TLDR
In this article, a rocker arm engine brake system for an internal combustion engine is described, where the rocker is movable by a cam operating off the cam shaft to open the exhaust valve of a cylinder at the usual time in the piston cycle.Abstract:
A rocker arm engine brake system for an internal combustion engine in which a rocker arm is movable by a cam operating off the cam shaft to open the exhaust valve of a cylinder at the usual time in the piston cycle; and when it is desired to retard the speed of the engine, a lash piston in the rocker arm is hydraulically extensible at the will of the operator to take up the usual lash between the rocker arm and the exhaust valve so as to enable an auxiliary cam operating off the cam shaft to effectively cooperate with the rocker arm to open the exhaust valve at a time toward the end of a compression stroke of the piston so as to dissipate the energy of gases of compression from acting upon the piston. Separate passages in the rocker arm shaft are utilized for providing fluid for operating the lash piston and for general lubrication. The passages are interconnected by bleed holes. Selective control of the hydraulic system is obtained by means of a solenoid operable valve.read more

Internal combustion engines with combined cam and electro-hydraulic engine valve control
TL;DR: In this paper, an internal combustion engine has electrically controlled hydraulic linkages between engine cams and engine cylinder valves, and hydraulic fluid is selectively released from the associated hydraulic linkage to permit lost motion between the cam and the engine cylinder valve.

Four-cycle internal combustion engines with two-cycle compression release braking
TL;DR: In this paper, an inernal combustion engine (10) has engine cylinder intake and exhaust valves (30, 60) that are operated by intake/exhaust cams (40, 70) via hydraulic linkages (54, 84).

Engine retarding method and apparatus
TL;DR: In this article, a process and apparatus for the comprescence release retarding of a multi-cylinder four cycle internal combusion engine is described, where the process provides a comprescion release event and a bleeder event or a second compression release event for each engine cylinder during each complete engine cycle while employing only one intake valve opening per engine cycle.
