Components with hydraulic valve lash adjustment

Finger follower with hydraulic pivot element

  • Contact between finger follower and cam preferably by means of needle bearing cam roller
  • Very low valve train friction
  • Very simple assembly of cylinder head
  • Oil can be easily fed to the cylinder head
  • Very little space required
 

Sheet steel finger follower with cam roller and pivot element

  • Formed from sheet steel
  • Height of valve stem seat on valve is freely selectable
  • Optionally with oil feed hole
  • Optionally with retaining clip - simplified cylinder head assembly
  • Very large load-bearing surfaces in the half-sphere area and valve contact face
  • Highly cost-effective

Cast finger follower with cam roller and pivot element

  • Complex lever geometries possible
  • High load carrying capacity
  • Optionally with oil feed hole
  • High rigidity dependent on design
  • Low mass moment of inertia dependent on design

Hydraulic pivot element

  • Held together by means of polygon ring
  • Reliable support of high transverse forces
