However, due to their size, the utility pump provides a volumetric flow and / or pressure that is too large and / or too high for one or more common supply supply cycles, so that a portion of the fluid is lost to be discharged to storage for the fluid in the device

Embodiment Construction
[0113] figure 1 A fluid supply system of a first exemplary embodiment is shown. The fluid supply system comprises a first pump 1 which supplies a first fluid consumer 3 with fluid in a first supply circuit 5 . The fluid consumer 3 can be, for example, an internal combustion engine for driving a motor vehicle. The fluid can in particular be lubricating oil, and the supply circuit 5 can accordingly be a lubricating oil circuit for supplying the fluid consumer 3 with lubricating oil. Furthermore, the fluid can also be used to cool the fluid consumer 3 , eg a piston of the fluid consumer 3 if the fluid consumer 3 is embodied as an internal combustion engine. The pump 1 is designed to deliver fluid in the first circuit 5 with at least a first volume flow V1 and at least a first supply pressure P1. The volume flow V1 and the supply pressure P1 can be, for example, the volume flow and the supply pressure in the main oil gallery of the internal combustion engine. The pump 1 can be...

A fluid supply system supplying multiple fluid consumers of a vehicle with fluid, the fluid supply system including: (a) a first pump 1 supplying a first fluid consumer 3, arranged in a first supply circulation 5 of the vehicle, with fluid; (b) a second pump 2 supplying a second fluid consumer 4, arranged in a second supply circulation 6 of the vehicle, with fluid; and (c) a directional control valve 7,8;15,8 adjustable between a first valve position and at least one other, second valve position and preferably includes an electromagnetic device 7b,15b for adjusting; (d) the directional control valve allows the fluid to be delivered from the second pump into the first supply circulation in the first valve position and separates the first supply circulation from the second pump, or allows the fluid to be delivered from the second pump into the first supply circulation 5 only to a restricted extent as compared to the first valve position, in the second valve position.
Description
technical field [0001] The invention relates to a fluid supply system for supplying fluid to a plurality of fluid consumers of a motor vehicle. Background technique [0002] A vehicle including an internal combustion engine may include a lubricating oil circuit for lubricating the engine with lubricating oil and a cooling circuit for cooling the engine (eg, for cooling pistons of the engine). Often, one of these loops branches off from the other. For internal combustion engines with variable valve control timing, a supply supply cycle for adjusting the phase position of the camshaft relative to the crankshaft is also provided. Additionally or alternatively, the drive motor may also have the option of adjusting the length of the linkage, and the vehicle may include a supply supply circuit for adjusting the linkage. Furthermore, one or more supply circuits are generally provided for supplying one or more transmissions, for example automatic transmissions and / or steering tran...
