Crank and Connecting Rod Objective To obtain the displacement diagram for the piston of a crank and connecting rod assembly Theory The slider crank chain is one of the two basic mechanisms which from the basic for many more complicated motions. (The others are the four Bar Chain‚ Scoth Yoke or Chebyshev linkage of which over 800 forms are known). It transforms linear motion to circular motion or vice versa. A crank is an arm attached at right angles to a rotating shaft by which reciprocating

the chamber and opens when the oil is pushed into the cylinder. At this point the suction ball within the chamber is forced shut and oil pressure builds in the cylinder. In a bottle jack the piston is vertical and directly supports a bearing pad that contacts the object being lifted. With a single action piston the lift is somewhat less than twice the collapsed height of the jack‚ making it suitable only for vehicles with a relatively high clearance. For lifting structures such as houses the hydraulic

Piston Engines Picture a tube or cylinder that holds a snugly fitting plug. The plug is free to move back and forth within this tube‚ pushed by pressure from hot gases. A rod is mounted to the moving plug; it connects to a crankshaft‚ causing this shaft to rotate rapidly. A propeller sits at the end of this shaft‚ spinning within the air. Here‚ in outline‚ is the piston engine‚ which powered all airplanes until the advent of jet engines. Pistons in cylinders first saw use in steam engines. Scotland’s

CRAFT HYDRAULIC SYSTEM INTRODUCTION Hydraulics is based on a very simple fact of nature - you cannot compress a liquid. You can compress a gas (think about putting more and more air into a tire‚ the more you put in‚ the higher the pressure). If you’re really strong you can compress a solid mass as well. But no matter how much pressure you apply onto a liquid‚ it isn’t possible to compress it. Now if you put that liquid into a sealed system and push on it at one end‚ that pressure is transmitted

generated steam‚ which drove the piston in the open top cylinder above the boiler. When the steam built up‚ the pressure opened a value allowing the steam to fill the cylinder and push the piston up. When the piston reached the top of the cylinder‚ the first valve was closed and the second valve opened. This second valve sprayed cold water into the cylinder from a cistern‚ condensing the steam and creating a vacuum. The air pressure from the open-top cylinder pushed the piston down again‚ thus pulling the

to push the piston for turning the engine when starting. In this 2-stroke engine‚ the air intake and exhaust are taken into the engine cylinder liner through scavenging ports and exhaust ports. The cylinder head covers the top of the cylinder and houses the starting air valve‚ fuel valve or injector. It will also contain a relief valve and indicator cock. The piston contains piston rings that will seal the high pressure combustion gases from the bottom part of the engine. The piston is cooled by

Compressed-air engine is a pneumatic actuator that creates useful work by expanding compressed air. They have existed in many forms over the past two centuries‚ ranging in size from hand held turbines up to several hundred horsepower. Some types rely on pistons and cylinders‚ others use turbines. Many compressed air engines improve their performance by heating the incoming air‚ or the engine itself. Some took this a stage further and burned fuel in the cylinder or turbine‚ forming a type of internal combustion
