The invention relates to a valve top comprising a head piece (1) which is centrally penetrated by a spindle (2) which is rotatably mounted in the head piece (1) around its longitudinal axis and via which a control disk (3) can be rotated relative to an inlet plate abutting the same, wherein a control sleeve (6) having a control contour (63) is arranged within the head piece (1) on the spindle (2), and a guide sleeve (5) having a guide contour (54) is arranged opposite the control contour (63), which control sleeve and guide sleeve interact in such a way that after actuation of the control disk (3) via the spindle (2) into a defined direction, an autonomous return movement of the control disk (3) into its starting position is effected. |
