Title: Remotely adjustable car shock absorber - includes valve restoration spring with limited expansion determining emergency position of sliding adjuster of flow constriction
Inventor: SCHNEIDER STEFFEN DIPL ING
IPC: B60G17/08
Filed: 1991-03-09
Abstract: An electromagnetic valve (10) built into a piston (4) incorporates a cylindrical control slider (16) with several steps, and a groove (31) bounded by a control edge (33) which determines the cross-section of a variable constriction (37) between two working spaces (21,22).

Title: Displaceable divided piston for changing rotary position of shaft in engine - has support part and end piece each with prefab. inclined gearing sections to form gearing pairs with adjoining components
Inventor: GOLOVATAI-SCHMIDT EDUARD DIPL
IPC: F16D3/10
Filed: 1992-06-01
Abstract: The support part (7) for the piston plate (9) has internal gearing and the end piece (8) has external gearing, or vice versa. The gearing can be produced by the cold flow pressing process which requires no subsequent finishing. The inclined direction of the gearing differs from each other to create the largest possible adjustment range with small axial displacement of the piston. A seal on the end piece or support part follows the piston movement and prevents leakage losses. It provides an effective seal between the axially displaceable piston and the component coaxially enclosed by or enclosing the piston. USE/ADVANTAGE - Gearing has homogeneous structure ensuring long service life and is useful for camshaft drives in internal combustion engines.

Title: Shaft which can be closed off in a sealed manner and intended for subatmospheric pressure drainage systems
Inventor: MICHAEL HARALD
IPC: E03C1/122
Filed: 1993-02-13
Abstract: The shaft serves for receiving the shut-off valve (24) and the associated control device (22) of a service connection of a subatmospheric-pressure drainage system.

Title: Aerostatic bearing arrangement
Inventor: BUCHNER KURT DIPL ING
IPC: F16C32/06
Filed: 1993-03-12
Abstract: The invention offers the possibility of using rotatably mounted machine elements, for example textile transfer rollers, even at high speeds and temperatures. In the case of conventional units mounted in rolling bearings, these conditions led to unsuitable service lives. The bearing arrangement can be produced economically. It comprises a stationary shaft (1) which is provided with axial (2) and radial (7) holes for the supply of compressed air. Mounted on the shaft (1) is an aerostatic floating bearing which consists of two bearing rings (5, 6) with a radial charging gap (8) between them. This is formed, for example, by segments (11') ground axially into the bearing rings. The supporting air cushion is formed in the radial bearing gap (9) between the bearing rings (5, 6) and the housing (3). The fixed bearing is formed by the bearing rings (11, 12) and the two axial discs (10) which are inserted into the housing (3). This is a combined radial/thrust bearing. The radial charging gap (14) supplies the radial bearing gap (15). In the further course of the flow of air, the radial bearing gap (15) acts as a charging gap for the axial bearing gaps (13). This guarantees the axial load-bearing capacity. <IMAGE>
