Definitions

  • An additional disadvantage of the know arrangement is that it does not have an easy way or a proper lash adjusting means to set the valve lash.
  • US 2005/000499A1 (RUGGIERO BRIAN ET AL, JAN. 6, 2005 ) disclosed a rocker brake with one braking piston in the rocker arm.
  • FIG. 2 is a function chart illustrating the general relationship between the normal engine operation 20 and the added engine braking operation 10 according to one version of the present invention.
  • the small cam lobe(s) on the exhaust cam 230 are skipped, as shown in block 240, due to a gap 234 among the valve train components, to produce the main exhaust valve lift profile 220m for the normal engine valve event 20N.
  • the engine brake control means 50 controls the motion of the engine brake actuation means 100 between an inoperative position 0 and an operative position 1.
  • FIG. 5A When engine brake is needed, the engine brake control means 50 is turned on ( FIG. 5A ) and the engine oil is transmitted to the engine brake actuation means 100 through the braking fluid circuit.
  • FIG. 4B shows that the engine oil from flow passage 214 can get to the bottom of the lash adjusting screw 110 because its stem 191 is smaller than the bore 190 of the ball-locking piston 165 in which the braking piston 160 slides. Oil pressure overcomes the force of spring 198 and pushes up the rocker arm 210 for a clockwise rotation to take up the gap 234 between the cam 230 and the cam follower 235 ( FIG. 4B ).
  • the valve body 60 has the inlet port 111, the outlet port 211 and the discharge port 222.
  • a ball 67 is mounted in a bore 75b and separates the inlet port 111 and the outlet port 211.
  • a movable valve member for example, a cylindrical body 64 is disposed in a bore 75a to separate the outlet port 211 and the discharge port 222.
  • a plunger 66 is disposed between the cylindrical body 64 and the ball 67.
  • the three ports are separated or sealed from each other by O-rings 65 and 68.
  • a screen 69 can be installed before the inlet port 111 to prevent any contaminants from getting into the valve.
  • the ball-locking piston 165 is biased up by a spring 177r and a gap 185 is formed between the ball-locking piston 165 and the reset stop 182.
  • the gap 185 is so designed that the ball-locking piston 165 will not touch the reset stop 182 during the normal engine operation.
  • the engine brake reset means 150 may work without the reset spring 177r because the ball-locking piston 165 can be unseated by the reset stop 182 to reset and turn off the engine brake actuation means 100.
  • the ball-locking piston 165 When the ball-locking piston 165 is unseated, there may be oil leakage through the annular gap between the small piston or stem of the ball-locking piston 165 and the bore 450 in the valve bridge 400.
  • the engine brake reset means 150 can also be disabled by removing the reset stop 182, then the motion of the whole cam is transmitted to the exhaust valves 300 to produce an enlarged main valve lift profile and a secondary valve lift profile for the engine braking operation. Without the reset stop 182, the reset spring 177r is needed to unlock the ball-locking device and turn off the engine brake.
  • FIGS. 17A and 17B are schematic diagrams of another embodiment, which is not part of the claimed invention with the engine brake actuation means 100 integrated into the valve bridge 400.
  • the engine brake actuation means 100 is a ball-locking device similar to that shown in FIGS. 11A and 11B .
  • a plurality of balls 175 are restrained by three surfaces on three different elements of the engine brake actuation means 100.
  • the first surface is the tapered surface 192 on the braking piston 160 that is slidably disposed in a large bore 190 in the valve bridge 400.
  • the second surface is the bottom flat surface of the bore 190, and the third surface on the ball-locking piston or plunger 165 that is slidably disposed in a small bore 450 in the valve bridge.
  • the engine brake reset means 150 includes the ball-locking piston 165 and a reset stop 182 on the engine cylinder head 500.
  • Oil pressure at the second level or higher overcomes the load of the braking springs 177 and pushes the braking pistons 160 down and out of the bores 190 to the exhaust valves 300.
  • the braking pistons 160 are at the operative position now and their motion or stroke is limited by the exhaust valves 300 and equal to the gap 234 as shown in FIG. 18B .
  • the control fluid displaced the braking pistons 160 takes up the gap 234 and forms a hydraulic linkage between the valve bridge 400 and the exhaust valves 300.
  • FIG. 20D shows a different braking piston assembly that can be used for the embodiment which is not part of the claimed invention, shown in FIGS. 20A and 20B .
  • the two braking pistons 160a and 160b are biased toward each other by the braking springs 177a and 177b that are held and guided by a screw 148 and a screw nut 149.
  • the inoperative surface 145 and the operative surface 140 are cylindrical.
  • the two braking pistons 160a and 160b are separated by a clip ring 159 ( FIG. 20D ) that can be mounted in a groove (not shown) at the center of the bore 415 ( FIGS. 20A and 20B ).
  • 25A shows the retracted position of the toggle device where the two pins guided in the slot 137 that is cut through a guiding piston 162 are pushed to the left by the spring 156.
  • the guiding piston 162 slides in a horizontal bore 260 in the braking housing 210.
  • the slot 137 in the guiding piston 162 has a width that is about the same as or slightly larger than the diameter of the two pins and a length that is smaller than the diameter of the bore 190. There will be always contact (no separation) among the braking piston, the lower pin, the upper pin and the adjusting screw due to the upward force of the spring 177 that is secured to the brake housing 210 with at least one screw 179.
  • the engine braking control means When engine brake is needed, the engine braking control means is turned on and oil pressure can push both pistons 162 and 164 to the right against the preloads of the spring 156 and 177.
  • the actuation piston 164 can be moved to the right further to lock the two pins or toggles 184 and 186 in a straight position, aligned with the adjusting screw 110b and the braking piston 160, as shown in FIG. 25B .
  • the toggle device is locked to its extended position on the operative position.
  • the motion limiting means for this toggle device is unique.
  • the angle between the two pins or toggles 184 and 186 decides the height difference 130, while the angle itself is controlled by the two pistons 162 and 164.
  • the bleeding orifice 168 in the guiding piston 162 is designed to eliminate hydraulic lock.
  • FIG. 35 is a schematic diagram of another engine braking apparatus, which is not part of the claimed invention, with a wedge system at the "Off" position.
  • the only difference from FIG. 34 is that the slant surface 140 on the braking piston160 is perpendicular to the brake actuation linkage 210.
