An infinitely variable transmission comprising an angular velocity input member (12), an angular velocity output member (14), two parallel stages (18, 20) of cyclic angular velocity generating devices (24, 30), a drive arrangement (16) for applying angular velocity from the input member (12) to each of the angular velocity generating devices (24, 30), extraction devices (26, 32) which are each driven by a cyclic angular velocity generating device (24, 30) in each of the two stages (18, 20) means for varying the amplitude of the cyclic angular velocity produced by at least one of the stages (18, 20) and an arrangement (28, 34, 22) for summing and combining the pulsating angular velocity outputs from the extraction devices (26, 32).
