Title: Suspension system for motor vehicles and damping valve
Inventor: RUNKEL WALTER DIPL ING DR
IPC: B60G17/056
Filed: 1993-04-29
Abstract: The present invention relates to a suspension system, especially for motor vehicles, with at least one hydraulic spring strut (2/4). When the spring strut (2/4) is compressed, hydraulic medium is displaced into a spring energy store (16/18), from which it flows back again during the rebound. At least the rebound flow of the spring strut (2/4) is led by way of a flow path (26) of a damping valve (22/24) and damped in that the flow path (26) is constantly alternately closed and re-opened by means of a valve element (30). At the same time, a bypass (40) bypassing the valve element (30) is provided, in such a way that in an essentially zero-flow condition, pressure equalisation between the sections of the flow path (26) arranged on both sides of the valve element (30) is ensured by way of the bypass (40) and when a flow occurs the bypass (40) essentially loses this pressure equalising function. The bypass (40) is opened or closed by a sealing device (44) controllable as a function of the respective flow and/or pressure conditions. For this purpose the sealing device (44) has a step piston (80) which is guided in a freely movable way and pressure-equalised in such a way that the sealing device (44) in the static, essentially zero-flow condition has a tendency to open and in the dynamic condition a tendency to close due to the flow-induced variation of the pressure conditions. <IMAGE>

In the flow direction, the clear height of the lower chamber (10) decreases continuously, with the result that the pressurization of the high-performance filter forming the bottom of the module is evened out. <IMAGE>

Patent DE-4328536-A1 (DE)
Title: Rotary nozzle
Inventor: NEY JOERG DIPL ING
IPC: B08B9/04
Filed: 1993-08-25
Abstract: In the area of duct cleaning (sewer cleaning), use is made, in order to clean pipes and ducts, of rotary nozzles which are arranged at the front end of a hose line for pressurized cleaning fluid. The rotary nozzles are made to rotate by laterally discharged cleaning fluid which is subjected to high pressure, the speed of the rotary nozzles being dependent, in an uncontrolled manner, on the quantity and the outflow rate of the cleaning fluid. Such rotary nozzles of the conventional type rotate at very high speeds, which results in pronounced atomization of the discharged cleaning jet and consequently considerably reduces the cleaning force of the cleaning jet. The object of the invention is to provide for the easy detachment of even firmly adhering contaminants in the pipes which are to be cleaned, grease residues and pipe coatings from the inner surface of the pipes. For this purpose, the rotary nozzles of the type according to the invention have spraying nozzles which are mounted such that they can be rotated about an axis parallel to the longitudinal axis of the rotary nozzles, the outlet opening of the spraying nozzles being arranged at an angle with respect to the longitudinal axis of the rotary nozzles. The outlet openings of the spraying nozzles are preferably arranged virtually at right angles with respect to the longitudinal axis of the rotary nozzles. The novel rotary nozzle is suitable for use for cleaning pipes and ducts in the private and public sectors. <IMAGE>
