IPC: F16F1/387
Filed: 1985-06-03
Abstract: The invention relates to an elastic bearing for the bearing of the driver's cab of a lorry having a rubber/metal component (1) which consists of an inner, cylindrical metal component (2), which is connected to the driver's cab, and of an outer metal component (3), between which metal components a rubber layer (4) with a web (5) is vulcanised in in a securely adhering fashion. The outer metal component (3) contains a longitudinal slot (6) and, during assembly, is pressed into a receptacle eyelet (14), also having a cylindrical internal diameter, with radial prestressing. The receptacle eyelet (14) is connected to the frame of the vehicle. The relatively thick rubber layer (4) is vulcanised onto the inner metal component (2) whilst the narrow web (5) lies in a radial plane. The outer metal component (3) is shaped at one end side to form a stop (11). By virtue of the narrow rubber web (5), the bearing only has small restoring forces in the axial and radial direction and in the case of a rotation, the spring constants in the axial and radial direction rising steeply after a small deflection. <IMAGE>

Patent DE-3532714-A1 (DE)
Title: Superinsulation which can be pressure-loaded
Inventor: GERHOLD JUERGEN DR
IPC: F16L59/065
Filed: 1985-09-13
Abstract: The invention relates to superinsulation which is at the same time used as a spacer between two surfaces which can be pressure-loaded, mutually crossing webs being provided in at least two layers, with the interposition of a film. In order to support pressure force, webs which are placed in a cruciform manner one above the other form contact columns at the intersections, which contact columns are compressed to a certain extent when they are stressed. The temperature gradient between the cold boundary surface and the hot boundary surface causes thermal contraction of differing severity of the webs which are arranged in layers, which has the consequence that the intersections of the webs are no longer located one above the other and the contact columns are positioned obliquely. In the worst case, there is no contact column whatsoever. The invention is based on the object of suppressing sliding relative movements of the insulating layers, so that the locations of the contact points of the webs remain defined in order to prevent film damage and hence to prevent adversely affecting the insulating effect. The solution of the object is that the webs are divided into spacer packets and the thermal contraction of the composite material which is used for the webs is matched to the thermal contraction of the cold surface. The intersections are still unambiguously defined after the cooling phase, and the contact columns are maintained, the curvatures and oblique positions of the contact columns being reduced to an acceptable level.

Patent DE-3620122-A1 (DE)
Title: Actuating drive
Inventor: AUER WERNER DR ING
IPC: H02K7/06
Filed: 1986-06-14
Abstract: An actuating drive is proposed for producing a linear motion with high resolution. A stepping motor 1 of the swashplate motor type, in the case of which an axial tooth system 12 of the rotor 11 is sequentially engaged with a tooth system 11 on the stator side, drives a recirculating ball nut 2. The latter converts the rotor movement into a longitudinal movement by means of a spindle 3. In order to guide the spindle 3 without any play, a second recirculating ball nut 16 is clamped to the first recirculating ball nut 2. Both the attachment of the drive to a holder and its attachment to the part which is to be actuated are provided with a universal joint. These joints are installed with cross-spring joints which carry out small tilting movements very precisely. The motor can be designed in a redundant manner by arranging a second coil circuit. In consequence, a more reliable and higher precision actuating drive is created. At the same time it is distinguished by a compact construction. <IMAGE>

Title: Switching and safety valve for high-pressure washing systems, for example in public service vehicles
IPC: F16K11/065
Filed: 1986-10-25
Abstract: A control piston (24) is arranged in a valve housing (11) in a manner which allows it to be displaced transversely to the axial direction of a pump connection opening (12) and of a consumer connection opening (13). In the region displaceable relative to the two abovementioned openings, the control piston (24) is designed as a flat slide and is provided on both sides with sealing plates (26). These sealing plates (26) and the flat-slide region are provided with a through hole (25) which, in one possible position, is in alignment with the pump connection opening (12) and the consumer connection opening (13). The sealing plate (26) lying in the region of the pump connection opening (12) is provided with a further throughflow hole (30) which is arranged offset in parallel to the through hole (25). If the control piston (24) is displaced to the right within the valve housing (11), the throughflow opening (30) moves into the cross-sectional area of the pump connection opening and it is then possible for pumped medium to flow via a return opening (14) also. Impermissible increases in pressure are thereby avoided. <IMAGE>
