PISTON AND CYLINDER COMBINATION DRIVEN BY LINEAR MOTOR WITH CYLINDER POSITION RECOGNITION SYSTEM AND LINEAR MOTOR COMPRESSOR, AND AN INDUCTIVE SENSOR |
摘要 |
The present invention discloses a piston and cylinder combination driven by linear motor with cylinder position recognition system, comprising a support structure (4) forming an air gap (12); a 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 of its ends; a piston (1 ) connected to a magnet (5), the magnet being driven by the magnetic flow of the motor winding (6) to move inside a displacement path including at least partially the air gap (12); the displacement of the magnet making the piston (1 ) reciprocatingly move inside the cylinder (2); and an inductive sensor (8) disposed at a point of the displacement path of the magnet (5), such that when the piston (1 ) reaches a position of closest approach to the cylinder head, the inductive sensor detects a variation in the magnetic field resulting from the corresponding position of the magnet, and generates a voltage signal arising from this magnetic field variation. The invention also discloses a linear motor compressor, which comprises a piston and cylinder combination of the kind of the present invention, and is capable of recognizing the position of the cylinder. |
