So that the pawl has a third engagement surface (16) for the adjusting facility, which runs at a side, facing away from the second engagement surface (11). So that the third engagement surface engages at a locking projection (19) of the adjusting facility (20), the projection of which extends in the opening direction of the inlet valve (14). Also so that the adjusting facility with its locking projection is displaceable across an acting on medium (32), relative to the third engagement surface.
