摘要： 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.

摘要： The invention relates to a turbine (20) having an impeller (23) arranged in a housing (26). The turbine (20) has an inflow region (21) and an outflow region (22) and a working medium flows through said turbine during operation. The working medium flows into the inflow region (21), along a front side (23a) formed on the impeller (23) and subsequently out of the outflow region (22). There is a pressure drop at the front side (23a) between the inflow region (21) and the outflow region (22). A pressure distributer (9) is arranged on the rear side (23b) of the impeller (23), opposite the front side (23a). The pressure distributer (9) comprises a slide ring (31), which cooperates with the rear side (23b) of the impeller (23) and thereby forms a vapour-lubricated throttle. A first flow path (51) runs through the throttle, wherein the throttle hydraulically divides the rear side (23b) into a first region (231) and a second region (232). The first region (231) borders the inflow region (21), and the second region borders a pressure chamber (11). During operation, the inflow region (21) is applied with a higher pressure than the pressure chamber (11). The slide ring (31) is axially moveable. A sealing ring (33) arranged in a groove (41) cooperates with the slide ring (31). A second flow path (52) runs from the inflow region (21) to the pressure chamber (11) between the groove (41) and the slide ring (31). The second flow path (52) can be closed by the sealing ring (33). The sealing ring (33) can be moved in the groove (41) in a defined manner.

摘要： The invention relates to a turbine (20) having an impeller (23) arranged in a housing (26). The turbine (20) has an inflow region (21) and an outflow region (22) and a working medium flows through said turbine during operation. The working medium flows into the inflow region (21), along a front side (23a) formed on the impeller (23) and subsequently out of the outflow region (22). There is a pressure drop at the front side (23a) between the inflow region (21) and the outflow region (22). A pressure distributer (9) is arranged on the rear side (23b) of the impeller (23), opposite the front side (23a). The pressure distributer (9) comprises a slide ring (31), which cooperates with the rear side (23b) of the impeller (23) and thereby forms a vapour-lubricated throttle. A first flow path (51) runs through the throttle, wherein the throttle hydraulically divides the rear side (23b) into a first region (231) and a second region (232). The first region (231) borders the inflow region (21), and the second region borders a pressure chamber (11). During operation, the inflow region (21) is applied with a higher pressure than the pressure chamber (11). The slide ring (31) is axially moveable. A sealing ring (33) arranged in a groove (41) cooperates with the slide ring (31). A second flow path (52) runs from the inflow region (21) to the pressure chamber (11) between the groove (41) and the slide ring (31). The second flow path (52) can be closed by the sealing ring (33). The sealing ring (33) can be moved in the groove (41) in a defined manner.
