Abstract
A manually operable discharge pump for media is operable in a normal position and in an inverted position. A duct means 57b carries the medium. At least one valve 12b substantially closes and opens at least one duct 57b, and the valve 12b has a deformable valve body 44b cooperating with a valve seat 45b, the valve body being arranged between the valve seat and an opposite facing support face 56. The valve body 45b opens by a deformation motion providing an opening position and a closing position of the valve 12b. The valve body 54b is provided by a disk-like spring washer inserted between the valve seat 45b and the facing support face 56.
