An armature assembly is provided for use in a solenoid actuator assembly having an energizable coil. The solenoid actuator assembly includes a housing and a bore disposed in the housing. The armature assembly has an outer surface and is positioned in the bore for axial sliding movement. The armature assembly has an outer surface which is of a diameter significantly less than a diameter of the bore and defines a fluid passage through the bore. Sleeve bearings are positioned at preselected spaced locations within the bore and extends about and in contact with a shaft of the armature assembly.

[ I claim:] [1.] A solenoid actuator assembly having an energizable coil, comprising:a housing having first and second ends, first, second and third bores disposed in said housing, each of said bores in communication with one another, each of said bores having a preselected diameter, and a longitudinal axis, said energizable coil being connected to said housing;an armature assembly having first and second ends, a longitudinal axis, a shaft, and an outer surface having a preselected diameter, said armature assembly being disposed in and axially movable in said third bore in opposed directions along the longitudinal axis of said housing, said armature outer surface being substantially smaller in diameter than the diameter of the third bore, the length of the armature measured axially between the armature first end and the armature second end being smaller than the length of the third bore, thereby defining concentric fluid passages around said shaft and armature, such that during movement of the armature assembly, fluid passes through the bores and around the armature and shaft; andfirst and second sleeve bearings disposed within the bore, extending about and in contact with the armature assembly and the housing, and positioned at preselected spaced locations on said armature assembly.
