Abstract

A speed variator apparatus, of the trapezoidal belt type that passes over pulleys of progressively increasing diameter by relative axial approach of its conical sides under the thrust of a liquid fluid under pressure acting in an enclosure carried by the pulley and whose admission in this The enclosure, and its exit from it, are under the control of a control valve, characterized in that the transmission ratio it procures is subordinated, to the position of the control member, thanks to the fact that said valve, which controls the intake of the pressurized fluid in said enclosure and its exit from this enclosure, is constituted by a distributor as those used in the hydraulic subordination mechanisms, that is, of the type that operates the control of the passage of the liquid by the relative position of two mobile organs, one of which, the pilot organ, serves as the command organ, and the other, the follower organ, has its position made dependent on the The relative position of the sides is determined by the volume of fluid under pressure in said enclosure.
