<p>{Problem} To provide sliding parts that do not leak when stopped, operate under fluid lubrication and prevent leakage when rotating, including during initial rotation, and are capable of striking a balance between seal tightness and lubrication. {Solution} A plurality of pumping areas for generating pumping action via the relative rotational sliding of a stationary ring and a rotating ring is 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;
the 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 the 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.</p> |
