Abstract
A hydro-pneumatic pressure vessel includes a container unit, a connector unit and a protecting unit. The container unit includes an elastic diaphragm dividing an inner space of the container unit into a water chamber and an air chamber. The connector unit includes a water fitting connected to the container unit and formed with a water port. The protecting unit includes a protecting member and a resilient connecting member interconnecting the water fitting and the protecting member. The protecting member is movable from an open position to a blocked position for blocking the water port so as to prevent the diaphragm from being squeezed by an air pressure of the air chamber into the water port.
Claims10
A hydro-pneumatic pressure vessel comprising:
- a container unit including an elastic diaphragm that divides an inner space of said container unit into a water chamber and an air chamber;
- a connector unit including a water fitting that is connected to said container unit and that is formed with a water port communicating fluidly with said water chamber;
- and
- a protecting unit including a protecting member that is disposed in said water chamber and that has a size larger than that of said water port, and a resilient connecting member that interconnects said water fitting and said protecting member, said protecting member being movable resiliently between an open position, where said water chamber is filled with water and where said protecting member is away from said water port, and a blocked position, where the water flows out of said water chamber, where said resilient connecting member is compressed resiliently and where said protecting member blocks said water port so as to prevent said diaphragm from being squeezed by an air pressure of said air chamber into said water port.
