  • METHOD FOR OPTIMIZING RESPONSE TIME OF HYDRAULIC LATCH-PIN IN CYLINDER DEACTIVATION ROCKER ARM
    Publication number: 20160169064
    Abstract: A method for optimizing response time of a latch in a cylinder deactivation rocker arm assembly is provided. The latch is configured to move between an engaged position with an inner arm of the rocker arm assembly and a retracted position. A major outer diameter (L1) of the latch is determined. An installed length (L2) of a spring biasing the latch is determined. A clearance (L3) between L1 and a major inner diameter of an outer arm of the rocker arm assembly is determined. A radial clearance (L4) between a cage coupled to the outer arm and a major inner diameter of the latch is determined. A minor diameter (L5) of the latch is determined. A relationship between the response time of the latch and L1, L2, L3, L4 and L5 is established. Components of the cylinder deactivation rocker arm assembly are selected based on the relationship.
