位置にある時は、外匣
10内の容積を仕切盤40により2分したのを、更に扇形ベ
ーンにより2分するので、該外匣内を4分割して4室と
なる。As shown in Fig. 3, when the fan-shaped vane 23 is in the horizontal position,
Since the volume inside 10 is divided into two by the partition board 40 and further divided into two by the fan-shaped vane, the inside of the outer casing is divided into four to form four chambers.
該扇形ベーンが更に回転して外匣10の円錐側壁12aと接
触した時、該外匣内の右側の室11は該扇形ベーンにより
分割されないので1室のままであるから、該外匣内は3
室となる。When the fan-shaped vane further rotates and comes into contact with the conical side wall 12a of the outer casing 10, the right-side chamber 11 inside the outer casing is not divided by the fan-shaped vane and remains as one chamber. Three
Become a room.
この様にして球軸20と一体の扇形ベーン23が外匣10内を
回転するので、該外匣内を3〜4分割しながら、該扇形
ベーンが回転する。In this way, the fan-shaped vanes 23 integrated with the ball shaft 20 rotate inside the outer casing 10, so that the fan-shaped vanes rotate while dividing the inside of the outer casing into 3 to 4 parts.
その為該扇形ベーンにそれを跨いて摺動自在に上から嵌
合された揺動軸26が該円形仕切盤40のR面と密着して摺
動自在に嵌合し、該揺動軸が仕切盤40を回転させる。Therefore, the swing shaft 26 slidably fitted over the fan-shaped vane from above is slidably fitted in close contact with the R surface of the circular partition board 40, and the swing shaft is Rotate the partition board 40.
[効 果] 前述の構成を有する回転仕切盤を有するベーン・ポンプ

Since the swing shaft 26 fitted to the fan-shaped vane from above is slidably fitted in close contact with the R surface of the circular partitioning machine to maintain a sufficient watertight state. Fluid suction, compression, and discharge can be performed very effectively.

仕切盤を有するベーン・ポンプ。1. A fan-shaped cross section having an arcuate circumferential wall and a conical side wall and having a bearing formed at the center; and a fan-shaped vane having a through-hole at the center and corresponding to a fan-shaped working chamber in the fan-shaped outer box. Are integrally formed in the longitudinal direction of the circumference, and an intake port and a discharge port, which communicate with the through-hole, are formed in the front and rear of the fan-shaped vane, respectively, and are slidably fitted across the front and rear surfaces of the fan-shaped vane and the head. A ball shaft having a combined swing shaft and rotatably fitted in the bearing; a suction port on one side, the suction port and the discharge port at the through hole of the ball shaft at the center A main shaft fixed to the spherical shaft fitted in the through-hole of the fan-shaped outer casing and rotatably fitted in the through-hole of the fan-shaped outer casing. A circular space having a gentle slope from the center toward the circumference and having a curved surface on the periphery of which the spherical axis is in close contact, and a circle from the circular space A groove having a curved surface in which the fan-shaped vane and the swing shaft are in close contact with each other, and the spherical shaft is closely fitted in the circular space. Further, the fan-shaped vane is fitted in the groove, and is composed of a circular partitioning plate which is inclined and fixed at a constant angle with respect to the main shaft; and the fan-shaped vane integrated with the spherical shaft according to the rotation of the main shaft. By rotating the swing shaft, the front and rear surfaces of the fan-shaped vane and the head are slidably reciprocated, and the inside of the fan-shaped outer casing is divided into 3 to 4 by the circular partitioning board and the fan-shaped vane. The fluid sucked from the suction port of the main shaft is compressed in the working chamber by the circular partitioning plate and the fan-shaped vane, and is discharged from the discharge port through the discharge port of the spherical shaft and the release window of the main shaft. A vane pump with a rotating partitioning panel.
