A system for a motor vehicle may include a reservoir, a plurality of lubricant paths extending through the reservoir, a plurality of coolant paths extending through the reservoir, a plurality of delivery devices attached to the reservoir, and a plurality of coolers attached to the reservoir. The reservoir may include two sumps for lubricant. The reservoir may include (i) a plurality of reservoir lubricant inlet connections and a plurality of reservoir lubricant outlet connections through which the lubricant paths extend, (ii) a plurality of reservoir coolant inlet connections and a plurality of reservoir coolant outlet connections through which the coolant paths extend, (iii) a plurality of fluidic pump connections fluidically connected to the plurality of delivery devices, and (iv) a plurality of reservoir lubricant outlets, a plurality of reservoir lubricant inlets, a plurality of reservoir coolant outlets, and a plurality of reservoir coolant inlets fluidically connected to the coolers.

A filter device may include a filter housing cup, a filter head, and a ring filter element arranged in the filter housing cup. The ring filter element may include an upper end plate on which at least two radially outward projecting bayonet wings are arranged which interact with a plurality of recesses disposed in the filter housing cup. The plurality of recesses may respectively define an undercut contour and a first end position of an associated bayonet wing guided therein. At least two driving elements may be arranged on the upper end plate. At least two ramps and two stops may be arranged on the filter head such that, when fitting the filter device, the at least two driving elements slide on the at least two ramps to the two stops and press the at least two bayonet wings into the undercut contour of an associated recess.

Filter device

A fluid supply system with a component includes a first bypass valve arranged in a control channel with a valve body adjustable at least between a first and a second position. The valve body separates the control channel into a first and a second space and has a leakage opening connecting the first space to the second space. The second space is connected to a fluid reservoir via a leakage channel, and a switchable valve is arranged in the leakage channel. A sensing device is configured to sense a property of the fluid and convey the property to a controlling device that is configured to close the valve to block the leakage channel when a predefined property is reached. A second bypass valve is configured to reduce a transient oscillation of the first bypass valve during a starting of the system.
