Two aggregates connection shifting controlling device, has pressurized surface, permanently pressurized with pressurizing medium at inlet, designed as diameter stage of main slide valve and provided in groove area communicating with inlet

摘要

The device has a pilot control valve, and a shifting device with a pressurized surface permanently pressurized with a pressurizing medium, which is present at an inlet (22). The shifting device produces a force in opposite direction to a force exerted on a main slide valve (26) by a shifting piston (63). The surface is designed as a diameter stage (82) of the valve and provided in an area of a groove (22a) that communicates with the inlet.
