2. Solenoid valve - Wikipedia

   en.wikipedia.org/wiki/Solenoid_valve

   Non-magnetic core tubes are used to isolate the fluid from the coil. The core tube encloses the plugnut, the core spring, and the core. The coil slips over the core tube; a retaining clip engages the depression near the closed end of the core tube and holds the coil on the core tube. Solenoid valve designs have many variations and challenges.

3. Solenoid - Wikipedia

   en.wikipedia.org/wiki/Solenoid

   Of course, if the solenoid is constructed as a wire spiral (as often done in practice), then it emanates an outside field the same way as a single wire, due to the current flowing overall down the length of the solenoid. How Ampère's law can be applied to the solenoid. Applying Ampère's circuital law to the solenoid (see figure on the right ...

4. Solenoid (engineering) - Wikipedia

   en.wikipedia.org/wiki/Solenoid_(engineering)

   The term "solenoid" also often refers to a solenoid valve, an integrated device containing an electromechanical solenoid which actuates either a pneumatic or hydraulic valve, or a solenoid switch, a specific type of relay that uses an internal electromechanical solenoid to operate an electrical switch; for example, an automobile starter ...

5. Variable force solenoid - Wikipedia

   en.wikipedia.org/wiki/Variable_force_solenoid

   A variable force solenoid (VFS) is an electro-hydraulic device that controls pressure proportionally or inversely proportionally to a signal (voltage or current) obtained from the on-board controller of a powertrain. A low flow VFS is used as a signal level devices for transmission line pressure control or application of clutches.

6. Solenoid voltmeter - Wikipedia

   en.wikipedia.org/wiki/Solenoid_voltmeter

   A solenoid voltmeter is a specific type of voltmeter electricians use to test electrical power circuits. [1] It uses a solenoid coil to attract a spring-loaded plunger; the movement of the plunger is calibrated in terms of approximate voltage. It is more rugged than a D'arsonval movement, but neither as sensitive nor as precise.

7. Starter solenoid - Wikipedia

   en.wikipedia.org/wiki/Starter_solenoid

   The starter motor is a series, compound, or permanent magnet type electric motor with a solenoid and solenoid operated switch mounted on it. When low-current power from the starting battery is applied to the starter solenoid, usually through a key-operated switch, the solenoid closes high-current contacts for the starter motor and it starts to ...

8. Wig wag (washing machines) - Wikipedia

   en.wikipedia.org/wiki/Wig_wag_(washing_machines)

   When a solenoid is de-energized, the pin drops due to gravity. One of the wig-wag's solenoids is turned on to engage agitation during wash mode; the other solenoid is turned on to engage the spin-dry mode. The motor must be turned on before the solenoids are powered. Only one solenoid may be operated at a time.

9. Flyback diode - Wikipedia

   en.wikipedia.org/wiki/Flyback_diode

   In Figure 2, a flyback diode was added in antiparallel with the solenoid. Instead of spiking to -300 V, the flyback diode only allows approximately -1.4 V of potential to be built up (-1.4 V is a combination of the forward bias of the 1N4007 diode (1.1 V) and the foot of wiring separating the diode and the solenoid [dubious – discuss]). The ...
