Claim:
A slide valve, comprising a multi-part housing defining a passage opening, a first part of said housing including a groove alongside the passage opening and a second part of said housing including a groove alongside the passage opening; a slider plate movable partly in said housing to open and close the passage opening; and a longitudinal seal arranged in each of said grooves, said longitudinal seal in said groove in said first part of said housing having an elastic sealing profile, a first bar adjacent said sealing profile on a first side of said sealing profile, and a second bar adjacent said sealing profile on a second side of said sealing profile, said sealing profile including two sealing lips on a front side spaced apart from one another and arranged to touch said slider plate, a first side piece arranged on a rear side behind said first bar, a second side piece arranged on a rear side behind said second bar, a longitudinal indentation extending between said first and second side pieces, and chambers in a central region on both sides, said longitudinal indentation having a depth such that when said slider plate closes the passage opening and said sealing lips are touching said slider plate, said longitudinal indentation ceases to exist due to compression of said sealing profile.
