How Do Hydraulic Valve Lifters Work?

Hydraulic valve lifters, also known as hydraulic tappets or hydraulic lash adjusters, play a vital role in the proper operation of an internal combustion engine. They are responsible for maintaining the proper clearance, or “lash,” between the engine’s camshaft and valve train components. Here’s an overview of how hydraulic valve lifters work:

  1. Struktura:
    • Hydraulic valve lifters are small cylindrical devices typically made of metal.
    • They are between the camshaft and the engine’s valve train components, such as the pushrods, rocker arms, or overhead cam followers.
  2. Hydraulic Operation:
    • Inside the hydraulic valve lifter, a small piston mechanism operates based on hydraulic pressure.
    • The lifter is filled with hydraulic fluid, typically engine oil, which acts as a working fluid.
  3. Camshaft Interaction:
    • The camshaft has lobes or eccentric shapes that push against the lifters as it rotates.
    • As the camshaft lobe comes into contact with the lifter, it applies a force that compresses its internal piston.
  4. Lash Adjustment:
    • When the lifter’s piston is compressed, it pushes the hydraulic fluid out of the lifter through a small orifice.
    • This hydraulic fluid is expelled into the engine’s oil galleries or passages.
  5. Lash Compensation:
    • The expelled hydraulic fluid creates a hydraulic cushion or “spring” effect, compensating for any clearance or lash between the camshaft lobe and the valve train components.
    • This compensation eliminates excessive clearance and ensures that the valve train remains in constant contact with the camshaft lobes.
  6. Maintenance of Lash:
    • If there is excessive clearance or lash in the valve train due to wear or other factors, the lifter’s internal piston will extend further to maintain the necessary hydraulic pressure.
    • This extended position allows the lifter to take up the additional clearance, thus maintaining proper valve lash.
  7. Oil Pressure and Lubrication:
    • The hydraulic valve lifters rely on the engine’s oil pressure for proper operation.
    • The oil pump circulates oil through the engine, and the lifters receive a continuous oil supply to maintain hydraulic pressure and lubrication.
