Title:
Sliding component
Document Type and Number:
Japanese Patent JP6161632
Kind Code:
B2
Abstract:
Provide a sliding component that can prevent generation of deposits by preventing vaporous cavitation from occurring in the pumping groove on the sealing face. It is characterized in that the sealing face of one of a pair of sliding parts that slide relative to each other is provided with a first pumping groove 10 that is open to the high-pressure fluid side but isolated from the low-pressure fluid side by a seal area and also angled to discharge the fluid toward the high-pressure fluid side by sliding relative to the mating sealing face, as well as a second pumping groove 11 that is open to the low-pressure fluid side but isolated from the high-pressure fluid side by a seal area and also angled to discharge the fluid toward the high-pressure fluid side by sliding relative to the mating sealing face, wherein the low-pressure fluid-side end of the first pumping groove is arranged adjacent to the high-pressure fluid-side end of the second pumping groove.
