Title: Quick opening solenoid valve
Inventor: LEWIS STEPHEN R
IPC: F16K31/06
Filed: 1999-07-26
Abstract: PROBLEM TO BE SOLVED: To retain a spool with respect to a valve seat by utilizing a solenoid. SOLUTION: A spool 109 slides within a bore and opens and closes a valve 101. An armature 165 movable with respect to the spool is biased in a first direction. A coupled biasing member biases the armature and the spool toward each other. When the solenoid 169 is actuated, the armature and the spool move in a second direction opposite to the first direction, and the spool is tightly engaged with a valve seat 113 within the bore. Thus, the valve is closed and the spool stops moving. Thereafter, the armature continues to move in the second direction and the coupled biasing member further applies force to the spool. Thus, the spool is held in engagement with the valve seat, and the armature reaches a second position at which the armature is tightly engaged with the spool. Accordingly, the armature stops further moving in the second direction.  However, the standing-still armature continues to apply pressure to the spool to thereby hold the spool in engagement with the valve seat. When the voltage of the solenoid is cut off, the armature moves back in the first direction by the biasing force of the armature until the armature abuts against the spool. Thus, the spool is quickly moved away from the valve seat and the valve is opened.
