A thermostatic radiator valve on position 2 (15–17 °C) Installed thermostatic radiator valve with the adjustment wheel removed A thermostatic radiator valve (TRV) is a self-regulating valve fitted to hot water heating system radiator, to control the temperature of a room by changing the flow of hot water to the radiator.
A dry valve acts as an air vent until a dribble of water passes through it and swells the cartridge. If the valve dries out again, it re-opens. A characteristic of these valves is that they function best on the hot delivery side of a radiator and may not open as vents unless the water supply is hot. [8]
For water-cooled engines on aircraft and surface vehicles, waste heat is transferred from a closed loop of water pumped through the engine to the surrounding atmosphere by a radiator. Water has a higher heat capacity than air, and can thus move heat more quickly away from the engine, but a radiator and pumping system add weight, complexity, and ...
Bleed screw key Bleed screw key in use at a domestic radiator. On a home radiator unit, the bleed screw can be opened, usually by means of a key, to allow unwanted air to escape from the unit. Bleed screws are also found on some pump types fulfilling a similar purpose. They are most often located at the top of the radiator on the side of the ...
In this arrangement the inlet cooling to the engine is controlled by double-valve thermostat which mixes a re-circulating sensing flow with the radiator cooling flow. These employ a single capsule, but have two valve discs. Thus a very compact, and simple but effective, control function is achieved.
Daimler 22 hp [10] open 2-seater (1909 example). The clearly visible mascot on its radiator cap is (C. Y.'s) Knight A replicated 1912 Stearns advertisement in downtown Boise, Idaho touting the Knight-type motor. In 1901 Knight bought an air-cooled, single-cylinder three-wheeler whose noisy valves annoyed him.
The RB engine is an oversquare 2.0–3.0 L straight-6 four-stroke gasoline engine from Nissan, originally produced from 1985 to 2004.The RB followed the 1983 VG-series V6 engines to offer a full, modern range in both straight or V layouts. [3]
The Ford Sidevalve is a side valve (flathead engine) from the British arm of the Ford Motor Company, often also referred to as the "English Sidevalve".The engine had its origins in the 1930s Ford Model Y, and was made in two sizes, 933 cc (56.9 cu in) or "8 HP", and 1,172 cc (71.5 cu in) or "10 HP".
