Abstract

A rodless cylinder comprises a cylinder tube having, at its inside, a piston which is movable back and forth in a longitudinal direction; fluid bypass passages defined at the inside of the cylinder tube to extend in the longitudinal direction; and a pair of head covers installed to ends of the cylinder tube. The head cover has a side surface provided with at least one fluid pressure inlet / outlet port, in and an end surface provided with at least two fluid pressure inlet / outlet port. Further, the head cover is provided with at least four or more fluid pressure inlet / outlet ports.

Description

technical field [0001] In particular, the present invention relates to a rodless acting cylinder in which cylinder heads installed at both ends of a cylinder barrel are interchangeable and common to each other. Background technique [0002] In recent years, rodless cylinders have been used in factories or the like as a device for conveying workpieces in various situations. Compared with rod cylinders, rodless cylinders can reduce their overall length relative to their displacement length. As a result, rodless cylinders take up less space and are easier to manage, for example enabling high-precision positioning operations. [0003] As shown in FIG. 8 , the rodless action cylinder 1 in the conventional technology includes: a cylinder barrel 2 , a slide table 3 and a pair of cylinder heads 4 , 5 . The rodless cylinder 1 has two rows of channels 8, 9 for allowing pressurized fluid to pass therethrough. The corresponding cylinder heads 4, 5 are provided with fluid pressure inl...
