Abstract

A valve includes a longitudinally movable valve body that is arranged in the valve, wherein the valve housing has at least two guide grooves, with which auxiliary guide elements, arranged on the valve body, engage an exterior surface of the valve housing. The guide grooves of the valve housing are shaped such that they define a combined translatory and rotary movement path of the valve body with the aid of the auxiliary guide elements in order to open or close the valve.

First claim

What is claimed is:

1. A valve comprising:
a valve housing and a longitudinally movable valve body arranged in the valve housing,
wherein the valve housing has at least two guide grooves, with which auxiliary guide elements, arranged on the valve body, engage on an exterior surface of the valve housing,
wherein the guide grooves are shaped to define a combined translatory and rotary movement path of the valve body and the auxiliary guide elements when the valve body is moved to open or close the valve,
wherein the valve body has a valve inlet and an opposed valve outlet, each continuously open, and a through bore continuously open from the valve inlet to the valve outlet, and
wherein the valve body has additional auxiliary guide elements, which engage with the guide grooves on an interior surface of the valve housing, and which are arranged opposite the auxiliary guide elements engaging the valve housing on the exterior surface.

2. The valve as claimed in claim 1 , wherein the additional auxiliary guide elements each have a nub shape.

3. The valve as claimed in claim 1 , wherein the valve housing has reinforced material regions in areas around the guide grooves.

4. The valve as claimed in claim 1 , wherein the auxiliary guide elements are fixedly arranged on the valve body at least on a side proximate the valve outlet.

5. The valve as claimed in claim 4 , wherein the fixed arrangement between the auxiliary guide elements and the valve body is a welded connection, a screw connection, a clip connection or a positive locking connection.

6. The valve as claimed in claim 1 , wherein the valve body includes a valve chamber, which is sealed from an ambient atmosphere by two seals when the valve is closed.

7. The valve as claimed in claim 6 , wherein the seals are multi-component injection molded parts formed on the valve body.

8. The valve as claimed in claim 1 , wherein the valve is made of a plastic material.

9. The valve as claimed in claim 1 , wherein the valve is configured to produce a radial flow against the valve body.

10. The valve as claimed in claim 1 , wherein the valve is designed as a disposable product.

11. The valve as claimed in claim 1 , wherein the guide grooves are formed as slots extending from the exterior surface to an interior surface of the valve housing.

12. The valve as claimed in claim 1 , wherein the auxiliary guide elements are arranged on an exterior surface of the valve body, and engage with the guide grooves from outside the valve housing.

13. A valve comprising:
a valve housing and a longitudinally movable valve body arranged in the valve housing,
wherein the valve housing has at least two guide grooves, with which auxiliary guide elements, arranged on the valve body, engage on an exterior surface of the valve housing,
wherein the guide grooves are shaped to define a combined translatory and rotary movement path of the valve body and the auxiliary guide elements when the valve body is moved to open or close the valve,
wherein the valve body has a valve inlet and a valve outlet coaxial with the valve inlet, each continuously open, and a through bore continuously open from the valve inlet to the valve outlet, and
wherein the auxiliary guide elements consist of three distinct elements.

14. A valve comprising:
a valve housing and a longitudinally movable valve body arranged in the valve housing,
wherein the valve housing has at least two guide grooves, with which auxiliary guide elements, arranged on the valve body, engage on an exterior surface of the valve housing,
wherein the guide grooves are shaped to define a combined translatory and rotary movement path of the valve body and the auxiliary guide elements when the valve body is moved to open or close the valve,
wherein the valve body has a continuous open bore, and
wherein the valve body has additional auxiliary guide elements, which engage with the guide grooves on an interior surface of the valve housing, and which are arranged opposite the auxiliary guide elements engaging the valve housing on the exterior surface.

15. The valve as claimed in claim 14 , wherein the additional auxiliary guide elements each have a nub shape.

16. A valve comprising:
a valve housing and a longitudinally movable valve body arranged in the valve housing,
wherein the valve housing has at least two guide grooves, with which auxiliary guide elements, arranged on the valve body, engage on an exterior surface of the valve housing,
wherein the guide grooves are shaped to define a combined translatory and rotary movement path of the valve body and the auxiliary guide elements when the valve body is moved to open or close the valve,
wherein the valve body has a longitudinal axis, first and second longitudinally opposed end faces, and a through bore continuously open from the first end face to the second end face,
wherein the second end face includes a continuously open valve outlet and the first end face includes a continuously open valve inlet axially aligned with the valve outlet along the longitudinal axis of the valve body, and
wherein the auxiliary guide elements consist of three distinct elements.
