Abstract
A turbocharger system includes a wastegate with a bypass passage and a valve assembly. The valve assembly includes a poppet with an axis. The valve assembly also includes an arm that is attached to the poppet and that supports movement of the poppet between a closed position and an open position. Additionally, the valve assembly includes a plurality of biasing members that are disposed within a joint between the poppet and the arm. The plurality of biasing members provides a biasing force directed in a radial direction relative to the axis. The plurality of biasing members is disposed substantially symmetrically with respect to a first radial line of symmetry and a second radial line of symmetry.
