Abstract
A rotary throttle member for an internal combustion engine comprises a shaft and a butterfly valve member secured to a central length of the shaft. The shaft and butterfly valve member are single pieces of synthetic material. End portions of the shaft straddle the said central length. The central length has a uniform non-circular cross-section greater than that of the full end portion of the shaft situated on one side of the length. The shaft includes a cam for connection with and winding of a control cable, situated on the other end portion of the shaft. The butterfly valve member has a central hole of complementary cross-section of said central length and is fixed onto the central length.
