摘要： Disclosed is an improvement to a direct pressure regulator including a timer device, transmission means, and a valve controlling the gas flow. The improvement is characterized in that the transmission means that transmits power from the timer device to the valve includes an indirect transmission member that transmits the power indirectly rather than directly as in the prior art. The structure allows the assembly of the constituent parts of the direct pressure regulator to be much more easily accomplished. No adjustment or calibration is needed after the assembly. Manufacture cost and fault rate are both significantly reduced.
