Anti-pollution device, characterized by the arrangement of a valve having a valve body, a valve chamber therein, an inlet to the chamber that provides a seat for a valve member within the chamber, an outlet from the chamber, and a spherical valve member of elastomeric material within the chamber between the inlet and the outlet, which is adapted to engage the seat, in order to close the inlet; a means within the chamber, which normally holds the spherical valve member against the seat to close the inlet, the valve member being elastically deformable, under the fluid pressure from the inlet, to clear the seat for the passage of said fluid .
