Solenoid

1. An elecromechanical device similar in operation to a relay, however, the movement of the armature or iron core results in changing electrical energy into mechanical energy. 2. An electro-mechanical device used to effect a push-pull mechanical operation using electrical current. 3. A rely with an external mechanical movement.

Solenoid Relay

A relay that connects a solenoid to an electrical circuit, such as a starter-motor solenoid relay.

Solenoid Switch

An electrical switch that is opened and closed mechanically by the movement of a solenoid core.

Solenoid Valve

A mechanical valve that is operated by a solenoid to control the flow of a liquid or a gas. Used in braking systems, air conditioning systems, emission control systems, cruise control systems and even suspension and steering systems.

Solid Axle

A term used for beam axle or rigid axle.

Solid Oxide

1. A solid combination of oxygen and zirconium that serves as an electrolyte for a fuel cell.

Solid Pushrod

A pushrod made from solid stock.

Solid Rotor

A rotor that is a solid piece of metal with a friction surface on each side.

Solid State Device

Any device that can control current without moving parts, heated filaments, or vacuum gaps. Thus, all semiconductors are solid-state devices but some solid-state devices are not semiconductors ( for example, transformers).

Solid State Ignition

An ignition system using diodes and transistors to control spark timing.

Solid State Regulator

An alternator regulator having no moving parts.

Solid Valve Lifter

A term used for mechanical valve lifter.

Solid Wire

A single stranded conductor, usually insulated.

Solid-axle Suspension

Suspension system in which the wheels are mounted at each end of a solid, or undivided, axle or axle housing.

Solid-state Device

An electronic component constructed from any type of semiconductor material.

Solids

1. A type of paint pigment. 2. A solid or mechanical valve lifter.

Solidus

The highest temperature at which a metal or an alloy is completely solid.

Solo

1. By oneself. 2. A run made by a single car during a drag-race elimination.

Soluble

A substance that will dissolve in a solvent.

Solvent

1. A liquid substance, such as water, in which other substances can dissolve. 2. A petrochemical liquid that will dissolve oil and grease. 3. A paint cleaner and thinner.
