FIELD: mechanical engineering, applicable in mechanisms and tools operating on compressed fluid media. SUBSTANCE: the starting valve has a handle, stopper, tapered rotary plug with an axial orifice and additional orifices. The axial orifice is made as a through one at the level of the external passage for feeding the working fluid. The diameter of the additional orifices is less than the diameter of the external passage for feeding the working fluid. One of the additional orifices is located at the level of the inlet of the external passage for feeding the working fluid, the other - on the side of the bottom of the tapered rotary plug. EFFECT: enhanced reliability of valve operation. 2 dwg
