<p>The unti, esp. for actuation of a slide valve carries a release, which engages with a release adjuster, when the slide moves into an end position. Actuation of the release unblocks a locking unit. Elements move the slide into neutral position, when the locking unit is released; and additional elements maintain it in this position, after actuation of the fail safety unit. The additional elements contain a spring which, during normal valve operation, presses the slide into the end position. The slide is actuated by a cable pull, which is normally tensioned by the spring.</p> |
