Device for detecting the position of a slide valve of a pneumatic valve

摘要

The device (D) has a body (1) installed between a pneumatic distribution body (CD) and a steering nozzle (EP) of a pneumatic or electro pneumatic valve that is provided with a slide valve (T). A detection unit detects position of the valve by electrical continuity. The detection unit has a primary conductive element (5) i.e. gold-plated copper disk, secured to the valve and fixed to secondary conductive elements formed of beryllium copper springs (4), springs (9) and corner deflectors (10) such that the continuity is obtained by connecting the disk with the secondary conductive elements.
