摘要： A solenoid valve includes an outlet tube and a plunger stop. A plunger is slidably disposed within the solenoid valve between the outlet tube and the plunger stop. The plunger is movable between a closed position wherein the plunger engages the outlet tube to block fluid flow through an outlet passage formed in the outlet tube and an open position wherein the plunger is distanced from the outlet tube to permit fluid flow through the outlet passage. The solenoid valve also includes a coil that is energizable to bias the plunger between the closed position and the open position. The plunger stop is configured so that the magnitude of the force of attraction between the plunger and the plunger stop is linearly proportional to the magnitude of the current applied to the coil. Moreover, the magnitude of the force of attraction between the plunger and the plunger stop is independent of the position of the plunger.
