Patent ID: 7146901

Claim:
A hydraulic system, in which pressure medium from a pressure medium reservoir ( 2 ) is delivered by a pressure medium source ( 1 ) to at least one consumer ( 10 , 12 , 13 , 14 ) with a piston space ( 7 ) and at least two pressure medium delivery lines ( 6 , 8 ), such that when the at least one consumer ( 10 , 12 , 13 , 14 ) is in a non-actuated condition a first pressure medium delivery line ( 8 ) is connected to the pressure medium reservoir ( 2 ) and a second pressure medium delivery line ( 6 ) is connected to the pressure medium source ( 1 ), when the at least one consumer ( 10 , 12 , 13 , 14 ) is in an actuated condition, the first and second pressure medium delivery lines ( 6 , 8 ) are both connected to the pressure medium source ( 1 ) and the pressure level in the first and second pressure medium delivery lines ( 6 , 8 ) is the same.
