Abstract

Slide valve (1), in particular for a waste heat recovery system of a combustion engine, having a valve housing (4), wherein an inlet passage (5) and an outlet passage (6) are formed in the valve housing (4). A substantially cylindrical slide (3) is guided in a longitudinally movable manner in a guide bore (20) in the valve housing (4), wherein the guide bore (20) can be connected hydraulically to the inlet passage (5) and to the outlet passage (6). A closing body (35, 35a) is arranged on the slide (3), wherein a slide seat (75, 75a) is formed between the guide bore (20) and the closing body (35, 35a). The guide bore (20) and the sliding body (35, 35a) form a sliding pair, wherein the sliding pair has the material combination steel-graphite or the material combination ceramic-graphite.
