Abstract (en)

[origin: WO0225141A1] The invention concerns a device (2) comprising a slide (9) in the form of a rectangular frame, mobile in translation along its major axis (10), and comprising on the inner surface of each of its major sides a rack-like toothing (14. The slide (9) is engaged about a wheel (15) wedged on a shaft (6) and having a toothed sector (16) meshing successively with one or the other of the two sets of teeth (14) along the moving direction of the slide (9). The sets of teeth (14) have a curvature, or an inclination relative to the major axis (10) of the slide (9). The toothed sector (16) of the wheel (15) has, over its length, a variable distance relative to the geometrical axis (17) of the shaft. Thus a variation in the relationship between the translational speed of the slide (9) and the rotational speed of the shaft (6) is obtained. Said device is applicable to heat engine, particularly spark ignition engines, the slide (9) being linked at least to a piston (5).
