  • Electromechanical valve lash adjuster
    Patent number: 10316709
    Abstract: An internal combustion engine includes a cylinder head, a poppet valve having a seat within the cylinder head, a cam shaft on which is mounted an eccentrically shaped cam, and a rocker arm assembly comprising a rocker arm, a cam follower, and an electromagnetically actuated lash adjuster. The lash adjuster provides a continuously variable length fulcrum for the rocker arm. The actuator may be a piezoelectric stepper motor. The lash adjuster may be operative to vary a rate of internal exhaust gas recirculation and without requiring crank angle data.
    Type: Grant

  • Mechanical coupling devices for motorized levering-in assemblies, related electrical apparatus and methods
    Patent number: 10211608
    Abstract: Levering-in systems, particularly suitable for electrical apparatus such as switchgears, have a motor that can drive a drive shaft during a powered operation and include a mechanical coupling assembly that can physically disconnect or decouple the drive shaft from a drivetrain coupled to the motor to allow manual levering-in with a reduced user crank force and/or to inhibit damage to components of the motorized drive system.
