Abstract
A solenoid having a controlled rate of motion is provided. The solenoid includes a housing having a channel disposed therein, a coil disposed around the channel for providing an electromagnetic force in response to a current being supplied therethrough, and a plunger disposed within the channel and movable between a first position and a second position in response to the presence or absence of the electromagnetic force. A dampener is linked to the plunger which creates an atmospheric pressure differential as the plunger moves to one or both of the first position or the second position which pressure differential acts to slow the rate of movement of the plunger.
