Abstract
Each of end blocks is provided with a first pressure fluid communicating passage for communication between a first pressure fluid inlet/outlet port and a third pressure fluid inlet/outlet port, a second pressure fluid inlet/outlet port, and a second pressure fluid communicating passage which communicates with a second pressure fluid passage and a first pressure fluid passage communicating with a driving section. A passage of a sensor attachment rail communicates with the third pressure fluid inlet/outlet port and the second pressure fluid passage or the second pressure fluid passage and the third pressure fluid inlet/outlet port by the aid of piping studs.
Claims9
A linear actuator comprising:
- a driving section;
- a movable member for making displacement under a driving action of said driving section;
- a pair of end blocks connected to a first end and a second end of said driving section respectively and provided with a plurality of pressure fluid communicating passages communicating with pressure fluid inlet/outlet ports;
- and
- a connecting member formed with a passage in an axial direction and connected to said pair of end blocks at both ends thereof;
- attachment members for alternately attaching said connecting member to said end blocks at respective positions that are shifted from each other by a predetermined distance in said axial direction,
- wherein said pressure fluid communicating passages communicating with said passage of said connecting member are switched to change flow passages by detaching said connecting member from one of said respective positions, displacing said connecting member by said predetermined distance in said axial direction and attaching said connecting member in another of said respective positions.
