electromagnetic linear drive machine, compressor, linear actuator and electronically controlled timing valve for reciprocating engines

摘要

It is an electromagnetic linear drive machine comprising a tubular stator (1) having a longitudinal geometrical axis (w) and a permanent magnet (7) with poles oriented along the geometrical axis and moving within the stator (1). the stator (1) comprises at least two electromagnet (2) columns (a, b), each electromagnet (2) comprising a core (u) formed by a central straight segment (4) and two polar end expansions (5), all of which are oriented towards - and orthogonally - to said geometric axis (w). the columns are arranged circularly around said permanent magnet (7) and linearly displaced mutually along said geometrical axis (w). Also disclosed are a compressor and valve driven by such an electromagnetic linear driving machine.
