Definitions
- the present invention which is part of this context, aims to provide a servo motor meeting this need.
- FIG. 2 is a partial sectional view of a booster according to the second embodiment of the invention.
- the membrane 5 is formed by a sleeve folded back on itself, and air circulation channels are provided between the membrane 5 and the internal face 110 of the cylinder 11.
- the air circulation channels consist of crossed grooves 60, which are hollowed out in the internal face 110 of the cylinder 11.
- the membrane 5 can be obtained by cutting from an extruded tube, that is to say at a very low cost price.
