PROBLEM TO BE SOLVED: To enable a vessel eliminator to correspond to a high speed line in an air cylinder mode by means of one solenoid valve alone. SOLUTION: In this device, a push plate 9 is installed in the tip of a piston rod 8a of an air cylinder 1, energizing a solenoid valve 4 as long as the specified time, and a vessel is extruded onto a conveyor for elimination. In this case, this one solenoid valve 4 is provided with each spot of pressure source connecting ports and exhaust ports and two air cylinder connecting ports, whereby the side restoring a piston 8 of the air cylinder 1 is usually pressurized without passing through the solenoid value 4, and when this valve 4 is excited, the side restoring the piston 8 is pressurized and at the same time the side restoring the piston 8 is exhausted, and thereby when it is demagnetized, the side extruding the piston 8 is exhausted and simultaneously any exhaust on the side restoring the piston 8 is made to be closed.
