Abstract

The present invention concerns an actuator device (1) for spindles, comprising a main hollow body (2) that defines a chamber (3) slidingly housing the plunger (4) that divides the chamber (3) into a first chamber and a second chamber into which the respective ducts (7) and (8) for delivering and/or discharging a fluid (F) end. Said actuator device (1) also comprises a second hollow body (9) in which the first hollow body (2) is slidingly coupled, the second hollow body (9) being provided with a first channel (10) and a second channel (11) for the delivery and/or outflow of the fluid (F), communicating with the ducts (7, 8). The invention concerns also the related spindle and electric spindle.
