Abstract
Official abstract text for this publication.
A system for actuating one or more engine valves for positive power operation and engine braking operation is disclosed. In a preferred embodiment, an exhaust valve bridge and intake valve bridge each receive valve actuations from two sets of rocker arms. Each valve bridge includes a sliding pin for actuating a single engine valve and an outer plunger disposed in the center of the valve bridge to actuate two engine valves through the bridge. The outer plunger of each valve bridge may be selectively locked to its valve bridge to provide positive power valve actuation. During engine braking, application of hydraulic pressure to the outer plungers may cause the respective valve bridges and outer plungers to unlock so that all engine braking valve actuations are provided from a rocker arm acting on one engine valve through the sliding pin.
First claim
Opening claim text (preview).
What is claimed is: 1. A system for actuating one or more engine valves, comprising: two exhaust valves; an exhaust valve bridge extending between the two exhaust valves, said exhaust valve bridge having a central opening extending through the exhaust valve bridge, a recess formed along the central opening, and a side opening extending through a first end of the exhaust valve bridge; an exhaust side sliding pin disposed in the exhaust valve bridge side opening, said exhaust si…
