solids
Glossary “solids” Definition:
1). A type of paint pigment. 2). A solid or mechanical valve lifter.
solidus
Glossary “solidus” Definition:
Highest temperature at which a metal or an alloy is completely solid.
solid state regulator
Glossary “solid state regulator” Definition:
An alternator regulator having no moving parts.
solid valve lifter
Glossary “solid valve lifter” Definition:
Term used for mechanical valve lifter.
solid wire
Glossary “solid wire” Definition:
Single stranded conductor, usually insulated.
solid pushrod
Glossary “solid pushrod” Definition:
Pushrod made from solid stock.
solid rotor
Glossary “solid rotor” Definition:
Rotor that is a solid piece of metal with a friction surface on each side.
solid state device
Glossary “solid state device” Definition:
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
Glossary “solid state ignition” Definition:
Ignition system using diodes and transistors to control spark timing.
solid oxide
Glossary “solid oxide” Definition:
A solid combination of oxygen and zirconium that serves as an electrolyte for a fuel cell.
solid axle suspension
Glossary “solid axle suspension” Definition:
Suspension system in which the wheels are mounted at each end of a solid, or undivided, axle or axle housing.
solid lifter
Glossary “solid lifter” Definition:
Valve lifter or tappet that is one piece, and usually made of cast iron. Solid lifters cannot compensate for wear so the valve clearance must be checked and adjusted at regular intervals.
solenoid switch
Glossary “solenoid switch” Definition:
Electrical switch that is opened and closed mechanically by the movement of a solenoid core.
solenoid valve
Glossary “solenoid valve” Definition:
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.
solenoid vent valve
Glossary “solenoid vent valve” Definition:
Carburetor vent valve that is engerized by the ignition switch to control fuel vapor flow to the carbon canister. With the ignition off, the valve is open.
solid axle
Glossary “solid axle” Definition:
Term used for beam axle or rigid axle.
