Abstract (en)
[origin: EP0441377A2] In a manually operated sprayer for liquids, the piston (6) of a piston pump, which piston can be displaced by means of a handle (3) counter to the force of a restoring spring (5), has two annular seals (8, 9) which can be distanced axially from one another with such a spacing that a ventilation line (32), which opens into its annular intermediate space (34), for a reservoir which is connected to the sprayer is sealed with respect to the pump chamber (7) both in the position of rest and in the maximum displacement position of the piston by the one annular seal (8) and is sealed with respect to the open end of the pump cylinder (10) by the other annular seal (9), in which case outside the position of rest there is a connection to the atmosphere only via a ventilation groove (37) formed in the wall of the pump cylinder. <IMAGE>
