Cam Analysis Apparatus Model MT 013

Sci-tech Cam Analysis Apparatus Model MT 013 allows the dynamic investigation of cam mechanisms, as
used in motors for actuation of the valves. The cam mechanism consists of 4 interchangeable cam plates and
2 different tracers. A mass and a spring are used to simulate the valve. In order to demonstrate the so-called
“valve wobble”, the spring rate, mass and speed are adjustable within broad limits. A plotter allows the actual lift curves to be recorded. The open design allows the observation of every detail of the movement process. A
stroboscope (not supplied) can be used to provide a particularly impressive view of the movement process and
lift.
