Double-acting cylinder piston stirring mechanism pump - is controllable via seat valve rings and has lever-type stirring mechanism for mixing aspirating and pressing

摘要

The controllable seat valve rings (12,6,7) and a pivotable stirring mechanism lever (17) with paddle (18) are in drive connection with a piston connecting rod. Double conically shaped, counterposed cone ring surfaces from a seat valve ring (12), and are sealed on a pre-chamber by means of elastic sealing rings (26). The cylinder piston formed from two seat valve rings (6,7) located against one another with inserted sealing bodies. On one end of the piston connecting rod (2), and by means of a link bearing part (11), a stirring mechanism lever (17) with a bearing rod (15) is pivotally driven, supporting against an adjustable bearing part (16). On the stirring mechanism lever is pivotally located a paddle (18) which is spring-loaded (19). ADVANTAGE - A fully controllable stirring pump with the smallest possible, flow-favourable cross-sectional variations in the suction area, slow running, but stirring intensively and continuously.
