Abstract
A valve assembly is disclosed for controlling fluid flow between two reservoirs. The valve assembly includes a relief valve arranged inside the housing and configured to open a first fluid flow path when the first reservoir is above a first predetermined pressure value.
Claims20
A valve assembly configured for controlling fluid flow between a first reservoir and a second reservoir, the valve assembly comprising:
- a valve housing;
- a relief valve arranged inside the valve housing and configured to open a first fluid flow path inside the valve housing when a pressure inside the first reservoir is above a first predetermined pressure value;
- and
- a solenoid assembly arranged inside the valve housing and configured to open a second fluid flow path inside the valve housing when a rate of the fluid flow from the first reservoir to the second reservoir is above a predetermined reference value.
1 more element
An evaporative emissions control system for a vehicle having a first reservoir and a controller, the emissions control system comprising:
- a second reservoir;
- and
- a valve assembly configured to regulate fluid flow between the first reservoir and the second reservoir, wherein each reservoir is arranged externally with respect to the valve assembly, the valve assembly including:
- a valve housing;
- a relief valve arranged inside the valve housing and configured to open a first fluid flow path inside the valve housing in response to the controller when a pressure inside the first reservoir is above a first predetermined pressure value;
- and
- a solenoid assembly regulated by the controller, arranged inside the valve housing, and configured to open a second fluid flow path inside the valve housing in response to the controller when a rate of the fluid flow from the first reservoir to the second reservoir is above a predetermined reference value.
