In the present study, numerical simulations of the flow in a three-dimensional axisymmetric poppet valve are conducted using a vortex method. The fluids are assumed inviscid and incompressible. The vibration of the poppet, supported by a spring and a dash pot, occurs in the axial direction in some range of parameters. The numerical simulations are carried out by varying systematically the parameters of the calculation, namely the supply pressure, the spring constant, the mass of the poppet and the conical angle of the poppet. The process of jet flow development, the fluctuations of the valve lift and the velocity distributions in the valve are investigated for the poppet vibrating.
