Sliding parts

Sliding parts for allowing opposing sealing faces of an annular stationary ring fixed on a fixed side and an annular rotating ring that rotates along with a rotating shaft to rotate relative to one another, thereby sealing a sealed fluid present on one side in the radial direction of said relatively rotational sealing faces;

• the sliding parts being characterized in:
• a plurality of pumping areas for generating pumping action via the relative rotational sliding of said stationary ring and rotating ring being discontinuously formed in a circumferential direction on a sealing face of one of the stationary ring and rotating ring so as to communicate with a sealed fluid-containing space;
• said plurality of pumping areas being provided with intake pumping areas operating in a direction in which the sealed fluid is drawn in and outflow pumping areas operating in a direction in which the sealed fluid is expelled;
• and
• a plurality of dynamic pressure-generating grooves for generating dynamic pressure via the relative rotational sliding of said stationary ring and the rotating ring being formed in a circumferential direction on a sealing face of the other of the stationary ring and the rotating ring so as to communicate with the sealed fluid-containing space.
