<p><P>PROBLEM TO BE SOLVED: To provide an axial controller capable of locking a valve in a plurality of given selected positions with regard to a conventional type multipath valve arranged in a hydraulic circuit. <P>SOLUTION: A controller for controlling movements of a multipath valve 4 used for driving a piston and cylinder assembly is equipped with a switch 7 and a turn switching knob 8. The switch 7 includes a regulating system 105, which is connected to a valve system 5 of the multipath valve operated by a vehicle operator. The regulating system 105 is operatively connected to a tubular body 24, which is energized by a spring 22 to be connected to the turn switching knob 8. The tubular body includes a plurality of vertical grooves 33 and a plurality of annular grooves 25, 26, 27. There are provided balls 28 fitted into the vertical and annular grooves. The balls 28 are housed partially in an annular chamber 30 of another tubular body 29 positioned outside of a radial direction. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
