Abstract
A pump device for a motor vehicle, includes a pump device housing; a delivery chamber which is formed in the pump device housing and/or at least partially by the pump device housing and which includes an inlet and an outlet; a delivery structure which is arranged in the delivery chamber and delivers a fluid from the inlet on a low-pressure side of the pump device to the outlet on a high-pressure side of the pump device; a first conduit which channels the fluid from the outlet out of the delivery chamber to a first assembly; wherein a second conduit diverges from the first conduit in the region before the first assembly and feeds a portion of the pressurised fluid to a second assembly.
Claims16
A pump device for a motor vehicle, comprising:
- a pump device housing;
- a delivery chamber which is formed in the pump device housing and/or at least partially by the pump device housing and which comprises an inlet and an outlet;
- a delivery structure which is arranged in the delivery chamber and delivers a fluid from the inlet on a low-pressure side of the pump device to the outlet on a high-pressure side of the pump device;
- and
- a first conduit which channels the fluid from the outlet out of the delivery chamber to a first assembly;
- wherein a second conduit diverges from the first conduit in the region before the first assembly and feeds a portion of the pressurised fluid to a second assembly, and
- wherein a filter element is arranged at a point where the second conduit diverges from the first conduit.
A pump device for a motor vehicle, comprising:
- a pump device housing;
- a delivery chamber which is formed in the pump device housing and/or at least partially by the pump device housing and which comprises an inlet and an outlet;
- a delivery structure which is arranged in the delivery chamber and delivers a fluid from the inlet on a low-pressure side of the pump device to the outlet on a high-pressure side of the pump device;
- and
- a first conduit which channels the fluid from the outlet out of the delivery chamber to a first assembly;
- wherein a second conduit diverges from the first conduit in the region before the first assembly and feeds a portion of the pressurised fluid to a second assembly,
- wherein a filter element is arranged in a region or at a point where the second conduit diverges from the first conduit, and
- wherein the filter element protrudes at least partially into the first conduit.
A pump device for a motor vehicle, comprising:
- a pump device housing;
- a delivery chamber which is formed in the pump device housing and/or at least partially by the pump device housing and which comprises an inlet and an outlet;
- a delivery structure which is arranged in the delivery chamber and delivers a fluid from the inlet on a low-pressure side of the pump device to the outlet on a high-pressure side of the pump device;
- and
- a first conduit which channels the fluid from the outlet out of the delivery chamber to a first assembly;
- wherein a second conduit diverges from the first conduit in the region before the first assembly and feeds a portion of the pressurised fluid to a second assembly,
- wherein a filter element is arranged in a region or at a point where the second conduit diverges from the first conduit, and
- wherein the filter element arranged so as to be self-cleaning, such that pollutants in the fluid which are prevented by the filter element from flowing into the second conduit are flushed away from the filter element by the fluid in the first conduit and are carried off towards the first assembly.
A pump device for a motor vehicle, comprising:
- a pump device housing;
- a delivery chamber which is formed in the pump device housing and/or at least partially by the pump device housing and which comprises an inlet and an outlet;
- a delivery structure which is arranged in the delivery chamber and delivers a fluid from the inlet on a low-pressure side of the pump device to the outlet on a high-pressure side of the pump device;
- and
- a first conduit which channels the fluid from the outlet out of the delivery chamber to a first assembly;
- wherein a second conduit diverges from the first conduit in the region before the first assembly and feeds a portion of the pressurised fluid to a second assembly,
- wherein the first assembly is a filter which cleans the fluid, fed from the outlet via the first conduit, by filtering it, and
- wherein a filter element is arranged in the region or at a point where the second conduit diverges from the first conduit.
