ABSTRACT:
A solenoid for selectively actuating a valve. The solenoid has a housing removably connected in a fluid-tight manner to a housing of the valve. An actuating coil is housed within the solenoid housing with an actuating plunger coaxial therewith internally thereof. The plunger is actuated reciprocably to a projected position for opening the valve when the actuating coil is energized and restores to a restored position when the coil is deenergized. The plunger terminates in a push pin of lesser diameter and defines a shoulder therewith and an opposite end terminates in an axial shaft or axle shaft of lesser diameter which defines a second shoulder therewith. Flexible dampeners are mounted on both shoulders for dampening the plunger movement as it reaches two extreme positions corresponding to the projected and restored positions thereof. The dampeners engage portions of the solenoid housing to dampen the plunger arrival at its terminal or extreme positions.
