Abstract: Fluid filter arrangement for a motor vehicle drive train. The filter arrangement comprises a filter housing, which has a fluid inlet and a fluid outlet, allowing fluid to flow in one flow direction from the fluid inlet to the fluid outlet. A filter insert is arranged in the filter housing and divides an interior of the filter housing into an inlet region connected to the fluid inlet and an outlet region connected to the fluid outlet. The filter insert has a filter medium for filtering fluid. The filter insert has a perforated plate having a plurality of holes. The holes are arranged ahead of the filter medium in the flow direction. The size of at least some of the holes is adapted so that fluid impinges upon the filter medium at an increased flow velocity.

Abstract: A fluid supply device for a transmission of a motor vehicle. The fluid supply device comprises at least one fluid supply device housing. At least one pump and at least one electric motor are integrated in the fluid supply device housing. The fluid supply device is configured in a modular fashion.

Abstract: Nozzle arrangement for fluid applications, in particular for a hydraulic circuit of a motor vehicle drive train. A nozzle body has a first longitudinal end and a second longitudinal end. The nozzle body has a first longitudinal section having a cylindrical outer circumference, which has a first outside diameter. The nozzle body has a blind hole starting from the first longitudinal end. In the region of the second longitudinal end, the nozzle body has a second longitudinal section having a second outside diameter, which is smaller than the first outside diameter. A third longitudinal section is formed between the first longitudinal section and the second longitudinal section. A substantially radially aligned nozzle bore connects the outer circumference of the third longitudinal section to the blind hole.

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.
