Claims

[Scope of utility model registration request]

A return spring is disposed between the rod cover of the cylinder body and the piston to urge the piston toward the head cover, and the head cover is provided with an import port, an exhaust port, and a valve chamber that communicates these ports. A poppet valve holding a permanent magnet is fitted into the chamber so that it can slide within a predetermined stroke range that is shorter than the stroke of the piston, and the tip of the piston moves into the valve chamber as it slides. A plunger is provided protruding to enter and exit the valve, and this plunger is provided with a passage that communicates the head side chamber in the cylinder body with the valve chamber, and a valve opening is formed at the tip of this passage, so that the tip of the plunger is connected to the valve chamber. When the plunger enters the room and is attracted to the permanent magnet, the poppet valve closes the valve opening, cutting off the connection between the import and exhaust ports, and the tip of the plunger retracts from the valve chamber and separates from the permanent magnet. The automatic reciprocating cylinder is characterized in that the valve port is opened so that communication between the import port and the exhaust port is opened.
