Abstract

Depression advance device for ignition distributor of internal combustion engine, which includes a first chamber containing a flexible membrane connected to the plate or moving lever of the distributor's breaker by means of a traction rod in such a way that the displacement Axial stem modifies the ignition point to obtain curves that present a variation stage during which the ignition point increases rapidly, and a second chamber containing a flexible membrane connected to a movable stop, respectively comprising the first and the second chambers, a first and a second inlet intended to connect respectively and consecutively to a source of depression, so that they are subjected to a depression that acts against respectively a first and a second elastic organ, characterized in that an adjustable adjustable stop in rotation of the plate or moving lever of the switch-holder is arranged so that it can be supported on the mobile stop of the membrane of the second chamber when the value of the depression in the first chamber is less than a predetermined value, because the second elastic member is mounted with an initial compression tension such that, when the adjustable stop and the mobile stop are in mutual contact and when the depression in the first chamber has a value lower than the predetermined value, this second elastic member prevents the rotation of the switch-holding lever under the action of the depression in the first chamber but in such a way that said second elastic member can yield when the second chamber is subjected to a depression of a value greater than the predetermined value, and because a valve is provided at the junction between the second chamber and the source of depression of threshold arranged to apply only the depression to the second chamber when the value of this depression becomes higher than the value r predetermined, in order to abruptly contract the movable stop and consequently release the movable plate or lever whose rapid angular displacement under the action of the depression prevailing in the first chamber abruptly increases the ignition point.
