To simplify operation and washing so as to ensure suction operation by enclosing one common and variable hollow chambers for a storing container chamber and a movable element for restricting an upper range, and arranging individual one way valve which is closed in the case where pressure in the hollow chamber is higher than that of a circumference, in the inlet of a common distribution pipe of each hollow chamber.
A suction pump is provided with a storing container having two chambers 1 which are arranged adjacently, upper surfaces of the chambers 1 are respectively restricted by variable elements 2 which is operated due to generate vacuum state in a common hollow chambers formed by the storing container provided with two chambers 1 and the movable element 2. When the movable element 2 is pushed and contracted by lift operation of a lever 7 which is variably held by a support part 8, an one way valve 3 formed on the upper surface of the movable element 2 is opened, and excessive pressure in the hollow chamber is reduced. The other movable element 2 arranged adjacently is expanded when pressure is reduced, suited negative pressure is generated, an one way valve 4 is opened, vacuum state is formed in a distribution pipe 8 and a suction hose 6, and suction is carried out.
