1. A solenoid-actuated valve assembly with reduced noise, comprising:
- a manifold having first, second, third and fourth stepped bores formed therein;
a longitudinally extending solenoid-actuated valve disposed within said stepped bores;
a support bracket secured to the manifold adjacent said first stepped bore;
a rubber retainer disposed between the support bracket and valve for cushioning longitudinal vibrations of the valve for noise reduction; and
first, second and third rubber gaskets disposed about said valve and cushioning said valve with respect to said second, third and fourth bores, respectively, for cushioning lateral vibrations of the valve for noise reduction.

Abstract
A solenoid-actuated valve assembly is provided with reduced noise. A rubber retainer and steel retainer secure the valve within a manifold, and the rubber retainer absorbs longitudinal vibrations. A plurality of rubber gaskets surround the body of the valve and prevent metal-to-metal contact between the valve body and the manifold for cushioning lateral vibrations of the valve. The valve is substantially submerged in transmission fluid for airborne noise abatement, and opposing ends of the valve body are provided in communication with a vent port for substantially pressure-balancing the valve body.

7. A solenoid-actuated valve assembly with reduced noise, comprising:
-
a manifold having a plurality of stepped bores formed therein in communication with each other, said manifold including a cavity formed therein in communication with the bores and including transmission fluid in the cavity, said transmission fluid including floating particles; a longitudinally extending solenoid-actuated valve disposed within stepped bores, said valve comprising an armature and a non-magnetic sleeve substantially surrounding the armature for preventing said floating particles from attaching to the armature; a support bracket secured to the manifold adjacent said stepped bores; a rubber retainer disposed between the support bracket and valve for cushioning longitudinal vibrations of the valve for noise reduction; and a plurality of rubber gaskets disposed about said valve and abutting the sidewalls of said plurality of bores for cushioning lateral vibrations of the valve for noise reduction. - View Dependent Claims (8, 9, 10)

11. A solenoid-actuated valve assembly with reduced noise, comprising:
-
a manifold having first, second, third and fourth stepped bores formed therein in communication with each other, said manifold further including a cavity formed therein in communication with the bores and including transmission fluid in the cavity, said transmission fluid including floating particles; a longitudinally extending solenoid-actuated valve disposed within said stepped bores, said valve comprising an armature and a non-magnetic sleeve substantially surrounding the armature for preventing said floating particles from attaching to the armature; a support bracket secured to the manifold adjacent said stepped bores; a rubber retainer disposed between the support bracket and valve for cushioning longitudinal vibrations of the valve for noise reduction; a plurality of rubber gaskets disposed about said valve and abutting the sidewalls of said bores for cushioning lateral vibrations of the valve for noise reduction; and wherein said valve is substantially submerged in said transmission fluid for airborne noise abatement. - View Dependent Claims (12, 13)
