Abstract

PURPOSE: To prevent breakage of a pump by installing a leak valve whose leak hole is closed by a valve, on the discharge side of a valve fixing plate, and allowing leak to be generated automatically under a prescribed pressure or above when the discharge side of the pump is closed in pump driving.
CONSTITUTION: When a magnet 4 moves right and left on an AC electromagent, a driving plate 3 moves right and left and operates a rubber valve 1 fixed on a valve body 6. When the rubber valve 1 moves rightward, the air which is introduced from the air introducing part 7 pushes-up the valve of the valve part 8 and enters into the rubber valve 1. When the rubber valve 1 moves leftward, the air inside is pushed- out, and the valve 8 is closed, and a valve 9 is opened, and the air inside passes through a valve 9 and jets from a discharge opening 10. A vlave 13 whose leak hole 17 is closed by a valve 16 is installed on the discharge side of a valve fixing plate 12, and if the air pressure in the rubber valve 1 reaches a prescribed value or above, when the discharge side of the pump is closed air pushes-up the valve 16 and leaks out, and breakage of the valve part is prevented.
