Sliding component having fluid introduction groove and dynamic pressure generation groove

A sliding component comprising:

• a pair of sliding parts that relatively slide on each other, one of the sliding parts being a stationary-side seal ring, the other of the sliding parts being a rotating-side seal ring, the seal rings each having a sliding face formed radially for sealing liquid or misty fluid which is sealed fluid from leaking, the sliding faces comprising:
• a fluid introduction groove and a dynamic pressure groove;
• wherein the fluid introduction groove and the dynamic pressure generation groove are both provided on the sliding face of the rotating-side seal ring or both provided on the sliding face of the stationary-side seal ring;
• or
• wherein the fluid introduction groove is on one of either the sliding face of the rotating-side seal ring or the sliding face of the stationary-side seal ring and the dynamic pressure generation groove is provided on the opposing sliding face from the fluid introduction groove,
• wherein the fluid introduction groove communicates with a peripheral edge of the sliding face on a sealed fluid side and not a peripheral edge of the sliding face on a leakage side on which it is located;
• wherein the dynamic pressure groove communicates with a peripheral edge of the sliding face on a leakage side and not a peripheral edge of the sliding face on a sealed fluid side on which it is located;
• and
• wherein a positive pressure generation mechanism with a positive pressure generation groove that communicates, at an upstream end, with the fluid introduction groove is provided.
