FIELD: transport.SUBSTANCE: lubricant is forced to transmission running gears and clutch increased-friction discs. Clutch discs are engaged by said lubricant under pressure. Valve assembly with slide valve responds to clutch pressure to release portion of said lubricant from clutch discs into lower crankcase and transmission to remove dirt accumulated in clutch discs. Said slide valve is arranged to make lubricant flow only at valve intermediate displacement to minimize whatever pressure drop in transmission and clutch.EFFECT: higher reliability.19 cl, 5 dwg |
