Abstract
A poppet valve device is proposed, comprising a valve stem, a poppet, having a sealing surface and being formed separately from the valve stem, wherein the poppet is actuatable via the valve stem, and wherein, following an imaginary line parallel to a longitudinal direction of the valve stem along the closing direction of the poppet, the sealing surface is passed before a front end of the valve stem is passed.
Claims29
A poppet valve device comprising
- a valve stem,
- a poppet, having a sealing surface and being formed separately from the valve stem, and
- a reset unit for resetting the poppet into an initial position,
- wherein the poppet is actuatable via the valve stem,
- wherein, following an imaginary line parallel to a longitudinal direction of the valve stem along a closing direction of the poppet, the sealing surface is passed before a front end of the valve stem is passed,
- wherein the sealing surface is on a side of the poppet facing away from the valve stem,
- wherein the reset unit is embodied as a reset spring that is supported at the poppet, and
- wherein the reset spring is supported on the side of the poppet, which also comprises the sealing surface or the reset unit is arranged opposite the valve stem in relation to the poppet.
