Replaceable fluid container
A replaceable fluid container for a vehicle, the container comprising: a housing comprising a fluid reservoir; an outlet port arranged on the housing to couple the reservoir in fluidic communication with a fluid system of the vehicle for supplying fluid from the reservoir to the vehicle; an inlet port arranged on the housing to couple the reservoir for receiving fluid from the engine to the reservoir; and a vent port arranged on the housing to couple the reservoir for allowing gas to be passed into and out from the reservoir, wherein the inlet, outlet and vent ports are arranged on a common end of the housing and are arranged such that the distance between the vent port and the nearest of the inlet port and outlet port is greater than the distance between the inlet port and the outlet port.
1. A replaceable fluid container for a vehicle, the container comprising:
a housing comprising a fluid reservoir and a coupling mechanism;
an outlet port arranged on the coupling mechanism to couple the reservoir in fluidic communication with a fluid system of the vehicle for supplying fluid from the reservoir to the vehicle;
an inlet port arranged on the coupling mechanism to couple the reservoir in fluidic communication with the fluid system of the vehicle for receiving fluid from the vehicle to the reservoir; and
a vent port arranged on the coupling mechanism to couple the reservoir in fluidic communication with the vehicle for allowing gas to be passed into and out from the reservoir,
wherein the inlet, outlet and vent ports are arranged on a common end of the coupling mechanism and are arranged such that the distance between the vent port and the nearest of the inlet port and outlet port is greater than the distance between the inlet port and the outlet port, and
wherein the coupling mechanism is arranged such that the container is connected to couple the reservoir in fluidic communication with the fluid system by relative movement between the container and the vehicle that is in a rotational direction.
2. A container as claimed in claim 1 in which the inlet port, the outlet port and the vent port are arranged in a linear radial alignment on the end of the coupling mechanism.
3. A container as claimed in claim 1 in which the inlet port, outlet port and vent port are arranged on the end of the coupling mechanism in a non-linear radial alignment such that the radial distance between the vent port and the nearest of the inlet port and outlet port is greater than the radial distance between the inlet port and the outlet port.
4. A container as claimed in claim 3 in which the vent port is arranged radially outermost of the inlet port, outlet port and vent port.
5. A container as claimed in claim 1 in which at least one sealing or separating member is provided around at least one of the ports or between at least two of the ports.
6. A container as claimed in claim 1 in which the coupling mechanism is arranged such that the container is connected to couple the reservoir in fluidic communication with the fluid system by relative movement between the container and the vehicle that is in a rotational direction through an angle of less than 360 degrees.
7. A container as claimed in claim 1 in which the reservoir contains a fluid.
8. A container as claimed in claim 7 in which the fluid is an engine lubricating oil composition or a heat exchange fluid for an electric engine.
9. An apparatus comprising a container as claimed in claim 1 in fluidic communication with a fluid system of a vehicle through the inlet port and outlet port and in fluidic communication with the vehicle through the vent port.
10. An apparatus as claimed in claim 9 in which the container is in fluidic communication with a fluid system of a vehicle engine through the inlet port and outlet port and in fluidic communication with the vehicle engine through the vent port.
