  • One-piece spring and poppet incorporated into a valve seat assembly and associated method for manufacturing a one-piece spring and poppet
    Patent number: 7721756
    Abstract: A combined spring and poppet assembly incorporated into a valve housing which communicates with a fluid inlet and outlet. The integral assembly includes an elongated and three dimensional shaped, resilient body positioned in linearly displaceable fashion within the valve housing, and along a path established between the fluid inlet and outlet. The body includes a forward-most disposed poppet which seats against the fluid inlet in a normally flow disrupting fashion. The body further includes an integrally formed spring biasing portion. Upon a pressure in the fluid inlet exceeding a predetermined value, the poppet being caused to unseat from the inlet and to displace linearly against the spring portion, concurrent with fluid flow being established across the outlet.
