Hydraulic circuit for a hybrid drivetrain

A hydraulic circuit for a hybrid drive train for changing driving operation states of a hybrid-operated vehicle, comprising:

• a first fluid flow source including a reversible first pump actuator;
• a second fluid flow source featuring a reversible second pump actuator;
• a first shuttle valve arranged between the reversible first pump actuator and the reversible second pump actuator;
• a first actuation device and a second actuation device that are fluidically connected to the first shuttle valve so that the first actuation device and the second actuation device can respectively be fluidically controlled via the reversible first pump actuator or the reversible second pump actuator;
• a third actuation device configured to be fluidically controlled at least via the reversible first pump actuator;
• and
• a fourth actuation device configured to be fluidically controlled at least via the reversible second pump actuator.
