A waste gate cut-off valve may be disposed in the waste gate actuator passage and may block the waste gate actuator passage in response to an engine braking operation of the engine. Alternatively, a snubber may be disposed in the waste gate actuator passage.

摘要： 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.

摘要： An exhaust brake and method of operating an exhaust brake are disclosed. The exhaust brake may have a housing having a central opening and a boss with a central bore, wherein the central bore intersects the central opening. A butterfly gate may be pivotally mounted in the central opening. The butterfly gate may have a bypass opening provided in an outer edge of the butterfly gate, and an upstream side. A dual-diameter piston may be slide-ably disposed in the central bore. The piston may have a lower end received in the bypass opening and an upper end distal from the bypass opening. One or more passages may extend between the central opening and the central bore at the upstream side of the butterfly gate, and a spring may bias the piston lower end into the bypass opening. The piston lower end may selectively unblock the bypass opening responsive to the application of static exhaust gas pressure to the piston upper end. The shape of the bypass opening and the piston lower end may be selected so that piston lower end fits closely within the bypass opening and thereby removes soot build up in the opening as a result of operation of the exhaust brake.

摘要： The relatively complex and expensive "control valves", which are conventionally used in certain compression release engine brakes for such purposes as filling, isolating, and venting the high pressure portions of the hydraulic circuits in the engine brake, are eliminated and more direct means are provided for performing these functions. In brakes having a mechanism for resetting each slave piston, the high pressure portion of the circuit is filled through a selectively openable aperture in the slave piston. In brakes having a mechanism for automatically adjusting slave piston lash or for limiting ("clipping") the forward stroke of the slave piston, high pressure circuit fill is provided through a simple check valve. In systems in which hydraulic fluid is temporarily displaced from the high pressure circuit, a simple accumulator is provided to store hydraulic fluid for quick refill. A single such accumulator may replace multiple control valves.
