Abstract

1483002 Syringes; discharging liquids by direct air pressure CARL SCHLEICHER & SCHULL K G 10 July 1975 [11 July 1974] 29099/75 Heading F1R The piston 2 of a syringe may be withdrawn from the cylinder by means of a handle 11 until a stop 14 engages the end cap 12, whereby liquid can be drawn through the opening 15 into the chamber 16. The piston 2 is formed with a cylinder 7 in which a piston 4 is reciprocable by the handle 11. The pistons 2, 4 are provided with valves 18, 21 whereby on reciprocation of the piston 4 air is drawn in through valve 21 and discharged through valve 18 into the chamber 16 to free the liquid therein through the opening 15.
