POSITION SENSOR AND COMPRESSOR
First Claim
1. A sensor (10), particularly one that can be employed for detecting the position of a piston (1) of a compressor (15), the piston (1) being axially displaceable inside a hollowed body (2), the compressor (15) comprising a valve blade (9), this blade (9) being positioned between a head (3) and the hollowed body (2), the sensor (10) being characterized by comprising a probe (2) electrically connected to a control circuit (12), the probe (20) being capable of detecting the passage of the piston (1) at a point of the hollowed body (2) and signaling this to the control circuit (12).

Abstract
A position sensor (10) is described, particularly a sensor (10) applicable to a linear compressor (15), for detecting the position of the piston (1) and preventing the latter from knocking against the head (3) located at the end of its stroke. One of the objectives of the present invention is to provide a sensor (10) capable of detecting the position of the piston (1), which can solve the problem of collision of the latter with the head (3) altogether and that is easy to build and to install, thus reducing the production and manufacture costs of the compressor (15). The piston (1) being axially displaceable inside a hollowed body (2), the compressor (15) comprising a valve blade (9), the blade being positioned between the head (3) and the hollowed body (2), the sensor (10) comprising a probe (20) electrically connected to a control circuit (12), the probe (20) being capable of detecting the passage of the piston (1) by a point of the hollowed body (2) and signalling this to the control circuit (12).
