Abstract (en)
[origin: US5692649A] PCT No. PCT/EP95/00132 Sec. 371 Date Sep. 19, 1996 Sec. 102(e) Date Sep. 19, 1996 PCT Filed Jan. 13, 1995 PCT Pub. No. WO95/19230 PCT Pub. Date Jul. 20, 1995A suction and force pump for a fluid in a sealed fluid container makes possible the drawing off by suction of residual air after the filling of the container with fluid, with the piston (3) in a particular position in the pressure cylinder (8) of the pump, by means of the pump channel (7) of the pump itself. For this purpose there is provided a channel for drawing off the residual air by suction, from the upper side of the fluid container through openings (13), a gap between piston (3) and the internal wall of the pressure cylinder (8), which gap is sealed with respect to the pressure cylinder (8) only by means of a peripheral sealing lip (9), through the pressure chamber (6) to the pump channel (7). The valve (5) to the fluid container is thereby closeable independently of pressure during the pumping away, by means of a plunger (11).
