Abstract
The present invention provides for a solenoid valve assembly including a housing () defining a cavity (). A support () is disposed in the cavity and defines a bore (). A coil () is disposed about the support and defines an energized state for generating a magnetic field and a de-energized state. A plunger () is movably disposed in the bore of the support between a first position engaging the housing and a second position spaced from the housing. The plunger is radially spaced from the support to define a gap () between the plunger and the support. A dampener () is coupled to one of the support and the plunger adjacent the gap to prevent direct engagement between the support and the plunger as the plunger moves between the first and second positions during the energized and de-energized states for reducing noise during operation.
