Device for activation of hydraulic switching cylinders, particularly for switching gears of dual-clutch gearbox of motor vehicle, has regulating valve and rotary slide valve downstream regulating valve

摘要

The device has a regulating valve (15) and a rotary slide valve (16) downstream the regulating valve by which switching pressure on the piston chamber of the switching cylinders (1,2,3,4) is switched. The piston chamber is impinged with pressure. The regulating valve is designed as pilot-controlled or directly-controlled 3 by 2 directional control valve. The rotary slide valve is fluidically connected with two sides of the piston chamber from each switching cylinder by a duct. The sides of pistons (17,18,19,20) are impinged with pressure during activation of the duct to a switching cylinder.
