Claims

[Scope of utility model registration request]

Two cylinders 2 and 3 are formed parallel to each other in the main body 1, and both ends of two piston rods 6 and 7 extend outward from the main body 1 from pistons 4 and 5 housed in the respective cylinders 2 and 3. Connection plate 8
, 9, and partitioned within each cylinder 2, 3 by each piston 4, 5;
In the cylinder device, the main body 1 and the connecting plates 8, 9 are relatively reciprocated by alternately supplying fluid to the main body 1, which is parallel to the cylinders 2, 3. A recess 18 is provided, and a rod 19 passing through the main body 1 is inserted into the recess 18, and both ends of the rod 19 are connected to the connecting plate 8,
Of the two fluid passages 21a and 21b, each connected to the rod 19 and partitioned within the recess 18 by a sealing member 20 provided at an intermediate portion of the rod 19,
Through one fluid passage 21a, the rod 19
A first port 23a formed at one end and a first port 24a formed at a side surface perpendicular to the reciprocating direction of the main body 1 are connected to the other fluid passage 2.
1b, a second port 23b formed at one end or the other end of the rod 19 and a second port 24b formed on the same side as the first port 24a of the main body 1 are connected to the reciprocating port 1b, respectively. What is claimed is: 1. A cylinder device characterized in that the cylinder device is configured to communicate over the entire range of a motion stroke.
