1. A valve (10) for regulating oxygen in a fuel cell system (11), the valve comprising a valve housing (12) with a valve seat (13) and a through-opening (14) in the valve seat (13), and a valve shaft (15) with a valve disk (16) formed thereon for closing the through-opening (14) in the valve seat (13) in a closed state of the valve (10) and for releasing the through-opening (14) in a released state of the valve (10),
wherein
a moving means (17) for linearly moving the valve disk (16) between an opening position in an open state, in which the valve disk (16) is spaced apart from the valve seat (13), and a closing position in the closed state, in which the valve disk (16) is positioned on the valve seat (13), and for rotationally moving the valve shaft (15) in order to pivot the valve disk (16) between the opening position and a releasing position in the released state, in which at least part of the valve disk (16) is spaced farther apart from the valve seat (13) than in the opening position,
wherein the moving means (17) has
a base body (23) for the rotational movement of the valve shaft (15),
a guide means (21) for guiding the valve shaft (15) during the linear movement and for fixing the valve shaft (15) during the rotational movement, and
a locking means (22) for locking a gear wheel (18) on the base body (23) for the rotational movement,
wherein the locking means (22) includes a pin that extends from a side face of the gear wheel (18).
