    Abstract: Systems and methods for actuating engine valves are disclosed. The systems may include primary and auxiliary rocker arms disposed adjacent to each other on a rocker arm shaft. The primary rocker arm may actuate engine valves for primary valve actuation motions, such as main exhaust events, in response to an input from a first valve train element, such as a cam. The auxiliary rocker arm may receive one or more auxiliary valve actuation motions, such as for engine braking, exhaust gas recirculation, and/or brake gas recirculation events, from a second valve train element to actuate one of the engine valves. Master and slave pistons may be provided in the primary rocker arm. The master piston may be actuated by the auxiliary rocker arm.

    Abstract: Systems and methods for actuating engine valves are disclosed. The systems may include primary and auxiliary rocker arms disposed adjacent to each other on a rocker arm shaft. The primary rocker arm may actuate an engine valve for primary valve actuation motions, such as main exhaust events, in response to an input from a first valve train element, such as a cam. The auxiliary rocker arm may receive one or more auxiliary valve actuation motions, such as for engine braking, exhaust gas recirculation, and/or brake gas recirculation events, from a second valve train element. A hydraulic actuator piston may be disposed between the auxiliary rocker arm and the primary rocker arm. The actuator piston may be selectively locked into an extended position between the primary and auxiliary rocker arms so as to selectively transfer the one or more auxiliary valve actuation motions from the auxiliary rocker arm to the primary rocker arm.

    Abstract: The present invention is directed to an innovative, economical method or system disclosing a captive volume in a hydraulic circuit which can be selectively hydraulically or pneumatically locked, or vented in order to correspondingly maintain, or increase the total volume of the hydraulic circuit. The structural elements of an embodiment of the present invention may include an accumulator with or without a fixed solid stop, which limits its travel. The accumulator can either be a separate entity, or as an assembly within the master or slave pistons.
