The invention relates to an engine control valve () which comprises a rotatable actuator (), a valve (), and a movement transformation device () suitable for transforming the rotation of the actuator () into translation of the valve (). The movement transmission device () comprises a helical link with uniform pitch for translating the valve ().

Valve comprising a movement transformation device

The invention relates to A device for transforming a rotation of a gear into a translation of a slide, the device including a supporting member provided with a fixed tubular wall translatably connected to the slide by a cam channel, the gear being rotatably mounted on the supporting member and rotatably connected to the slide which is suitable for pivoting about an axis. The gear comprises a ring rotatably mounted on the tubular wall of the supporting member.

Movement transformation device and valve comprising such a device

The invention relates to a device for converting a rotational movement into a translational movement, said device comprising: a first element () that is rotated around a stationary center of rotation () by a rotation means (); a second element () that is translated along a translation axis () by rotating the first element (); a cam () that is rigidly connected to the first element (), said cam () having a cam channel () in which a roller () moves, wherein said roller is rigidly connected to the second element (). Said device is characterized in that the cam channel () has an inner surface () for contact with the roller (), said roller () being in contact () with the inner contact surface () when the first element () is rotated in a first rotational direction (), said inner contact surface () defining a curve of the type developing from a circle.
