Abstract
A valve (1, 2) is provided with a movable closing element (16, 116), with a nozzle body (32) with a passage opening (26), as well as a valve seat (25) surrounding the passage opening (26), and with an elastic sealing element (27, 127) which is movable with the movable closing element (16, 116), in order to close or open the valve seat (26), in which, at least when the valve seat (26) is open, a gap (29, 129) is present between at least one section (27a, 127a) of the elastic sealing element (27, 127) and a section (16a, 116a) of the movable closing element (16, 116) lying opposite thereto.
Claims16
A valve (1, 2) comprising:
- a movable closing element (16, 116);
- a nozzle body (32) with a passage opening (26) as well as a valve seat (25) surrounding the passage opening (26);
- an elastic sealing element (27, 127) which is movable with the movable closing element (16, 116) in order to close or open the valve seat (26);
- and
- a compression spring;
- characterized in that at least wherein, when the valve seat (26) is open, a gap (29, 129) is present between at least one section (27a, 127a) of the elastic sealing element (27, 127) and a section (16a, 116a) of the movable closing element (16, 116) opposite thereto,
- wherein the gap (129) is at least partially formed by a step (130) or recess on a side of the elastic sealing element (127) facing the movable closing element 15 (116),
- wherein the gap is present between sections of the elastic sealing element (27, 127) and opposite sections of the movable closing element (16, 116), which extend from an edge of the elastic sealing element (27, 127) towards its center,
- and wherein the movable closing element (16, 116) is supported by the compression spring (19) such that it presses the elastic sealing element (27, 127) against the valve seat (25) when the valve (1, 2) is closed.
