Valve arrangement

A valve arrangement, comprising:

• a housing with a fluid line;
• a valve arranged in the fluid line having:
• a valve seat;
• a valve opening;
• a valve flap that is pivotable about a pivot axis between a closed position, in which the valve flap lies against the valve seat and closes the valve opening in fluid-tight fashion, and an open position, in which the valve flap opens up the valve opening;
• a shaft configured to pivot the valve flap;
• and
• a protrusion arranged on the valve flap and configured to space the valve flap apart from the shaft,
• wherein the valve flap, in the closed position, defines an X-Y plane of a coordinate system and the pivot axis is arranged with a spacing to the X-Y plane and defining a Y direction of the coordinate system, and
• an alignment mechanism by which an arrangement in which the valve flap is situated relative to the valve seat in the closed position is alignable and fixable at least in an X direction,
• wherein the alignment mechanism configured to fasten the valve flap to the shaft,
• wherein the alignment mechanism has a screw fastening of the valve flap to the shaft,
• wherein the shaft has at least one passage hole, in which a screw of the screw fastening is arranged, and a planar, first abutment surface, which surrounds the at least one passage hole at a side of the shaft facing toward the valve flap and which is braced together with the protrusion arranged on the valve flap by the screw fastening,
• wherein an outer diameter of the screw is smaller than a cross-sectional dimension of the at least one passage hole to allow an alignment in the X-Y plane,
• wherein the shaft has, on a side averted from the valve flap, a second abutment surface which is arranged plane-parallel with respect to the first abutment surface and on which a head of the screw is supported.

A fuel cell arrangement, comprising:

• at least one fuel cell;
• a gas line configured to feed and/or discharge gas to and/or from the at least one fuel cell;
• and
• a valve arrangement, comprising:
• a housing with a fluid line;
• a valve arranged in the fluid line having:
• a valve seat;
• a valve opening;
• a valve flap that is pivotable about a pivot axis between a closed position, in which the valve flap lies against the valve seat and closes the valve opening in fluid-tight fashion, and an open position, in which the valve flap opens up the valve opening;
• a shaft configured to pivot the valve flap;
• and
• a protrusion arranged on the valve flap entirely between the valve flap and the shaft and configured to space the valve flap apart from the shaft,
• wherein the shaft is in direct contact with a longitudinal end of the protrusion,
• wherein the valve flap, in the closed position, defines an X-Y plane of a coordinate system and the pivot axis is arranged with a spacing to the X-Y plane and defining a Y direction of the coordinate system, and
• an alignment mechanism by which an arrangement in which the valve flap is situated relative to the valve seat in the closed position is alignable and fixable at least in an X direction,
• wherein the valve is configured to shut off the gas line by adjustment of the valve flap into the closed position.

A motor vehicle, comprising:

• a line;
• a valve arrangement, comprising:
• a housing with a fluid line;
• a valve arranged in the fluid line having:
• a valve seat;
• a valve opening;
• a valve flap that is pivotable about a pivot axis between a closed position, in which the valve flap lies against the valve seat and closes the valve opening in fluid-tight fashion, and an open position, in which the valve flap opens up the valve opening;
• a shaft configured to pivot the valve flap;
• and
• a protuberance arranged on the valve flap entirely between the valve flap and the shaft and configured to space the valve flap apart from the shaft,
• wherein the shaft is in direct contact with a longitudinal end of the protuberance,
• wherein the valve flap, in the closed position, defines an X-Y plane of a coordinate system and the pivot axis is arranged with a spacing to the X-Y plane and defining a Y direction of the coordinate system, and
• an alignment mechanism by which an arrangement in which the valve flap is situated relative to the valve seat in the closed position is alignable and fixable at least in an X direction,
• wherein the valve arrangement is configured to shut off the line by adjustment of the valve flap into the closed position, the line being one or more of a gas line of a motor vehicle drive and/or of a fuel cell arrangement of the motor vehicle.
