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".
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]
Poppet valves are typically opened by the camshaft lobe or rocker arm, and closed by a coiled spring called a valve spring. Valve float occurs when the valve spring is unable to control the inertia of the valvetrain at high engine speeds (RPM). [4] [5]
An overhead valve engine, abbreviated (OHV) and sometimes called a pushrod engine, is a piston engine whose valves are located in the cylinder head above the combustion chamber. This contrasts with flathead (or "sidevalve") engines , where the valves were located below the combustion chamber in the engine block .
A back-pressure regulator, back-pressure valve, pressure sustaining valve or pressure sustaining regulator is a control valve that maintains the set pressure at its inlet side by opening to allow flow when the inlet pressure exceeds the set value.
1. input airflow; 2. output airflow; 3. valve tubing; 4. valve casing; 5. internal rotor; 6. valve ports, or "knuckles"; 7. rotor spindle. A rotary valve (also called rotary-motion valve) is a type of valve in which the rotation of a passage or passages in a transverse plug regulates the flow of liquid or gas through the attached pipes.

There are also dual-flush toilets that use a siphon valve operated by a lever rather than buttons, with a ≤ 6L full flush, and a ≤ 3L half-flush if the flush handle is held down [8] or released immediately after flushing. [9] Tipping bucket. The tipping bucket cistern can operate in a dual flush mode when the lever is rotated halfway 2.5/5 ...
Diaphragm valves can be controlled by various types of actuators e.g. manual, pneumatic, hydraulic, electric etc. The most common diaphragm valves use pneumatic actuators; in this type of valve, air pressure is applied through a pilot valve into the actuator which in turn raises the diaphragm and opens the valve. This type of valve is one of ...
