Abstract (en)
[origin: EP1380352A1] Double-acting pump (1) comprises a piston (7) which in the non-operated state releases, under a restoring spring force, an outlet (33) between a pressure chamber (26) and an opening (32) in a housing section (4b). A connecting piece (28) has a valve seat (31) and a valve-closing part (30) which adopts a closing position on the valve seat when the pump is held so that the operating head (12) is lower than the connecting piece and an opening position when the pump is held the other way round. Preferred Features: The valve-closing part is operated under its own weight.
