Rotary valve pneumatic pulsator to induce oscillatory - motion in liquid contained in enclosed vessel

摘要

Rotary valve pneumatic pulsator to induce oscillatory motion in liquid contained in enclosed vessel. GA-. Comprises a pneumatic pulsator mechanism in which a circulator valve disc rotates in a housing with a pressure and an exhaust opening, alternately connecting the vessel with the compressed air supply and with at phere. The valve contains at least one port, and the discharge line from the vessel is coaxial with the discharge line to atmosphere from the rotary valve. The valve may also contain a number of ports in the disc, one pattern of ports being concentric with the other pattern, and one pattern connecting the vessel to the pressure line, while the other connects it to the discharge to atmosphere. Selection of the patterns of the ports enables the type of oscillation of the liquid in the vessel to be controlled.
