## Abstract

The present invention refers to a linear engine for compressor, and to a compressor provided with a linear engine. The linear engine for compressor comprises at least a stator consisting of a first core (2) and a second core (3), and at least a cursor (4), wherein said first core (2), cursor (4) and second core (3) are concentrically disposed. Said first core (2) is substantially defined by at least two different bodies (21, 22) and provides attaching means (6, 7) between said two bodies (21, 22).

## Claims

### Claim 1

A linear engine for compressor, comprising a stator
comprising a first core and a second core, and a cursor; wherein the first core further comprises a
coil, wherein the first core, the cursor and the second core are concentrically arranged, wherein
the linear engine for compressor comprises:
the first core defined by at least a first body and a second body;
attaching means between the first body and the second body;
at least one of the first body and the second body defining an area for winding a coil; and
the first body being physically couplable to the second body, wherein at least the first
body comprises an annular geometry;
a compressor comprising:
a first support acting as an attaching member between the cursor and at least one
moving portion of the compressor:
a second support acting as an attaching member between the first core of the linear engine and at least a portion fixed to a carcass of the compressor;
the cursor being attached to the first support by means of a first adhesive substance;
the first core being secured to a second support by means of a second adhesive substance; and
the second support being fixed to at least the portion fixed to the carcass of the compressor by means of a third adhesive substance.

### Claim 2 (depends on 1)

The linear engine for compressor, in accordance with claim 1, wherein the first body and the second body are made of ferrous composite material and phenolic resin.

### Claim 3 (depends on 1)

The linear engine for compressor, in accordance with claim 1, wherein the first body comprises a body of annular prismatic geometry.

### Claim 4 (depends on 3)

The linear engine for compressor, in accordance with claim 3, wherein the first body has a hole disposed in a face of the first body.

### Claim 5 (depends on 1)

The linear engine for compressor, in accordance with claim 1, wherein the second body comprises an integral body defined by at least two cylindrical and concentrically disposed regions.

### Claim 6 (depends on 1)

The linear engine for compressor, in accordance with claim 1, wherein at least a portion of the attaching means comprises a hole disposed in at least one of the first body and the second body.

### Claim 7 (depends on 1)

The linear engine for compressor, in accordance with claim 1, wherein at least a portion of the attaching means comprises a protrusion disposed in at least one of the first body and the second body.

### Claim 8 (depends on 7)

The linear engine for compressor, in accordance with claim 7, wherein the second body has a protrusion disposed in a longitudinal edge of the second body.

### Claim 9 (depends on 1)

The compressor, according to claim 1, wherein the first support is made of non-metallic and non-magnetic material.

### Claim 10 (depends on 1)

The compressor, according to claim 1, wherein the second support is made of non-metallic and non-magnetic material.
