Computer Controlled Balance of Reciprocating Masses Unit

Reciprocating engines consist of a piston reciprocating in a cylinder and connected to a crank shaft by a connecting rod. This cover includes a switch, which allows automatically stops the drive motor if the cover is opened. The Computer Controlled Balance of Reciprocating Masses Unit is mounted on an anodized aluminum structure with panels of painted steel. It includes rubber elements to have a vibration isolation and a transparent protective cover protects students from the moving crankshaft and allows the visibility of the practical exercises and elements of the unit.
