Valve for closing a container, container and a system and method for filling container
First Claim
1. A valve for closing a container and for enabling the container to be filled, said valve comprising a housing with an inlet port and an outlet port wherein said inlet port is adapted for connection to a fluid source, said connection being selected from the group of indirect and direct connections, and wherein said outlet port is adapted for connection to said container said connection being selected from the group of indirect and direct connections;
- a closing member;
and at least one valve member which in a first position allows fluid communication between said inlet port and said outlet port and which, in a second position, prevents fluid communication from said inlet port to said outlet port, wherein said valve member is brought into and maintained in said first position only if a static pressure difference across said valve member is below a pre-determinable first threshold.

Abstract
A valve for closing a container and for enabling the container to be filled has a housing (20) with an inlet port (30) and an outlet port (40). A closing member (60) is provided for sealingly closing the valve at the inlet port (30). At least one valve member (70) is provided for controlling fluid communication between the inlet port (30) and the outlet port (40). The valve member only allows fluid communication when it is in a first position. The valve member (70) is designed in such a way that it is brought into and maintained in said first position only if a predetermined filling condition is achieved. The filling condition is typically achieved, when the filling pressure of a system for filling the container (50) is initially below a first predetermined or predeterminable threshold value.

11. A system for filling a container with a fluid exclusively from an authorised fluid source, comprising a pressure regulating means in fluid communication to said fluid source and adapted for connection with a valve on said container, said valve comprising
a housing with an inlet port and an outlet port wherein said inlet port is adapted for direct or indirect connection to a fluid source and wherein said outlet port is adapted for direct or indirect connection to said container; -
a closing member;
and at least one valve member which in a first position allows fluid communication between said inlet port and said outlet port and which, in a second position, prevents fluid communication from said inlet port to said outlet port, wherein said valve member is brought into and maintained in said first position only if a static pressure difference across said valve member is below a pre-determinable first threshold;
wherein said pressure regulating means is designed to maintain the pressure of the fluid supplied to said container below a pre-determined or pre-determinable first threshold selected in such a way that said valve member of said valve is brought into and maintained in said first position. - View Dependent Claims (12, 13, 14, 15, 16)

17. A refillable container for storing fluids, wherein said container is provided with a valve, said valve comprising
a housing with an inlet port and an outlet port wherein said inlet port is adapted for direct or indirect connection to a fluid source and wherein said outlet port is adapted for direct or indirect connection to said container; -
a closing member;
and at least one valve member which in a first position allows fluid communication between said inlet port and said outlet port and which, in a second position, prevents fluid communication from said inlet port to said outlet port, wherein said valve member is brought into and maintained in said first position only if a static pressure difference across said valve member is below a pre-determinable first threshold. - View Dependent Claims (18)

19. A method for filling a container having a valve with a fluid from a fluid source, said valve comprising
a housing with an inlet port and an outlet port wherein said inlet port is adapted for direct or indirect connection to a fluid source and wherein said outlet port is adapted for direct or indirect connection to said container; -
a closing member;
and at least one valve member which in a first position allows fluid communication between said inlet port and said outlet port and which, in a second position, prevents fluid communication from said inlet port to said outlet port, wherein said valve member is brought into and maintained in said first position only if a static pressure difference across said valve member is below a pre-determinable first threshold;
the method comprising the steps of;
a) connecting the valve X to said fluid source b) controlling the delivery pressure of said fluid at said inlet port of said valve such as to maintain the static pressure difference across a valve member of said valve below a predetermined or predeterminable first threshold. - View Dependent Claims (20, 21, 22, 23)
