A latching solenoid () includes a coil () and an armature (). The armature () moves between latch position and a rest position in response to momentary energization of the coil () without moving in response to de-energization of the coil (). A solenoid controller () is operable to receive messages from a vehicle bus () and output control signals that cause energization of the coil ().

Bus configured latching solenoid

A three position fast acting solenoid which may be coupled to a spool valve with a center null position. The spool of the valve is moved to one of three positions by a momentary signal to either of two coils. The spool is held positively in each end position by magnetism, and in the center position by a mechanical stop, so that the valve requires no electrical input except when the valve is changing from one position to another.

Three position fast acting solenoid

A number of variations may include a product comprising a latching solenoid comprising: a valve; a spring operatively connected to the valve; a base plate adjacent the valve, wherein the base plate is constructed and arranged to maintain residual magnetism; an armature adjacent the baseplate and operatively connected to the spring; a pin disposed within the armature and operatively connected to the valve; wherein the latching solenoid includes a coil, wherein when the latching solenoid is energized the coil pulls the armature in a first direction toward the base plate; and wherein when the latching solenoid is energized the base plate becomes residually 15 magnetized so that when the armature moves in the first direction toward the base plate the armature magnetically latches to the base plate and remains attached to the base plate when the latching solenoid is de-energized.

Latching solenoid for engine management

A number of variations may include a product including a thermal management component comprising a housing comprising a first polymer wherein the first polymer is constructed and arranged to provide thermal control of at least one neighbor component comprising an exterior surface in contact with the thermal management component wherein the first polymer comprises a heat generating polymer.

Thermal management system and method of making and using the same

A solenoid is latched in an energized position by a residual magnetic field established by a pulse of current. A degaussing current is selectively applied from a capacitor to unlatch the solenoid. Fail-safe return to the de-energized position occurs when the supply of power is lost.

A drive system () for a vehicle includes an electric motor () and a gas turbine assembly (). The electric motor () includes a rotor () coupled to a drive shaft (). The gas turbine assembly () includes a turbine () including a turbine wheel () mounted on the drive shaft (), a burner () that burns fuel and provides exhaust gas to drive the turbine wheel (), and a compressor () that provides compressed air to the burner (). The gas turbine assembly () is coupled to the drive shaft () of the electric motor (). The drive system () also includes gear train unit () that has the drive shaft () as an input shaft, has an output shaft () connected to vehicle wheels (), and transmits power from one of the electric motor () or gas turbine assembly () to the wheels ().

A torque pulsated variable cam timing camshaft arrangement for a reciprocating piston, internal combustion engine is provided. The arrangement includes a sprocket. A torque pulsated phaser unit is operatively associated with the sprocket. A camshaft is operatively associated with the sprocket and the camshaft torsionally powers the phaser unit. The camshaft has a cam lobe engaged with a first cam follower for controlling a position of a spring biased valve. A spring biased second cam follower is engaged with the cam lobe providing a torsional input to the camshaft.

Additional spring and follower mechanism built into valve cover or bearing bridge

Power transmission chains () which are suitable for automotive uses as well as other uses and which have a reduced susceptibility to wear and corrosion, in which such chains () are constructed to include a plurality of sets () of links () joined at overlapped ends () thereof by a pivot () including at least one ceramic joint component (), such as a pivot means (). Such chains () also include means () to drivingly engage sprocket teeth () of a sprocket drive ().

Power transmission chain with ceramic joint components

A drive system for an internal combustion engine including an endless chain connecting a drive sprocket on a crankshaft to a driven sprocket on a camshaft. The drive system is comprised of at least one balance shaft and a torsion bar. The balance shaft has a first end for connection to the drive sprocket and a center bore. The torsion bar is located within the center bore of the balance shaft. The torsion bar has a first end for connection to the drive sprocket and a second end fixedly attached to the inner end of the center bore. The torsion bar absorbs torsional vibrations and isolates torsional vibrations due to inertia of the balance shaft caused by the crankshaft. Bearings are located between the first end of the torsion bar and the center bore of the balance shaft, to center the torsion bar within the balance shaft.

Torsional damper for balance shafts

A VCT phaser having a mechanical feedback in which no elaborate sensors and its concomitant electronic control loop is required. The phaser has center mounted spool valve controlling the flow of control fluid such that when a command positions the same at a predetermined position, passages within the phaser adjusts to a desired position through the mechanical feedback.

Control mechanism for cam phaser

In a variable cam timing (VCT) system that has a crank shaft coupled to at least one cam shaft. The system has at least one timing gear associated with the crank shaft or a cam shaft. The timing gear includes at least two groups of toothlike projections including a first group having a first distance to the center of the wheel, and a second group having a second distance to the center of the wheel. The first distance is different from the second distance. Whereby torsional energy for torque actuated purposes is increased for the VCT system. The system may further include a resonator which is positioned upon the at least one cam shaft, the resonator including at least one mass and at least one elastic element. Whereby torsional oscillation of the at least one cam shaft at a predetermined engine speed range is increased.

A chain and sprocket system includes a plurality of chains and phased or offset sprockets. Problems related to equalizing or sharing the load between the driven sprockets in a multiple axis, phased system are eliminated by providing sprockets that rotate independently of one another and having only one of those sprockets transmit load or power to the driven shaft.

Sprocket for multiple axis phased chain systems

The present invention relates to a torsionally compliant sprocket assembly which reduces the transfer of the crankshaft torsional oscillations to other components in the engine such as the balance shaft drives. The assembly comprises a first sprocket, second sprocket and a planar torsion spring located between the two sprockets and the shaft.

Torsionally compliant sprocket system for balance shaft drive

The present invention relates to a torsionally compliant sprocket system which absorbs crankshaft torsional vibrations and minimizes their transfer to other components in the engine system. In particular, the present system interposes resilient spring members between a crankshaft sprocket and an adjacent balance shaft drive sprocket which are interconnected. A damping mechanism provides damping of the system to reduce resonant oscillations.
