Cylinder combination driven by linear motor with recognition system and the position of the piston compressor piston linear motor

摘要

Cylinder combination driven by linear motor with recognition system the position of the piston to provide maximum functionality of the combination of piston and cylinder and piston, avoiding a collision of the piston with a cylinder head, comprising a support structure (4) forming an air gap (12); one motor winding (6) generating a variable magnetic flow at least along part of the air gap (12); a cylinder (2) having a head at one end; a piston (1) connected to a magnet (5) being driven magnet by the magnetic flux of the motor winding (6) to move inside a displacement path including at least partially the air gap (12); causing displacement of the piston magnet (1) to reciprocate within the cylinder (2); and an inductive sensor (8); characterized in that the inductive sensor (8) is arranged at a point of the displacement path of the magnet (5) coinciding with the position of the magnet (5) when the piston (1) reaches a position closest the head without colliding, so that when the piston (1) reaches this position in the path of travel, the edge position furthest from the head magnet coincides with the position of the sensor end closer to the head, thereby inducing a variation in the magnetic field applied by the magnet (5) on the inductive sensor resulting from the corresponding position of the magnet, and the inductive sensor configured to generate a signal voltage resulting from this magnetic field variation.
