Patent ID: 8240444

Claim:
A control device for a gearbox comprising: a pressure medium source ( 2 ); a pressure-limiting device ( 8 ) connected to the pressure medium source ( 2 ) downstream therefrom; at least one first controllable valve device ( 15 ) connected to the pressure-limiting device ( 8 ) downstream therefrom, and at least one actuating device ( 29 ) connected to the first controllable valve device ( 15 ) downstream therefrom for adjusting the gearbox; at least one second controllable valve device ( 35 ), which is directly connected, via a supply line ( 7 ), to the pressure medium source ( 2 ), and at least one further actuating device ( 47 ) connected to the second controllable valve device ( 35 ) downstream therefrom; an electric control device ( 14 ) for actuating the first and second controllable valve device ( 15 , 35 ); a sensor device ( 54 ) connected to the electric control device ( 14 ) for measuring a pressure of pressure medium in the supply line ( 7 ); the electric control device ( 14 ) being actively connected to the second controllable valve device ( 35 ) such that the second controllable valve device ( 35 ) and the further actuating device ( 47 ) are controllable as a function of a measurement of the pressure of the pressure medium in the supply line ( 7 ) generated by the sensor device ( 54 ).
