Patent DE-19511548-A1 (DE)
Title: Nitrous oxide reduction system in vehicle engine exhaust
Inventor: BOEGNER WALTER
IPC: B01D53/94
Filed: 1995-03-29
Abstract: The engine (1) is operated alternately in lean and stoichiometric or enrichment conditions. In lean conditions, the nitrous oxide (NOx) is received by an absorber (3), which is regenerated under stoichiometric or enrichment conditions.The hydrocarbons (HC), carbon monoxide (CO) or nitrous oxide (NOx) contained in the exhaust gas are measured downstream of the absorber. The engine is changed over to lean operating conditions as soon as the hydrocarbon or carbon monoxide content of the gas exceeds a predetermined value or the nitrous oxide content falls below such a value. Where there is a sensor (4) for the gas contents in the exhaust pipe downstream of the absorber, the signal from this can regulate the proportions of fuel and air supplied to the engine.

Title: Hydraulic safety valve, with non-return valve in consumer line
Inventor: MICHAELIS LOTHAR DIPL ING
IPC: F15B20/00
Filed: 1996-02-13
Abstract: The spring loaded slide of an additional valve is loaded by the primary pressuriser so as to connect the line (28) to the tank (36) off this pressure, using a pressuriser load spring adjusted so the slide reacts at lower pressure than the primary control piston. The valve is composed of the safety valve piston (72) which rides freely relative the slide (42) and reacts to a lower pressure than either slide or controller. The free travel between slide and piston is set so the piston entrains the slide after a pre-set path. Thus both slide and piston (42,72) are equipped with entraining sectors (76,74) for the piston to take the slide with it, slide and piston loaded by separate concentric coiled springs (76,86). The cone valve slide (42) is milled out (68) to vary the valve section and also waisted (64) between cone valve and milled recesses (68). The effective diameter of the slide on the consumer side should equal or slightly undershoot the slide section facing the controller.

Filed: 1996-05-07
Abstract: A jet non-return valve incorporated in gas or fluid pipes has a jet ring which is held centred within a valve housing by projections from the housing, which also co-axially surround a jet insert. A circular valve is inserted in the ring with its end facing the oncoming flow. The valve slides back and forth. In the open position it to provides flow access to circular orifices respectively between itself, the housing and the insert. In the closed position the valve rests on a seat formed on one side by the housing and on the other by the jet insert, closing the narrowing circular passage between the housing and jet insert.
