摘要： A flushing mechanism includes a housing with an outfall made at the housing bottom surrounding an axis; a guide rod with axial restraint relative to the housing along the axis; a first piston that hermetically slips on the cylindrical inner surface and guide rod at the same time along the axis direction; a spring loading the first piston installed in the upper cavity surrounding the guide rod; the second piston that hermetically slips on the guide rod along the axis direction and locates between the first piston and the housing bottom; a spring loading the second piston installed surrounding the guide rod; control valve; lower part of the first piston is provided with ring protuberance. The large seal ring of seal assembly of the second piston is sealed over the small seal ring of seal assembly of the second piston.
