Claims

[Claims for Utility Model Registration] (1) A fluid pressure cylinder comprising a cylinder body that reciprocably houses a piston, a piston rod whose one end is connected to the piston, and a fluid supply port formed in the cylinder body. In addition, magnets are arranged at both ends of the cylinder body, and magnets are arranged at both ends of the reciprocating piston so that the same polarity as the magnets arranged at both ends of the cylinder body face each other. Features a high-speed fluid pressure cylinder. (2) A shedding device for selectively changing warp yarns to be shedding by raising and lowering a heald frame according to a weaving pattern, characterized in that the shedding device has the following configurations a to c. (a) equipped with fluid supply ports for raising and lowering;
In addition, magnets are disposed at both ends of the cylinder body, and magnets are disposed at both ends of the piston so that the same polarities as the above magnets face each other, and the cylinder body side and piston rod side are connected to the machine base side or the heald frame side, respectively. (b) a solenoid valve that controls the supply of fluid to the fluid supply port of the high-speed fluid pressure cylinder; (c) A shedding device for a loom, comprising a control device that controls the electromagnetic valve based on data related to a weaving pattern stored in advance.
