摘要：
Apparatus for maintaining the cam follower for operating a valve for an internal combustion engine in biased engagement against the cam includes a first spring operative to bias the cam follower under a low speed engine operating condition and a second spring series-connected to the first spring and having a spring constant greater than that of the first spring operative to bias the cam follower under a high speed engine operating condition.
