Abstract

The piston cylinder assembly is extensively used in different applications including reciprocating pumps, Compressors, Reciprocating actuators and engines of vehicles. The most frequently encountered problem is generally arises with this all above equipment’s are damage occurs of piston or cylinder. Because of such a kind of damage engine life, pump life, actuators life or compressor life becomes shorter and also sometimes premature failure of piston-cylinder is noticed. Due to these engine or pump will not able to work for long time period. In this paper represented the solution of avoiding likewise problem for piston-cylinder assembly, reduces the chances of premature failure of parts and improve working life cycle of engine, compressors and pumps. One of the most widely used mechanism in hydraulic system named as cushioning mechanism provide the solution of above cases. This type of mechanism is provided at the end of piston and cylinder where hammer blow is generated during the working motion. With the help of cushioning mechanism piston speed is to be reduced at the end of each stroke. At the end result piston make contact with cylinder comparatively very low speed. Speed reduction at the end of stroke of piston, which can reduce the thrust force, which is generated on the cylinder reduced as well. In this paper represent the end portion of piston and cylinder is displayed for improving working life cycle of piston and cylinder assembly. In addition with this mechanism reduction in vibration during end of stroke is also to be achieved.
