<p>The adjustable valve has a valve block with a flow opening adjacent to the valve seat on which the valve head engages under the force of a rearwardly mounted spring. The tension of the spring can be adjusted to vary the opening characteristics of the valve and the damping. The support face (21) has a rest stop (33,35,39) in operational connection with it. The rest assembly is step- adjustable so that the preload on the spring can be varied and the force of the spring on the valve head (123) changes. The spherical rest body (39) can engage in a profiled recess (35). The rest stop assembly can have a rotatable drive shell (19) working with the shell of the support face (23), so that the displacement of the shell adjusts the support face and axially adjusts the preload through a drive transmission (27,29).</p> |
