Valve module with an integrated electric actuator, said module comprising, on the one hand, a valve device comprising a movable member, the positioning of which controls the circulation of a fluid in at least two circulation lines (5, 5') that pass through said valve device, and, on the other hand, an actuator that is able and intended to move the rotary movable member of the valve device rotationally about an axis, the valve device comprising a support body that houses said at least one movable member mentioned above, which forms a cam that is guided in rotation and provided with at least one control surface (7, 7'), and also at least two conduit portions (8, 8') that form local segments of the circulation lines (5, 5'), these conduit portions (8, 8') and this movable member being arranged and configured such that said at least one control surface (7, 7') can come into engagement with and modify, by way of local squeezing, the passage sections of said at least two conduit portions (8, 8'), specifically in a manner that is mutually differentiated and dependent on the rotational position of the movable member, the valve module being characterized in that the actuator consists of a micro-servomotor mounted on the support body, the movable member maintaining its rotational angular position when not actively acted upon by said micro-servomotor, in that said device is formed of two components that are assembled with one another, specifically a functional component formed by the micro-servomotor, the output shaft of which bears the member forming the rotary cam and which has the one or more control surfaces (7, 7'), and a structural component formed by the support body in the form of a U-shaped frame, in that the micro-servomotor is attached to the sides of the U-shape, and in that the conduit portions (8, 8') of said at least one pair of conduit portions have elastically deformable walls, are arranged on or housed in the base (6") of the U-shape, which forms a cradle, and each rest against at least one surface (60, 60', 60") that is perpendicular to the direction of the squeezing force exerted by the cam when it comes into engagement with the conduit portion (8, 8') in question. the valve device comprising a support body that houses said at least one movable member mentioned above, which forms a cam that is guided in rotation and provided with at least one control surface (7, 7'), and also at least two conduit portions (8, 8') that form local segments of the circulation lines (5, 5'), these conduit portions (8, 8') and this movable member being arranged and configured such that said at least one control surface (7, 7') can come into engagement with and modify, by way of local squeezing, the passage sections of said at least two conduit portions (8, 8'), specifically in a manner that is mutually differentiated and dependent on the rotational position of the movable member, the valve module being characterized in that the actuator consists of a micro-servomotor mounted on the support body, the movable member maintaining its rotational angular position when not actively acted upon by said micro-servomotor, in that said device is formed of two components that are assembled with one another, specifically a functional component formed by the micro-servomotor, the output shaft of which bears the member forming the rotary cam and which has the one or more control surfaces (7, 7'), and a structural component formed by the support body in the form of a U-shaped frame, in that the micro-servomotor is attached to the sides of the U-shape, and in that the conduit portions (8, 8') of said at least one pair of conduit portions have elastically deformable walls, are arranged on or housed in the base (6") of the U-shape, which forms a cradle, and each rest against at least one surface (60, 60', 60") that is perpendicular to the direction of the squeezing force exerted by the cam when it comes into engagement with the conduit portion (8, 8') in question.
