A poppet valve comprising a ball supported within an axial bushing, the ball being urged onto the valve seat by an operating element and being lifted off the valve seat by the force of a spring, wherein pressure is applied to the ball surface within the valve seat, is characterized in that the end of the bushing facing the valve seat protrudes in tangential direction beyond the periphery or equator of the ball and defines together with the ball surface in this region a space for fluid flow inversion to thereby further improving the lifting aid achieved by the bushing with respect to a further decrease of the switching delay together with an increase of the flow rate while maintaining the same flow losses as prior art poppet valves with such bushing.
