PURPOSE:To adjust the cam face with simple structure by employing a chain link cam for pressure control valve to be used in remote control of vessel engine interlocked with telegraph transmitter. CONSTITUTION:In a regulation cam system 10, a fan-shaped cam fixing board 11 is provided with tubular elongated holes 12 corresponding in number with exchange of speed command, where a chain link cam 13 is fixed through a sleeve and coupling bolt to each elongated hole. With correspondence to the speed which is different for different type of main machine, it is adjusted by an adjusting bolt 18 for every speed command. The cam face A of the chain link cam 13 is set to such shape as corresponding to the speed of vessel. Consequently, the delivery pressure of an air pressure control valve 9 is controlled in accordance to the amount commanded through an operational handle 3 of telegraph transmitter 1 to produce required main machine rotation. |
