Accelerated flow Type of flow that takes place in nozzles.The flow accelerates and pressure reduces. Air pump A reciprocating or centrifugal pump used to remove air, and sometimes the condensace from the condenser of a steam plant. Angle of advance The angle in excess of 90 degrees by which the eccentric throw of a steam engine valve gear is in advance of the crank. Allan Valve A steam engine slide valve in which a supplementary passage increases the steam supply to the port during admission to reduce wire drawing. Atmospheric engine An early form of steam engine in which a partial vacuum created by steam condensation allowed atmospheric pressure to drive down the piston.

Absolute motion Motion of a body in relation to some other body which is at rest. Acceleration Rate of change of velocity with respect to time, of a particle which is in motion.It is vector quantity. Addendum The radial distance from the pitch circle to the top of the tooth. Angular acceleration The time rate of change of angular velocity. Angular velocity The time rate of change of angular displacement of a point rotating about a fixed axis.Angular velocity of a machine part is often expressed in revolutions per minute. Arc of contact The arc traced out along the pitch circle while one pair of teeth of gear wheels is in contact . BEVEL GEARING – Gearing arrangement in which the axes of the shafts connected by gears intersect. CAM – A reciprocating, oscillating or rotating body which imparts reciprocating or oscillating motion to a second body, called the FOLLOWER with which it is in contact.  CAM PROFILE – The surface profile of the cam t...
