Abstract:
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.
