pumping, by properly positioning the control holes in the channels. In FIG. 1 shows a longitudinal section of the pump; FIG. 2, 3, and 4 cross sections of the pump with indications of oblique channels.

NOSOC consists of a box 15, inside of which a fixed cone 14 is placed, having through oblique channels; the cone 14 is enclosed by a tubular closure 13, equipped with respectively the same through oblique channels and handles 19. Between the box 15 and the closure 13 there is an epiploon 17 with a gasket 26 fixed by a nut 16. The box has
