Abstract

The invention relates to a valve for fitting to a to a container, in particular a bottle, in which a pressure has accrued, comprising a valve housing (1) in which at least one valve seat (23, 24) is provided. A valve seat (23, 24), independent of the bottle pressure is located between a piston (28) and the bottle contents and connected to said piston (38), whereby the other side of said piston (28) is pressurised by an energy store (39), the force of which is adjustable. A valve for fitting to a container, in particular a bottle, in which a pressure has accrued, comprising a valve housing in which at least one valve seat is provided. A valve seat, independent of the bottle pressure is located between a piston and the bottle contents and connected to the piston, whereby the other side of the piston is pressurized by an energy store, the force of which is adjustable.

Claims

1. A valve for placing onto a container, in particular onto a cylinder in which a pressure is built up, having a valve housing (1) in which at least one valve seat (23, 24) is provided, characterized in that a valve seat (23, 24) which is independent of the cylinder pressure is situated between a piston (28) and the cylinder contents connected to the piston (28), a force accumulator (39) which can be changed in its force pressing on the piston (28) on the other side.

2. The valve seat as claimed in claim 1, characterized in that the valve seat is formed by a valve cone (23) which sits in a hole opening (24) of the valve housing (1).

3. The valve as claimed in claim 2, characterized in that the valve cone (23) is supported against a force accumulator (22) in a guide housing (15) which is inserted into the valve housing (1).

4. The valve as claimed in claim 2 or 3, characterized in that the valve cone (23) is placed on a ram (19) which is optionally surrounded by a helical spring (22) as the force accumulator and which slides in an O-ring (20) which has the same inside diameter as the hole opening (24).

5. The valve as claimed in claim 3 or 4, characterized in that the guide housing (15) has at least one opening (17) to the interior of the cylinder.

6. The valve as claimed in claim 5, characterized in that the opening (17) is covered by a filter (18).

7. The valve as claimed in at least one of claims 2-6, characterized in that the valve cone (23) is connected via a further ram (31) to a thrust-transmitting component (30) which slides in the piston (28).

8. The valve as claimed in claim 7, characterized in that the thrust-transmitting component (30) closes an oblique hole (32) which is connected to a relief hole (33) in the valve housing (1) or to a spring housing (34).

9. The valve as claimed in at least one of claims 1-8, characterized in that the piston (28) slides in a cylinder space (27) in the valve housing (1).

10. The valve as claimed in claim 9, characterized in that the cylinder space (27) is closed by the spring housing (34).

11. The valve as claimed in claim 10, characterized in that the spring housing (34) has an axial stepped hole (35) in which, in particular, the force accumulator (39) which can be changed in its force is held.

12. The valve as claimed in claim 11, characterized in that the force accumulator (39), as a helical spring, encompasses an intermediate component (36) and is supported at one end against a head (37) of the intermediate component (36) and at the other end against the piston (28).

13. The valve as claimed in claim 11, characterized in that an actuating pin (48) is inserted into the head (37) of the intermediate component (36).

14. The valve as claimed in claim 13, characterized in that the actuating pin (48) encloses, in the intermediate component (36), a valve space (44) in which a nonreturn valve (45, 46) is situated.

15. The valve as claimed in claim 14, characterized in that a compression spring (46) is supported in the valve space (44) against a nonreturn-valve cone (45) which closes a hole (42) in the intermediate component (36).

16. The valve as claimed in claim 15, characterized in that the intermediate component (36) slides in a sealed manner in an annular space (41) which is formed by an annular wall (40) protruding from the piston (28).

17. The valve as claimed in claim 16, characterized in that the hole (42) leads from the nonreturn valve into the annular space (41) and also into an oblique hole (49) which connects the annular space (41) to a piston space (26) into which the hole (25), which forms the valve seat (24) with the valve cone (23), also leads.

18. The valve as claimed in at least one of claims 1-17, characterized in that a filling valve is also provided in the valve housing (1).

19. The valve as claimed in claim 18, characterized in that the filling valve is designed as a nonreturn valve (7).
