ABSTRACT:
A poppet valve assembly and method of making same are provided and such assembly comprises a housing; a flow passage in the housing with the passage having a central axis and being adapted to flow a fluid in either direction therethrough; a poppet structure for controlling flow through the passage; a support structure for supporting the poppet structure during movement thereof along the axes; an actuator contact on the poppet structure between its head and stem to enable movement of the poppet structure along the axes; and apparatus for engaging the contact to provide the movement wherein the support structure comprises a cylindrical inside surface provided on the housing and having an axial length generally of the order of several times the particular diameter, and the support structure also comprises a cylindrical outside surface on the stem which slideably engages the inside surface, with the inside and outside surfaces cooperating and defining sole means confining the poppet structure against movements transverse the axes during movement of the poppet structure along the axes.
