(swords) and a toothed wheel. This engages a second shaft known as the tappet shaft or wiper shaft whose job is to lower the treadles and throw the shuttle...

device called a dobby. Dobbies can produce more complex fabric designs than tappet looms but are limited in comparison to Jacquard looms. Dobby looms first...

also known as tappet shedding, is the control of the movement of heald shafts in weaving simple constructions by means of cams or tappets. In positive...

design used, the valves are actuated by a rocker arm, finger, or bucket tappet. Overhead valve engines use rocker arms, which are actuated from below indirectly...

between the cams and rocker arms. It is relatively easy to use roller tappets in conventional valvetrains, although it does add considerable moving mass...

drive shaft, in contrast to the axial piston pump. The stroke of each piston is caused by an eccentric drive shaft or an external eccentric tappet (e.g...

rev-counter, RPM gauge) is an instrument measuring the rotation speed of a shaft or disk, as in a motor or other machine. The device usually displays the...

camshaft is usually transferred to the valves either directly (using a tappet) or indirectly via a rocker arm. A dual overhead cam, double overhead cam...

distributor shaft is driven by a gear on the camshaft, often shared with the oil pump; on most overhead camshaft engines, the distributor shaft is attached...

of inlet valve. The intake valve opening mechanism incorporates a valve tappet and a piston inside a chamber. There is a solenoid valve controlled by the...

double overhead camshafts (DOHC) operating directly on shim and bucket tappets. In 1980 the first major upgrading of the 750cc and 1000cc machines with...

piston and cylinder, similar to a small pneumatic ram. The tappet bore where a hydraulic tappet would normally reside becomes the cylinder, and the retainer...

variable-geometry guide vanes charge air side with compressor wheel Turbo shaft bearings Turbo shaft bearings The rotating-vane VGT was first developed under Garrett...

optimizing the valve duration avoids undue stresses to the camshaft lobes and tappets. 'Valve bounce' is a related condition where the valve does not stay seated...

are fastened to a shaft, all in a row. This requires multiple shafts; it cannot be done on a single-shaft loom. The different shafts (also called harnesses)...

Hydraulic tappet Multi-valve Overhead camshaft Overhead valve Pneumatic valve springs Poppet valve Pushrod Rocker arm Sleeve valve Tappet Timing belt...

by applying various simplifications. One method is to assume the spokes, shaft and hub have zero moments of inertia, and the flywheel's moment of inertia...

ECU of an engine. The sensor is usually located on the butterfly spindle/shaft, so that it can directly monitor the position of the throttle. More advanced...

In both cases the machinery was operated by cams on the shaft of a waterwheel or on a tappet wheel, which lifted the hammer. Driving stocks were pivoted...
