Abstract

Mechanical actuation system (2) for in-line selector valves (1), comprising: a rotary actuator (3); a first camshaft (5), rotatably driven by the rotary actuator (3), comprising one or more cams (52) adapted to move one or more selectors (12) comprised in the selector valve (1); a second camshaft (6) rotatably driven by the first camshaft (5) through two gears (50, 60) fitted to said camshafts (5, 6), the latter being mutually synchronous, and comprising one or more cams (62) adapted to move the selectors (12) comprised in the selector valve (1); a plurality of sliders (7) adapted to mechanically act upon the selectors (12) according to the action exerted by the camshafts (5, 6) through their respective cams (52, 62). The first camshaft (5) and the second camshaft (6) are parallel to each other and stacked along a first axis (Z). Each slider (7) comprises a follower (72) so designed that its upward movement occurs upon contact with a cam (62, 52) of a rotating camshaft (6, 5); while its downward movement occurs upon contact with another cam (52, 62) of another rotating camshaft (5, 6). The camshafts (5, 6) are so designed that, for each follower (72) of each slider (7), the cams (52, 62) are so shaped as to provide continuous contact between said follower (72) and one cam (52, 62) at all times during the rotation of said camshafts (5, 6).
