A pressure control for a fuel supply device to supply fuel from a reservoir to a user includes at least two flow paths between a high-pressure chamber and a low-pressure chamber, and an operable closure unit for opening and closing of the at least two flow paths.

Poppet valve

A poppet valve is provided with a seat portion which has a conical inner peripheral surface with a center axis, and a conical portion which is displaced along the center axis inside the seat portion, forms a flow passage having an annular cross-section between the conical portion and the seat portion and is supported at a position concentric with the seat portion. An effect of rectifying fluid flowing in the flow passage is thereby obtained and the generation of noise is prevented.
