Document Type and Number:
WIPO Patent Application WO/2018/105505
Kind Code:
A1
Abstract:
Provided is a sliding component that is capable of simultaneously satisfying opposing conditions of sealing and lubrication when a gas is on the high-pressure fluid side and a liquid is on the low-pressure fluid side. The present invention is characterized by being provided with a pair of sliding components 3, 5 that slide oppositely to each other, wherein a high-pressure gas is present on one side of the pair of sliding components 3, 5 and a low-pressure liquid is present on the other side, a positive pressure generation mechanism 10 provided with a positive pressure generation groove 11 is provided to a sliding surface S of at least the sliding component 5, an annular deep groove 14 is arranged on the high-pressure gas side, and the annular deep groove 14 is isolated from the high-pressure gas side by a land R, and is connected with the low-pressure liquid side through a deep groove 13 in the radial direction.
