Control device for a hydraulic clutch a direct coupling of a hydraulic torque converter

摘要

The control device dc includes a selector valve 59 rise to a first fluid pipe 85, 79, 89, 92, 88 for feeding fluid under pressure of the hydraulic clutch a direct coupling cd from a source of fluid under pressure, 50, and on a second fluid duct 86, derivation on the first between the clutch, cd and the selector valve 59. In its two positions of end, the latter opens the first fluid pipe, it closes in a third position, intermediate. The second fluid duct 86 is closed in the two positions of end of the selector valve 59 and open in the third position of that - latter, in order to allow the exhaust of fluid to a reservoir 58. A restriction 96 is a rise in the first line, between the junction of the two pipes and the selector valve 59. / p & & p & application to automobile, 2004.
