Expansion Valve Types
- An expansion valve is a slide valve used in a steam engine to control the cut-off. It rides on the back of an adapted main slide valve and is driven by an additional eccentric that has more advance than the main eccentric. The cut-off is adjusted in one of two ways.
- Device which restricts flow of high pressure refrigerant thus lowering refrigerant pressure.
- A refrigerant-metering valve with a pressure or temperature controlled orifice.
- (type) a subdivision of a particular kind of thing; "what type of sculpture do you prefer?"
- A person, thing, or event considered as a representative of such a category
- (type) write by means of a keyboard with types; "type the acceptance letter, please"
- A person of a specified character or nature
- (type) character: a person of a specified kind (usually with many eccentricities); "a real character"; "a strange character"; "a friendly eccentric"; "the capable type"; "a mental case"
- A category of people or things having common characteristics
Stanley Steamer
Early Stanley cars had light wooden bodies mounted on tubular steel frames by means of full-elliptic springs. Steam was generated in a vertical fire-tube boiler, mounted beneath the seat, with a vaporizing gasoline (later, kerosene) burner underneath. The boiler was reinforced by several layers of piano wire wound around it, which gave it a strong, yet relatively light-weight, shell. In early models, the vertical fire-tubes were made of copper, and were expanded into holes in the upper and lower crown sheets. In later models, the installation of a condenser caused oil-fouling of the expansion joints, and welded steel fire-tubes were used instead. The boilers were safer than one might expect – they were fitted with safety valves, and even if these failed, a dangerous overpressure would rupture one of the many joints long before the boiler shell was in danger of bursting, and the resulting leak would relieve the boiler pressure and douse the burner with little risk to the occupants of the car. There has never been a documented case of a Stanley boiler exploding in use.[
Kew Bridge engines
This Hathorn and Davey triple expansion inverted steam engine is one of the noisiest at Kew Bridge engines thanks to its Corliss drop valve type gear which operates with a loud clicking . The engine is so economical on steam that it is left running continuously unlike the other engines, which are run at specific times to save steam). It is by far the most modern engine design represented at the museum.
