、側板１０及びシール部材３の透孔２１と１９を介して
出口１３から吐出する。The sealing member 3 and the side plate 10 in contact with the sealing member 3 are provided with through holes 18, 19 and 2 which are particularly connected to the port 12 and the outlet 13, respectively.
0 and 21, the impeller 7 is rotated by the output shaft 16,
When the blade 8 is compressed by the flat surface 9, the volume within the adjacent blades 8, 8 is reduced, increasing the pressure of the internal fluid, and exiting through the through holes 21 and 19 of the side plate 10 and the sealing member 3. Discharge from 13.
羽根８が平坦面９を過ぎると、羽根８，８間の容積が急
膨張し、透孔１８，２０を介して入口１２から流体を吸
入する。When the vanes 8 pass the flat surface 9, the volume between the vanes 8, 8 rapidly expands, sucking in fluid from the inlet 12 through the through holes 18, 20.
このように本考案によるときは、胴部機筺２ａと端部機
筺２ｂとの間に通常介在されるシール部材３を該端部機
筺２ｂの内側４の略全面を覆うべく大面積のものとし、
これで該端部機筺２ｂの内側４に形成した凹室５をカバ

た流体が凍結してその体積が膨張してもシール部材３が
凹室５の内方に凹入して凍結による流体の体積膨張が吸
収され、当該ポンプの破損を防止出来る効果がある。In this way, according to the present invention, the sealing member 3, which is normally interposed between the body machine casing 2a and the end machine casing 2b, has a large area so as to cover substantially the entire inside 4 of the end machine casing 2b. As a matter of fact,
This covers the concave chamber 5 formed on the inner side 4 of the end machine casing 2b, and furthermore, the side plate 10 attached to one side of the housing 6 housing the impeller 7 is attached to the A through hole 22 communicating with the inside of the housing 6 is provided at a position facing the shaft end, and the through hole 22 is arranged opposite to the recessed chamber 5 via the sealing member, so that there is no space inside the pump housing 2. Even if the filled fluid freezes and expands in volume, the sealing member 3 recesses into the concave chamber 5 to absorb the volumetric expansion of the fluid due to freezing, thereby preventing damage to the pump.
更に、本考案によるときは、シール部材３を端部機筺２
ｂと側板１０とで挾持するようにしたので、流体が凍結
しない通常の運転時にハウジング６内の流体の圧力によ
って該シール部材３が変形するようなことがなく、シた
がってシール部材の周縁のみを支持するようにしたもの
に比して、該シール部材３の寿命が長くなる効果がある
。Furthermore, according to the present invention, the sealing member 3 is attached to the end machine casing 2.
b and the side plate 10, the seal member 3 is not deformed by the pressure of the fluid in the housing 6 during normal operation when the fluid does not freeze, and therefore only the peripheral edge of the seal member This has the effect that the life of the sealing member 3 is longer than that of the sealing member 3 supported by the sealing member 3.
