| -5- He/Smth.3/KW.18.7.34. Valve Spring Rig. A rig is being constructed by means of which it is hoped to magnify and photograph the valve motion. If this is successful we shall be in a better position to say what portion of the cam form is responsible for valve bounce, and by what modifications to the form the bouncing speed may be raised without sacrificing valve lift.
