Patent ID: 8578800

Claim:
A hydraulic control arrangement for an automated shift transmission, particularly a dual clutch transmission for a motor vehicle, with a lubricating cooling system ( 80 ) including and a main lubricant pump ( 51 ) and a controllable additional pump ( 56 ) which together ensure an oil supply of the hydraulic control arrangement ( 50 ), the lubricating cooling system ( 80 ) comprising a lubricating pressure slide (RS SmD) for adjusting a lubricating pressure in the lubricating cooling system ( 80 ), and the controllable additional pump ( 56 ) being connected to a pressure control channel ( 102 ) of the lubricating pressure slide (RS SmD) for providing a lubricating fluid control pressure, the lubricating pressure slide (RS SmD) being designed in such a manner that the adjusted lubricating pressure increases with increasing lubricating control pressure, with a lower limit of the lubricating fluid pressure being fixed by a spring ( 81 ), the lubricating cooling system ( 80 ) including a extending from the main lubricant pump ( 51 ) to the lubricating pressure slide (RS SmD) for supplying an oil volume flow from the main lubricant pump ( 51 ) to the lubricating cooling system ( 80 ) and an additional oil channel ( 103 ), via which an additional oil volume flow can be conducted from the controllable additional pump ( 56 ) to the lubricating cooling system ( 80 ), the pressure control channel ( 102 ) of the lubricating pressure slide (RS SmD) extending through at least part of the additional oil channel ( 103 ).
