Many small engines, such as those found in mopeds or garden machinery, are single cylinder and use only a single piston, simplifying crankshaft design.

This is remedied by the use of a small piston or diaphragm pump which, when actuated by the throttle linkage, forces a small amount of gasoline through a jet into the carburetor throat.

However, they are not as responsive and efficient as small piston engines over the wide range of RPMs and powers needed in vehicle applications.

Turbines have historically been more expensive to produce than piston engines, though this is partly because piston engines have been mass-produced in huge quantities for decades, while small gas turbine engines are rarities ; however, turbines are mass-produced in the closely related form of the turbocharger.

In some engines, the small end is offset to reduce thrust in the intended rotational direction and the forward face of the piston has been made thinner and lighter to compensate-but when running backwards, this weaker forward face suffers increased mechanical stress it was not designed to resist.

Cocking the gun causes the piston assembly to compress the spring until a small hook on the rear of the piston engages the sear ; pulling the trigger releases the sear and allows the spring to decompress, pushing the piston forward, thereby compressing the air in the chamber directly behind the pellet.

A small fossil fuelled piston engine sized for average power use charges the accumulator.

Papin describes first pouring a small quantity of water into the bottom of a vertical cylinder, inserting a piston on a rod and after first evacuating the air below the piston, placing a fire beneath the cylinder in order to boil the water away and create enough steam pressure to raise the piston to the top end of the cylinder.

The header tank supplied cold water under pressure via a stand-pipe for condensing the steam in the cylinder with a small branch supplying the cylinder-sealing water ; at each top stroke of the piston excess warm sealing water overflowed down two pipes, one to the in-house well and the other to feed the boiler by gravity.

Solenoid-controlled valves are often used in irrigation systems, where a relatively weak solenoid opens and closes a small pilot valve, which in turn activates the main valve by applying fluid pressure to a piston or diaphragm that is mechanically coupled to the main valve.

" Suffice it to say that mushroom valves, springs and cams, and many small parts, are swept away bodily, that we have an almost perfectly spherical explosion chamber, and a cast-iron sleeve or tube as that portion of the combustion chamber in which the piston travels.

A garlic press is a kitchen utensil to crush garlic cloves efficiently by forcing them through a grid of small holes, usually with some type of piston.

Magnetos were used on the small engine's ancestor, the stationary " hit and miss " engine which was used in the early twentieth century, on older gasoline or distillate farm tractors before battery starting and lighting became common, and on aircraft piston engines.

Brakes were either small 4-wheel discs with twin-piston calipers ( only available on the JDM 2. 0-Si model ), larger 4-wheel discs with single piston calipers, or a front disc / rear drum system.

When the barrel recoiled, the piston was pulled back by the barrel's recoil and thus pushed the oil through a small orifice and into a second cylinder placed underneath.

The response trigger ( rt ) uses a small pneumatic piston to create automatic fire and runs off excess blow-back gasses.

He used the blanket for late morning naps when hosts of the night had gone off to jobs and proved reluctant to leave him in their small rooms with their few possessions.

Lautner, for his part, `` belonged to the present-day race of small artists, who do not demand the utmost of themselves '', and the bitter description of the type includes such epithets as `` wretched little poseurs '', the devastating indictment `` they do not know how to be wretched decently and in order '', and the somewhat extreme prophecy, so far not fulfilled: `` They will be destroyed ''.

And if I have gone into so much detail about so small a work, that is because it is also so typical a work, representing the germinal form of a conflict which remains essential in Mann's writing: the crude sketch of Piepsam contains, in its critical, destructive and self-destructive tendencies, much that is enlarged and illuminated in the figures of, for instance, Naphta and Leverkuhn.

Even the officer in charge, be it a captain ( for small display ) or a general, is restrained by monitoring.

The double editorial on Two Aspects Of `` The U.S. Spirit '' was subtly calculated to suggest a moral sanction for gambles great as well as small, reflecting popular approval of this questionable attitude toward the highest office in the land.
