Abstract

PURPOSE:To prevent water or waste from being sucked in a piston bar by enlarging the diameter of the upper end opening of a pump cylinder than that of the piston bar, while forming a gap capable of sliding and air ventilation. CONSTITUTION:When a piston bar 2 moves upward, a ring valve 5 is slid downward along the inner peripheral surface of a pump cylinder 3 inside a valve groove 6. The outer periphery of the ring valve 5 is press-fitted on the peripheral surface of the inner wall of the pump cylinder 3 to keep airtightness against the pump cylinder 3, so that air in a vessel 10 is absorbed. When the piston bar 2 moves downward, the ring valve 5 is slid upward conversely, and the air in the pump cylinder 3 is communicated from an air ventilation groove 8 through an air ventilation passage 7. The air is then discharged from a gap 9 outside a manually handled vacuum pump (a). It is thus possible to prevent water or waste from being sucked in the piston bar.

A valve seat is provided, and a valve groove into which an O-ring type ring valve is fitted is provided on the valve seat. The ring valve is slightly wider than the ring valve, and the valve groove is slightly wider than the ring valve. An air bleed passage is formed by cutting out to the depth of the groove bottom, an air bleed groove is formed at the bottom of the valve groove in communication with this air bleed passage, and the diameter of the upper end opening of the pump cylinder is made slightly larger than the diameter of the piston rod. A hand-operated vacuum pump for reducing pressure inside a container, characterized by forming a gap that allows sliding and air removal.
