摘要： A third motion transfer mechanism transfers valve actuation motion from a second motion source to a first engine valve. A motion decoupler is configured to selectively discontinue the transfer of motion from a first motion transfer mechanism to the first engine valve. Furthermore, a reset mechanism is configured to selectively discontinue, based on operation of a second motion transfer mechanism, the transfer of motion from the third motion transfer mechanism to the first engine valve. The third motion transfer mechanism may comprise a master piston and a slave piston in fluid communication with each other via a hydraulic circuit, the master piston being configured to receive motion from the second motion source and the slave piston being configured to transfer motion to the first engine valve.

摘要： Apparatus and methods for hydraulic valve actuation of engine valves are disclosed. An exemplary embodiment of the present invention may include a lost motion piston assembly that transfers motion between first and second rocker arms to selectively provide auxiliary engine valve actuation motions to the engine valves for engine operations such as engine braking and exhaust gas recirculation. The lost motion piston assembly may reduce or eliminate transient loads that may otherwise be transmitted to engine valve train elements during the times that lost motions systems are turned on and off for auxiliary valve actuations.

摘要： A system for controlling actuation of an engine valve comprises a pivot and a torsion spring having first and second legs operatively connected to the pivot. A lever arm is adjustably affixed to and extending away from the pivot, and is further rotatable about a pivot axis of the pivot between a retracted position and an extended position and vice versa relative to a motion conveying component. Furthermore, a housing is provided having a pivot bore formed therein with the pivot rotatably disposed in the pivot bore. The housing further comprises a first and second openings intersecting with the pivot bore such that the first and second legs extend out of the first opening and the lever arm extends out of the second opening. When a first force is applied by the motion conveying component to the lever arm, such first force maintains the lever arm in the extended position.

摘要： 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.

摘要： A switching finger follower for an engine valve train utilizes an adjustable support assembly that eliminates potential for partial engagement during operation. A lever engagement member or latch is disposed for movement on the follower body and interacts with a lever to provide a constant contact geometry. The finger follower may be configured as a lost motion device and may include a biasing assembly and a travel limiter. The latch may support the lever in at least one precise position and may support the lever in a second position for partial lost motion, or permit the lever to pivot free of the latch for complete lost motion, as in cylinder deactivation applications.
