Beschreibung
Zusammenfassung:	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 first pump actuator, a second fluid flow source featuring a second pump actuator, a first shuttle valve arranged between the first pump actuator and the second pump actuator, a first clutch and a second clutch that are fluidically connected to the first shuttle valve so that the first clutch and the second clutch can respectively be fluidically controlled via the first pump actuator or the second pump actuator, a third clutch configured to be fluidically controlled at least via the first pump actuator, and a fourth clutch configured to be fluidically controlled at least via the second pump actuator.
