  • Patent number: 5798453
    Abstract: A pressure sleeve for a vibration pickup, has a body part with a central opening for a mounting element and a supporting surface to be placed on a component causing vibrations, a detecting element arranged radially outwardly on the body part with an axial pretensioning, a spring providing the axial pretensioning of the detecting elements, and an abutment provided on the body part for the spring, the abutment including at least two curved portions provided on an outer peripheral of the body part and formed by wedging of a material of the body part.

  • Patent number: 4942856
    Abstract: An ignition distributor which is driven by an engine includes a structural division between the engine block and ignition distributor and has a separable connection, which is embodied as a claw coupling. For corresponding operational parts dimensionally stable, self-lubricating and wear-resistant plastic is used at the force transfer points of the claw coupling. Thus, it is possible to operate the claw coupling in a dry-running manner which does not require an encapsulated lubrication.

  • Patent number: 4088853
    Abstract: To reduce the axial length of distributor-breaker assemblies and to provide for reliable placing of a second upright bearing for the distributor shaft, a holding plate to which a bearing is floatingly attached is clamped in the distributor housing by means of a claw clamp, tightened by a transverse plate against itself and against a shoulder formed in the inner side wall of the distributor, the claw clamp being formed as a partly circumferential ring seated in a groove of the distributor.

  • Patent number: 4033315
    Abstract: To provide an easily manufactured ignition distributor in which two bearings support the distributor shaft, the lower bearing is molded or otherwise secured into the housing structure, whereas the upper bearing is supported on a transversely extending support member, typically a support plate which is seated within the housing, for example bearing against a shoulder, against seating lugs, or the like, so that the entire ignition distributor structure can be constructed with small compact size.
