Definitions

  • This invention relates to an improved variable lift cam follower.
  • the variations of the two controls can be manual, or can be automatic dependent upon the speed and load requirements on the engine either hydraulically, pneumatically or electrically, or can be part automatic and part manual so that the driver can select himself the control for either economy or performance.
