SYSTEM AND METHOD FOR THE TRANSFER OF FLUID IN A VEHICLE

摘要

A system for the transfer of fluid in a vehicle includes a main tank (4), a secondary tank (5), a pump (6), a first valve arrangement (11) and a several fluid pathways (13, 15, 17). In response to a control signal, the system is placed into a first condition, in which the first valve arrangement (11) is in a first condition, in which the pump (6) transfers the fluid from the secondary tank (5) to the main tank (4) through the valve arrangement (11), or into a second condition, in which the first valve arrangement (11) is in a second condition and the fluid pathways are blown clean from fluid. Also, a method for transfer of fluid in a system intended for a vehicle is disclosed.

主权项

1. A system for the transfer of fluid in a vehicle, wherein the system comprises:
a main tank for fluid; a secondary tank for the fluid; a pump; a first valve arrangement; a connection to a source of pressurized air; a first fluid pathway that connects the source of pressurized air with the first valve arrangement; a second fluid pathway that connects the first valve arrangement and the secondary tank; a third fluid pathway that connects the first valve arrangement and the main tank, wherein the pump is arranged at least partially in the first and the third fluid pathways; andwherein the system is configured so that as a response to a control signal, the system is placed into a first condition, in which the first valve arrangement is in a first condition in which air under pressure flows through the first fluid pathway from the source of pressurized air to the pump, the pump being configured to transfer the fluid from the secondary tank to the main tank through the first valve arrangement and through the second and third fluid pathways, or the system is in a second condition, in which the first valve arrangement is in a second condition in which air under pressure flows through the first and second fluid pathways from the source of pressurized air through the valve arrangement to the secondary tank, the pump being configured to transfer a flow of air in the third fluid pathway from the first valve arrangement to the main tank.
