The high-voltage limiting spring (1332) uses its elastic force to drive the lower end of the high-voltage limiting seat (1333) to seal the opening of the high-voltage limiting groove (26).

2. A rotary check valve for an ultra-high pressure piston pump according to claim 1, characterized in that: The upper end of the low-pressure limiting seat (1323) protrudes in a conical shape to extend into the low-pressure limiting groove (22) and seal the opening of the low-pressure limiting groove (22).

3. A rotary check valve for an ultra-high pressure piston pump according to claim 1, characterized in that: A high-pressure guide hole (29) is provided at the upper inner wall of the high-pressure mounting groove (28). The high-pressure limiting seat (1333) includes a high-pressure limiting outer sleeve (13331) and a high-pressure limiting inner core (13332).
