Abstract

A valve assembly comprises at least one multiple valve having a duct module which includes at least one elongated fluid duct which extends in a straight line along a longitudinal direction and a plurality of branch ducts which open in openings in the fluid duct which are arranged side by side along the longitudinal direction in the inner wall of the fluid duct. The multiple valve comprises at least one multiple valve core which is inserted into the fluid duct such that each valve seal can seal one of the openings. The multiple valve core comprises an elongated carrier and at least one valve element, the carrier having at least one support portion for abutment against the inner wall of the fluid duct and at least one receiving area in which the valve element is connected to the carrier so as to be non-displaceable in the longitudinal direction of the carrier. A plurality of valve seals for closing the openings which are provided on one or on a plurality of valve elements is provided, the valve seals being arranged successively in the longitudinal direction of the carrier and being movable in a closing direction perpendicular to the longitudinal direction. The duct module forms part of a basic module on which a plurality of valve modules fluidically connected to the branch ducts can be mounted, the valve modules being in particular configured so as to be adapted to actuate pressure pieces in the branch ducts which cooperate with the valve seals of the valves of the multiple valve to permanently open the respective valve.

First claim

The invention claimed is:

1. A multiple valve core for insertion into an elongated fluid duct which extends in a straight line along a longitudinal direction and which includes an inner wall having a plurality of openings arranged side by side along the longitudinal direction, comprising an elongated carrier and at least one valve element, the carrier having at least one support portion for abutment against the inner wall of the fluid duct and at least one receiving area in which the valve element is connected to the carrier so as to be non-displaceable with respect to the carrier at least in the longitudinal direction thereof, a plurality of valve seals for closing the openings being provided which are provided on one or on a plurality of valve elements, the valve seals being arranged successively in the longitudinal direction of the carrier and being movable in a direction perpendicular to the longitudinal direction.

2. The multiple valve core of claim 1 wherein two support portions are provided which are arranged substantially parallel to each other, the receiving area being located between the support portions and extending perpendicularly thereto.

3. The multiple valve core of claim 1 wherein at least one valve element is provided on which a plurality of valve seals is arranged.

4. The multiple valve core of claim 3 wherein a single valve element is provided on which all valve seals are arranged.

5. The multiple valve core of claim 3 wherein the valve element is plate-shaped and, as seen in the longitudinal direction rests on the receiving area between the valve seals.

6. The multiple valve core of claim 3 wherein at least one of the valve seals is delimited by a particularly linear recess in the valve element.

7. The multiple valve core of claim 1 wherein the carrier has an interlocking fit structure which cooperates with the valve element and prevents the valve element from moving in the longitudinal direction with respect to the carrier, in particular the interlocking fit structure comprising at least one projection in the receiving area which is arranged so as to block a displacement of the valve element in the longitudinal direction.

8. The multiple valve core of claim 1 wherein the carrier extends on its long sides perpendicularly to the receiving area at least up to an upper side of the valve element.

9. The multiple valve core of claim 1 wherein stops which limit a movement of the valve seals perpendicularly to the longitudinal direction towards the interior of the fluid duct are formed in the receiving area.

10. The multiple valve core of claim 1 wherein the receiving area has several apertures in the carrier which are separated from each other and in which one respective valve element is inserted which has a single valve seal.

11. The multiple valve core of claim 10 wherein the valve element, in addition to the valve seal, comprises a tappet guided in the carrier and connected with the valve seal and a spring element arranged between the receiving area and the valve seal.

12. The multiple valve core of claim 1 wherein the receiving area is formed such that a plurality of apertures with which a respective valve seal is associated is provided successively in the longitudinal direction, in particular rigid portions being provided on the carrier between adjacent valve seals on which the valve element is in contact with the carrier.

13. The multiple valve core of claim 1 wherein valves seals are arranged in different positions in the peripheral direction about the longitudinal direction.

14. A multiple valve comprising a duct module having at least one elongated fluid duct which extends in a straight line along a longitudinal direction and a plurality of branch ducts which open into openings in the fluid duct which are arranged side by side along the longitudinal direction in the inner wall of the fluid duct, and comprising at least one multiple valve core according to any of the preceding claims, which is inserted into the fluid duct such that each valve seal can seal one of the openings.

15. The multiple valve of claim 14 wherein the inner wall of the fluid duct forms a valve seat for the respective associated valve seal about the edge of the opening.

16. The multiple valve of claim 14 wherein the individual valves are configured as check valves which enable a fluid flow through the branch duct into the fluid duct or block it in the opposite direction.

17. The multiple valve of claim 14 wherein pressure pieces are arranged in the branch ducts which are adapted to be actuated by the outlet of the respective branch duct opposite the fluid duct and which cooperate with the valve seals and can urge the latter towards the interior of the fluid duct to open the appropriate valve of the multiple valve.

18. A valve assembly having at least one multiple valve of claim 14 , the duct module being part of a basic module on which a plurality of valve modules which are fluidically connected with the branch ducts can be mounted, the valve modules being in particular configured such that they are adapted to actuate pressure pieces in the branch ducts cooperating with the valve seals of the valves of the multiple valve in order to permanently open the respective valve.
