る。A conventional example of an elbow-shaped pump will be explained based on FIGS. 1 and 2. In these figures, a cast iron blade ratio l, in which a large number of blades 1b are radially provided around the outer periphery of a cylindrical boss 1a, is eccentrically surrounded by a cylindrical casing 2 8.
In addition, a disc-shaped boat plate 8 facing the end face of the impeller l, and a side cover 4 are fixedly attached to the end face of the casing 2 via the boat plate 8.

間４ｂから排出するようになっている。The working water injected into the casing 2 from the water supply port 4C is pressed against the inner circumference of the casing 2 by the centrifugal force caused by the rotation of the impeller 1 to form a water ring 5.
The outer periphery of the blade ratio l and the laparotomy of the casing 2 are sealed. In this water seal shape, a knee cavity 4Lf is created in the center of the inner chamber of the casing 2, partitioned radially by the blade lb, and the blade ratio l is eccentric to the casing 2 and rotates at the r position, so as the blade jlL1 rotates. As a result, the cross-sectional area of each of the spaces is reduced, and the internal air is compressed and discharged by JL (JL), so that air is sucked through the intake port 4a and exhausted from the exhaust gap 4b.

できる。FIG. 8 shows the blade ratio of the Elmo type pump according to the present invention. The impeller in this figure is formed by lateral spirals. In the center of the outer periphery of the blade ratio, a reinforcing annular plate 32 or a metal plate or a plastic plate is used depending on the water of Bengami. Ii! By reducing the thickness of d4tt and te31, the corresponding range of pump performance can be increased.
