The ejector is a plunger on the bolt face actuated by a coil spring. There were three large central bogies, sprung by a vertical coil spring. Suspension was Horstmann coil spring on bogies. The air forks were switched out in favor of Showa coil spring forks. Front suspension is usually double wishbone with coil spring struts. A coilover consists of a damper with a coil spring encircling it. Lancia Flaminia with 'suicide' door and coil spring suspension. It offered three- and five-door configurations, increased size and a torsion beam/coil spring rear suspension. The torsion bars were replaced with a coil spring setup. The firing pin is operated by a plastic hammer under pressure from a coil spring. Four of the bogies were on bellcranks in pairs, with a common horizontal coil spring. This design consists simply of a coil spring with two handles. Traditionally, a grease-lubricated steel coil spring is used as the powerplant main spring. Under tension or compression, the material (wire) of a coil spring undergoes torsion. A steel coil spring stores impact energy from landing and then releases it.
