A solenoid assembly includes a solenoid adapted to be coupled to a solenoid connecting member extending from a support member. The solenoid assembly also includes a retaining bracket having a body portion and a securing portion. The body portion is adapted to be removably coupled to the support member. The securing portion is removably coupled to the solenoid. The retaining bracket is moveable between an unsecured position, and a secured position. The securing portion of the retaining bracket provides a spring force to the solenoid when the retaining bracket is in the secured position such that the solenoid is biased toward the solenoid connecting member to secure the solenoid between the solenoid connecting member and the securing portion of said retaining bracket.

Hydraulic control module and solenoid assembly included therein

A switch valve assembly controls first and second fluid flows in a hydraulic circuit defined by a valve body and a separator plate of a valve body assembly of a hydraulic control module. The valve body defines a fluid exit. The valve body is further defined as first and second body housings. The switch valve assembly includes a piston moveable between a first position for allowing the first fluid flow to flow and a second position for allowing the first and second fluid flows to flow into the fluid exit, and a biasing member coupled to the piston and biasing the piston from the second position toward the first position. The piston presents a regulating surface oriented with respect to the first axis. The first fluid flow fluidly engages the regulating surface in a manner that biases the piston into the first position in conjunction with the biasing member.

A solenoid assembly includes a solenoid adapted to be coupled to a solenoid connecting member, with the solenoid connecting member extending from a support member. The solenoid assembly also includes a retaining bracket having a body portion and a securing portion extending from the body portion. The body portion is adapted to be removably coupled to the solenoid connecting member, and the securing portion is removably coupled to the solenoid. The retaining bracket is moveable between an unsecured position, and a secured position. The securing portion of the retaining bracket provides a spring force to the solenoid when the retaining bracket is in the secured position such that the solenoid is biased toward the solenoid connecting member to secure the solenoid between the solenoid connecting member and the securing portion of the retaining bracket.

A pulse width modulated solenoid system having low noise characteristics is described. Noise reduction is primarily achieved by separating the solenoid device from the insulator and the manifold housing through the use of rubber isolators and multiple sets of o-rings, thus preventing metal to metal contact. Additional noise reduction is achieved by encapsulating all of the solenoids, using the insulator, the cover plate, the housing, and the screen carrier. Noise levels are also further reduced by minimizing the impact force of the armature against the sleeve by allowing fluid to vent into the upper area of the sleeve, thus causing a dampening effect.

Pulse width modulated solenoid

A solenoid control valve is described wherein the valve employs a precision molded plastic valve seat member, a corresponding control valve body which includes flying buttresses for supporting and distributing loads on the control valve body, and armature vent features.

On/off solenoid

A control module for a vehicle transmission. The control module includes an electronic transmission control unit attached to a cooling plate. Control solenoids are attached to the cooling plate. The cooling plate is operably secured over a &ldquo;worm trail&rdquo; manifold in a transmission for controlling the transmission.

Electro-hydraulic module for automatic transmission control

A solenoid control valve ( ) that includes an electromagnetic coil ( ) positioned within a housing ( ) and a spool valve ( ) positioned within a central bore ( ) of a valve body ( ). An armature ( ), including a pin element ( ) and a check ball ( ), is axially positioned within the coil ( ) and an armature spring ( ) biases the check ball ( ) against an opening in the central bore ( ) when the coil ( ) is not energized. The spool valve ( ) includes an internal chamber and a pair of sealing lands ( ) that selectively seal a supply port ( ) and a control port ( ) within the valve body ( ). A pole piece ( ), including an annular flux shunt portion ( ), is threadably engaged with the housing ( ) to control a working air gap ( ) between the pole piece ( ) and the armature ( ). The flux shunt portion ( ) more radially directs the electromagnetic field lines to weaken the magnetic force as the armature ( ) moves closer to the pole piece ( ). A flux tube ( ) is positioned within the housing ( ).
