When the pump is to be used, water is thrown in from above, which renders the contact between the elliptical valve or frame and the cylin- der water tight; after a few revolutions the air is exhausted, and the water rising is carried into 6, h, b, 6, and discharged hy d or p' as before described. It is evident the discharge wiU depend conjointly on the velocity and sectional area of the water passing from the jacket into the lunes, and the area of the lunes and the velocity vi'ith which they are formed, or carried round. When the velocity and sectional area at m is suflicient to fill a hme in the time of half a revolution, a maximum eti'ect is produced, and the discharge is found ; when the velocity at m is sufficient to fill the lunes, by multiplying the velocity of the lunes by twice their area of one.
