  • Piston-mounted power generator, especially for telemetry systems
    Patent number: 5459360
    Abstract: A piston-mounted power generator has a piston-mounted magnet unit (1) formed of a coil (2) with a permanent magnet core (3) that is fitted with pole extensions (5, 6). The unit (1) is mounted to the piston skirt (8) with the pole extensions having a small clearance from the inner wall (10) of the piston cylinder formed by cylinder wall liner (12). Shallow grooves (14) are machined into the cylinder wall (10). The grooves (14) have a crescent-shaped longitudinal cross section, that extends circumferentially in the cylinder wall (10) for a distance that is only slightly longer than the width of the pole extensions. The width of each groove (14) is equal to the spacing between the pole extensions (5, 6) and the axial spacing between the adjacent pairs of grooves (14) is equal to the thickness of the pole extensions (5, 6).
