Abstract:
new power machine concept has been designed and analyzed for production, and proof of principle subscale tests have been performed, with positive results. The machine design concept is applicable as a compressor, pump, motor, or engine. Simplicity of design based on spherical ball pistons enables a low moving part count, high power to weight ratio, elimination of valve train and water cooling systems, and perfect dynamic balance.

The new design concept utilizes novel kinematic design to completely eliminate inertial loads that w ....etc

A ball valve (like the butterfly valve, one of a family of valves called quarter turn valves) is a valve that opens by turning a handle attached to a ball inside the valve. The ball has a hole, or port, through the middle so that when the port is in line with both ends of the valve, flow will occur. When the valve is closed, the hole is perpendicular to the ends of the valve, and flow is blocked. The handle position lets you 'see' the valve's position.

Ball valves are durable and usually work to achieve perfect shutoff even after years of di ....etc

Abstract:
Tribometer is an instrument that offer precise and repeatable wear/friction measurement of a surface. Friction testing can be carried out in various environments to simulate the real life scenarios. Tribometer testing rigs can take numerous geometries but generally take the form of a loaded probe that impinges the sample that travels in a circular or reciprocating fashion. In this seminar we present different methodology used in advanced Tribometer and the working principle of Pin on disc Tribometer

Abstract:
pin-on-disk tribometer is an advanced Tribometer with precise and repeatable measuring of the friction and wear properties of combinations of metals and lubricants under selected conditions of load, speed and temperature. the elements of the tribometer are a pin sliding on the flat face of a disk rotating in a vertical plane, with provisions for controlling load, speed and oil temperature, and for measuring friction. The test oil is contained in a cup in which the disk rotates ,The pure sliding used in this test causes b ....etc

Introduction

From the day machines with reciprocating piston has come into existence efforts have been undertaken to improve the efficiency of the machines .The main drawbacks of reciprocating machines are the considerably large number of moving parts due to the presence of valves , greater inertial loads which reduces dynamic balance and leakage and friction due to the presence of piston rings . The invention urges has reached on Rotary machines .

One main advantage to be gained with a rotary machine is reduction of inertial loads and ....etc
