SLIDE COMPONENT
First Claim
1. A slide component comprising:
- a pair of slide parts that relatively slide on each other,one of the slide parts being provided, on a low-pressure side of a sealing face thereof, with a negative pressure generation mechanism comprising a negative pressure generation groove, the negative pressure generation groove communicating with a high-pressure fluid side and being separated from a low-pressure fluid side by a land portion,the other of the slide parts being provided, in a sealing face thereof, with at least one interference groove communicating with the high-pressure fluid side for producing pressure variations in a fluid in the negative pressure generation groove, the at least one interference groove having an end on an inside-diameter side extending to a position to radially overlap the negative pressure generation groove.

Abstract
In an embodiment, a slide component includes one slide part 5 provided, on a low-pressure side of a sealing face thereof, with a negative pressure generation mechanism 10 including a negative pressure generation groove 10. The negative pressure generation groove 10a communicates with a high-pressure fluid side and is separated from a low-pressure fluid side by a land portion R. Another slide part 1 is provided, in a sealing face thereof, with at least one interference groove 15 communicating with the high-pressure fluid side for producing pressure variations in a fluid in the negative pressure generation groove 10a. The at least one interference groove 15 has an end 15a on an inside-diameter side extending to a position to radially overlap the negative pressure generation groove 10a.
