Patent GB-1373327-A (GB)
Title: Rocker arm engine brake system
IPC: F01L1/18
Filed: 1973-06-06
Abstract: 1373327 I C engine valve gear JACOBS MFG CO 6 June 1973 [11 July 1972] 26974/73 Heading F1B Engine braking is achieved by opening the exhaust valve of an I.C. engine when the piston is near the TDC position. A device for effecting this additional opening of the valve comprises a valve-opening rocker arm pivoted on a pedestalsupported rocker shaft, a rotatable cam which operates the rocker arm but is ineffective to open the valve because of the clearance between the rocker arm and valve stem, a piston mounted in a bore in the rocker arm and movable by hydraulic fluid-pressure to a projected position in which the clearance is taken up, the fluid circuit including a control valve and one of two separate conduits extending longitudinally through the rocker shaft, the other of the conduits receiving oil from the crank-case and the conduits being inter-connected by bleed holes in a partition wall common to the conduits. Rocker arm 16 mounted on rocker shaft 21 operates two exhaust valves 12 through bridge piece 14. Rocker arm 16 is oscillated by push rod 24 and cam 25 which has a main lobe 28 which opens the valves during the exhaust stroke and an auxiliary lobe 29 which opens the valves near the top of the compression stroke. For the lobe 29 to be effective, piston 31 is projected by admitting hydraulic fluid to the space behind the piston. Fluid is fed to each rocker arm by a conduit 48 formed by dividing a bore through the rocker shaft into two conduits by a partition 49. Fluid is supplied to conduit 48 by pump 2, through a solenoid-operated valve . unit 38. When the valve unit is energized, fluid flows through ports 45 to conduit 48. When the valve is de-energized, ports 45 connect conduit 48 to a drain 70. The fluid circuit also includes a fluid-operated shuttle valve 63 combined with a check valve 65. Shuttle valve 63, Fig. 7 is moved by fluid from conduit 48 to align a cross-bore im the shuttle with a passage 61, so that fluid flows past the check-valve 65 to move piston 31. The check-valve forms an hydraulic lock preventing return movement of the piston. When pressure in conduit 48 is relieved, the shuttle is moved by spring 69 to allow fluid behind the piston to vent through duct 59. To prevent air bubbles accummulating in duct 48, it is connected by bleed holes in partition 49 to the second conduit 51 which supplies lubricating oil to the valve gear and is therefore always filled with oil from the crank-case.

Filed: 1951-11-29
Abstract: 694,623. Automatic circuit-breakers; protective cut-out arrangements. LANDIS & GYR AKT.- GES. Nov. 29, 1951 [Dec. 4, 1950], No. 28063/51. Class 38 (v) In a circuit-breaker having a trip coil 7 for instantaneous tripping on very heavy overcurrents and a thermal trip 8 for tripping on smaller overloads of longer duration, a differential relay 9 causes tripping on the occurrence of a small earth leakage current by closing contacts 12 to energise a heater 13 which causes the thermal trip 8 to trip the circuit-breaker. The relay 9 also acts directly on an armature 15 to produce tripping of the circuit-breaker directly under severe earth-fault conditions. The circuit-breaker has main contacts 5, 6 normally held closed by an overset toggle 21 extending between levers 24, 28, which are pivoted at 23 and 27 and biased by springs 22 and 26 respectively. A bell-crank 19 is normally biased by a spring 17 against a stop 18, but under fault conditions is turned by armature 14 or 15 or the thermal device 8 to collapse the toggle 21. If the fault is a small earth leakage current, this collapsing of the toggle is effected by the unbalance of the currents in the coils 10, 11 of the relay 9 resulting in the movement of a light armature 30 to trip the contacts 12, which close, the heater 13 being energised to render the device 8 effective. On the collapse of the toggle 21, the lever 24 is turned about its axis by the spring 22 to open the contacts 5, 6 and, at the same time, to reset the armature 30 and contacts 12 by means of rods 35, 36. The relaxing of the pressure on the lever 28 by the toggle 21 enables a spring 39 to turn a manual operating member 29 to the off position. The spring 26 is now able to turn the lever 28 sufficiently to reset the toggle 21 so preparing the circuit-breaker for reclosure.
