Intake arrangement
View Patent ↗Intake arrangement for an internal combustion engine for the intake of a liquid medium from a container, having a strainer, via which liquid medium can be taken in from the container, and at least one suction pipe which opens with a first end into the strainer and via which the liquid medium can be delivered towards a suction pump, which interacts with the respective suction pipe. The suction pipe is mounted at a second end that faces away from the strainer such that it can be pivoted about an axis such that the suction pipe follows a movement of the liquid within the container.
1. A suction arrangement for an internal combustion engine configured to draw in a liquid medium from a tank, comprising:
a suction basket from which the liquid medium can be drawn in from the tank;
a first suction pipe having a first end and a second end, the first end opening into the suction basket and via which the liquid medium is delivered in a direction of a first suction pump, and the second end being arranged at a position opposite the suction basket; and
a second suction pipe having a first end and a second end, the first end opening into the suction basket and via which the liquid medium is delivered in a direction of a second suction pump, and the second end being arranged at a position opposite the suction basket,
wherein the second end of the first suction pipe and the second end of the second suction pipe are each pivotably mounted about a common axis such that the first suction pipe, the second suction pipe, and the suction basket follow a movement of the liquid medium within the tank initiated by a movement of the tank, and
wherein the respective second ends of the first and second suction pipes are deflected in opposite directions such that longitudinal axes of each the respective second ends are on the common axis.
2. The suction arrangement according to claim 1 , wherein the first and second suction pipes are substantially parallel to one another.
3. The suction arrangement according to claim 1 , wherein the first and second suction pipes are one selected from the group of:
(i) connected to one another, and
(ii) an integral part of a monolithic suction pipe assembly.
4. The suction arrangement according to claim 1 , further comprising:
stops configured to delimit a pivot movement of the first suction pipe, the second suction pipe, and the suction basket.
5. The suction arrangement according to claim 4 , wherein the stops define an angular range of maximally 150° for the pivot movement.
6. The suction arrangement according to claim 1 , wherein the suction basket comprises a sieve.
7. The suction arrangement according to claim 1 , further comprising
non-return valves assigned to the first suction pipe and the second suction pipe and configured to prevent a return flow of the liquid medium from the first and second suction pipes into the tank when a respective one or more of the first and second suction pumps is stationary.
8. The suction arrangement according to claim 1 , further comprising:
a filling level sensor in a region of the first end of at least one of the first and second suction pipes adjacent to the suction basket.
9. The suction arrangement according to claim 1 , wherein the suction basket is made of a relatively heavy, metallic material, and the first and second suction pipes are made of a relatively light material.
