Abstract
Official abstract text for this publication.
A hand pump ( 16 ) includes a housing ( 22 ) having an inlet ( 18 ) and an outlet ( 26 ) and an actuating body ( 32 ) movably mounted in the housing axially and a membrane ( 46 ) with a flexible ring section ( 48 ) surrounding the stroke axis ( 34 ). During stroke movement, the actuating body ( 32 ) is pressed with the membrane ( 46 ) against the force of an elastic element ( 42 ) from a resting position (I) into the pump housing ( 22 ) and into an actuating position, and returned to the resting position (I) by the elastic element ( 72 ). Thus, the volume of a pump chamber ( 20 ) can be modified.
