It is a perforated metal conical strainer with much larger holes than a chinois. A China cap is used to remove seeds and other coarse matter from soft foods, but produces a coarser-textured product than the chinois. [5] Both the chinois and the China cap often are used with a cone-shaped pestle. With the pestle tip placed in the bottom of the ...
When describing a crankshaft design, the number of main bearings is generally quoted, as the number of crank pins is determined by the cylinder layout. For example, the Toyota VZ V6 engine is described as having a "four bearing crankshaft" and the Jaguar XK6 straight-six engine has a "seven bearing crankshaft".
Fengshanche (Chinese: 風扇車 [1]; pinyin: fēngshànchē; lit. 'wind fan vehicle') was a winnowing machine that was used in ancient China to separate the grain from the chaff or seed casings after harvest. The winnowing machine also had a rotary fan which had a blower that had a crank handle to create air to blow away the lighter seed ...
The crankshaft is a rotating shaft containing one or more crankpins, [1] that are driven by the pistons via the connecting rods. [2] The crankpins are also called rod bearing journals, and they rotate within the "big end" of the connecting rods. Most modern crankshafts are located in the engine block.
The crankcase often forms the upper half of the main bearing journals (with the bearing caps forming the other half), although in some engines the crankcase completely surrounds the main bearing journals. An open-crank engine has no crankcase. This design was used in early engines and remains in use in some large marine diesel engines.
[2] On slow-moving delivery vehicles and boats, there was often no suitable air slipstream for the road draught tube. In these situations, the engines used positive pressure at the breather tube to push blow-by gases from the crankcase. Therefore, the breather air intake was often located in the airflow behind the engine's cooling fan. [1]
The duplex strainer system usually consists of two separate strainer baskets housings. The system also contains a valve handle placed between the two baskets to divert the flow of liquid to one strainer while the other is being cleaned. On some strainers, the valve will work automatically and the strainer will perform a self-cleaning operation.
A cover, which fits around the outside bowl, contains a spinning mechanism which causes the inside strainer to rotate rapidly. [10] There are a number of different mechanisms used to operate the device, including the use of a crank handle, push button or pull-cord. [12] Crank or handle This is the original design, and still very popular.
