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
