PURPOSE:To drive a valve without employing an electrical driving means thereby to save energy, by a method wherein the valve is made ON/OFF by utilizing a reciprocating carriage. CONSTITUTION:When a carriage 100 is reciprocated in A and B directions by means of driving wires 102 and a guide rail 101, a lever 30 swings about an O- ring 40 provided on its central part. The upper end of the lever 30 reciprocates a cylinder 20 so that an inlet 12 and an outlet 13 of a valve 10 are opened and closed respectively. At this time, a permanent magnet 104 engaged with the lower end part of the lever 30 reciprocatively slides on the carriage 100, so that the ON/OFF state of the valve 10 is maintained by the attracting forces of permanent magnets 103, 105 secured on the carriage 100. |
