Abstract: Actuator arrangement for a drive train. The actuator arrangement has an actuator pump driven by electric motor, and a clutch actuator, which is designed for actuation of a friction clutch of the drive train and which is connected to a discharge port of the actuator pump. The actuator arrangement has a parking lock actuator, which is designed for actuation of a parking lock arrangement of the drive train. The parking lock actuator has an open position, in which the parking lock arrangement is released, and a closed position, in which the parking lock arrangement is closed. The parking lock actuator is likewise connected to the discharge port of the actuator pump. The parking lock arrangement can be retained in at least one of the open position and the closed position by means of a retaining device.
