摘要:
It is disclosed a poppet valve (2) with a valve body (4) which has a cavity (6), a coolant inlet port (8), and a coolant outlet port (10); wherein the coolant inlet port (8) and the coolant outlet port (10) are arranged on a valve stem (12) of the poppet valve (2), wherein the cavity (6) extends into the valve stem (12) of the poppet valve (2) and into a valve head (14) of the poppet valve (2), wherein there is provided a coolant conducting element (16) within the cavity (6) and extending into the cavity (6) from the valve head (14) to the valve stem (12), where the coolant conducting element (16) in each case has a cross-section, wherein the coolant conducting element (16) includes a pipe section ( 18) and a funnel section (20), wherein the coolant conducting element (16) extends concentrically to the poppet valve (2) in the cavity (6) of the poppet valve (2).
