摘要

The invention relates to a device for converting a pivoting movement of a pinion (8) into a translational movement of a slide (4), the pinion being pivotally mounted with respect to a support member (10) for the slide comprising a fixed tubular wall (11), the tubular wall being provided with at least one cam surface (15) engaging with a follower roller (16) mounted on a support element (17) which is connected rotationally to the pinion and connected translationally to the slide, characterized in that the pinion is carried by the support member coaxially to the tubular wall. The invention also relates to a valve comprising such a device.
