Video of Hydraulic Oscillator

Just uploaded a video on hydraulic reciprocation http://www.youtube.com/watch?v=TL63PhantE8
to my YouTube site. This video features one of the experiments my students do in the Hydraulics Lab that I teach.

This particular experiment uses a pilot control valve - a device which uses pressure applied to a control port to switch the valve's direction.

Please bookmark and check back periodically, as I have other videos in the works.

Enjoy.
