Abstract

PURPOSE:To obtain a smooth valve working mechanism by inserting balls between grooves provided on the outer surfaces of input and output shafts and a tube body surrounding the input and output shafts to engage the grooves with the tube body. CONSTITUTION:The first groove 13 and the second groove 14 with crossing directions each other are provided on the outer surfaces of an input shaft and an output shaft, and said individual shafts 2, 3 are surrounded by a tube body 15 which is free of movement in the direction of the shaft together with a spool valve 11. The tube body 15 is composed of an outer tube body 15a fixed to the valve 11 and an inner tube body 15b which is provided free of rotation within the outer tube body 15a, and the third grooves 16a, 16b corresponding to the first groove 13 and the second groove 14 are formed inside the inner tube body 15b. Balls 17 are inserted as engaging elements between the first groove 13, the second groove 14 and the corresponding third grooves 16a, 16b, and are arranged so that they get into contact with individual grooves at two points and the lines connecting these two points are in parallel each other.
