Apparatus for dispensing flowable substances

摘要

An apparatus for dispensing flowable substances, having a nozzle having an exit opening for dispensing the substances from the nozzle, and a closure part movable by a control element, disposed outside of the nozzle, and configured to release the exit opening and close the exit opening, in the region of a closure part surface that faces the nozzle end. The closure part surface is delimited, in the movement direction of the closure part from the open position to the closed position, by a leading edge, in the leading direction. The closure part surface is disposed next to the nozzle and at a level upstream from the exit opening, with reference to the flow direction of the substances through the nozzle, in the open position. The closure part can be moved from the open position to the closed position by the control element, such that the leading edge of the closure part surface is moved past the free nozzle end.

主权项

1. An apparatus for dispensing flowable substances, comprising:
a nozzle (2) that has an exit opening (4) for dispensing the substances from the nozzle (2) in the region of a free nozzle end (3), a closure part (5) having a closure part surface (33) that faces the nozzle end (3), and a control element (6), disposed outside of the nozzle (2), configured to move the closure part (5), the closure part (5) configured to release the exit opening (4) in an open position and close the exit opening (4) in a closed position, in the region of the closure part surface (33), wherein the closure part surface (33) is delimited, in the movement direction of the closure part (5) from the open position to the closed position, by a leading edge (34), in the leading direction, wherein the closure part surface (33) is disposed next to the nozzle (2) and at a level upstream from the exit opening (4), with reference to the flow direction of the substances through the nozzle (2), in the open position, wherein the closure part (5) is connected to be moved from the open position to the closed position by the control element (6) so that the leading edge (34) of the closure part surface (33) is first moved past the free nozzle end (3) in the direction of the flow of the substances through the nozzle (2), and then the closure part surface (33) is moved to directly contact the nozzle (2) in the region of the exit opening (4), in a direction perpendicular to an exit axis (9) of the exit opening (4) of the nozzle (2).
