Abstract
A device for dispensing a flowable medium, includes a housing having a cavity for receiving the flowable medium, a rod mounted in a bearing section of the housing, wherein the rod is movable by means of an actuator between a first end position and a second end position in an axial direction, a dispensing opening, opening into the cavity, for dispensing the flowable medium, wherein the rod has a sealing section, wherein the sealing section closes the dispensing opening in the first end position and is arranged at a distance from the dispensing opening in the second end position, a bellows seal for sealing off the bearing section from the cavity, wherein the rod passes through the bellows seal, wherein the bellows seal is mounted in a sealed manner on the rod and in a sealed manner on the housing, wherein a first section of the bellows seal is connected to the rod in a manner fixed relative to the rod, and a second section of the bellows seal is connected to the housing in a manner fixed relative to the housing, wherein the bellows seal has at least one compensating section for compensating an axial compression or extension of the bellows seal, wherein the compensating section projects radially relative to adjoining regions of the bellows seal, and having at least one channel, opening into the cavity, through which the flowable medium can flow into the cavity, wherein a projection of a center line of a channel section of the at least one channel, said channel section opening into the cavity, onto a projection plane formed perpendicularly to the axial direction forms a circle tangent of a circle formed concentrically with the rod.
