DEVICE FOR CONVERSION OF OSCILLATORY MOTION INTO REVERSIBLE TRANSLATIONAL MOTION Russian patent published in 1998 - IPC

FIELD: instrument and vacuum engineering. SUBSTANCE: device contains drive member made in the form of long nonmagnetic hollow housing connected with mechanical oscillation generator and oriented by its longitudinal axis along direction of oscillations and driven member made in the form of ferromagnetic plate mounted for translational motion at spaced relation to housing along its longitudinal axis. Located inside housing is ferromagnetic member which is engageable with its inner lateral surface and is free for axial displacement relative to housing; it is flexible connected with one inner end of housing. Mounted rigidly on outer lateral surface of housing on side opposite to ferromagnetic plate near one end is permanent magnet which may perform fixed axial displacement along housing in guides. EFFECT: enhanced efficiency. 2 dwg
