Abstract
A valve control device for controlling the opening and closing of a valve, including a first control arm and a second control arm, wherein the first control arm is arranged to rotate around a first axis at a first end, wherein the second control arm is arranged to rotate around a second axis at a first end, wherein the first axis is perpendicular to the second axis, and wherein the interface between the first control arm and the second control arm includes a fork and a rotatable member, and wherein the centre axis of the rotatable member is parallel to the upper bearing surface and the lower bearing surface of the fork. The advantage is that the wear of the rotatable member is reduced.
