Is there a one-way valve at Buick Hideo fuel filler?

Yes This one-way valve is actually very simple, and most one-way valve structures will not cause too much interference to the oil pumping of the intubation.

In order to prevent the gasoline from leaking from the fuel filler when the vehicle is overturned or tilted, a one-way valve will be designed at the joint between the fuel pipe and the fuel tank, which ensures that the gasoline can enter the fuel tank from the fuel pipe, but the gasoline in the fuel tank cannot flow back to the fuel pipe.

non-return valve

Used in hydraulic system to prevent oil flow from flowing backwards, or used in pneumatic system to prevent compressed air from flowing backwards. There are two kinds of check valves: straight-through type and right-angle type. Straight-through check valves are installed on threaded pipes. Right-angle check valves have three forms: threaded connection, plate connection and flange connection.

Hydraulic control one-way valve, also known as locking valve or pressure maintaining valve, is the same as one-way valve to prevent oil from flowing back. However, when the oil flow needs to flow in the reverse direction in the hydraulic circuit, the one-way valve can be opened by controlling the oil pressure to make the oil flow in both directions. Hydraulic control one-way valve adopts conical valve core, which has good sealing performance.
