Abstract:
     A new transmission device is suitable for hydraulic power reactor. The coolant of reactor-water acts as an active medium. It makes use of the character of the change of cylinder resistance with the movement of the hole of the cylinder in relation to the hole of the piston. The stepping movement of the piston in relation to cylinder is controlled by the flow of water. It doesn't find the high pressure seal problem that often occurs in the general control transmission. It can be perfectly sealed in the pressure shell of the reactor and structure of the reactor is compact.
