ABSTRACT:
A solenoid operated, direct acting, poppet style two-way valve wherein the fluid pressures on the valve member are completely balanced, a low power electrical signal is required to control its opening and the design features are such as to permit a valve of minimum size and which can be manufactured at a minimum cost. The valve housing and valve member are each manufactured from tubing, each with one end formed radially inwardly by a spinning process to provide a valve seat and valve seat engaging surface respectively. The valve member has a through passage and the end remote from the valve seat engaging end slides on a fixed piston having a cross-sectional area equal to the area of the valve seat such that the valve member is in complete axial pressure balance. The valve member includes a support member and an elongated flexible stem extending therefrom on the free end of which the valve seat engaging surface is located whereby the valve seat can be self-aligning with its valve seat.
