With a cylinder position recognition system, combination body between the piston and the cylinder which is driven by a linear motor, linear motor compressor, and inductive sensor

摘要

With the cylinder position recognition system, and a combination thereof with a cylinder and piston driven by a linear motor, a support structure forming a (12) an air gap (4), the air gap present invention, (12) A piston (1) which is connected to a motor winding generating a variable magnetic flow along a portion (6), a cylinder having a head at one of its ends (2), a magnet (5) at least , in order to move inside the displacement path, including in part, the magnet is driven by the electromagnetic flow (6) the motor windings, the air gap the piston (1) of the cylinder by displacement of the magnet at least (12) a piston (1) that reciprocates within the (2), inductive sensors disposed in a location of the displacement path of the magnet (5) A (8), the piston (1) is closest to the head of the cylinder When it reaches the position, a cylinder and a piston provided with inductive sensor and (8) to generate a voltage signal inductive sensor detects the change in magnetic field resulting from the corresponding position of the magnet, resulting from a change in the magnetic field I will disclose the combination of the body. Further comprising a combination structure between the piston and the cylinder as in the present invention, recognize that it is possible to position the cylinder, the present invention discloses a linear motor compressor.
