Abstract
A pressure adjuster may connect with a supply path connecting a fuel supply device and a fuel use device. The pressure adjuster may comprise a pressure chamber communicating with the supply path located closer to the fuel supply device than a check valve of the supply path, a communication chamber communicating with the supply path located closer to the fuel use device than the check valve, a valve member including a first pressure-receiving surface and switching between an open state and a closed state by pressure of fuel inside of the pressure chamber at the first pressure-receiving surface, a discharge path communicating with the communication chamber and configured to discharge fuel flowing from the communication chamber to outside of the casing when the valve member is in the open state, and a constriction portion disposed in the discharge path and constricting a cross section area of the discharge path.
