摘要:
A fluid injection valve comprising: a valve body including a first end having a first opening, a second end having a second opening, an outer surface and an inner surface defining a fluid pathway extending between the first end and the second end; a seat arranged along the fluid pathway; a restriction device selectively abutting the seat; a biasing member arranged in the fluid pathway abutting the restriction device; urging the restriction device against the seat; a biasing element having a biasing force urging the biasing member against the restriction device; and a magnet functionally connected to the biasing element, the magnet selectively forcing the biasing member axially outwardly of the restriction device against the biasing force.
