Valve body for a valve of a coolant system, valve having such a valve body, and manufacturing method

1 . A valve body for a valve of a coolant system, comprising:

at least one tubular through channel for a coolant; and

a base body configured to be rotatable about an axis of rotation by a drive and having a contact surface for abutting against a sealing arrangement of a valve housing of the valve with at least two sealing portions and at least two sliding portions which lie on a spherical enveloping surface,

wherein the base body is divided by an equatorial plane arranged orthogonally to the axis of rotation,

wherein the base body comprises an opening arranged parallel to the equatorial plane, and

wherein the opening is closed by a cover such that the at least one tubular through channel is formed tubular by the base body and the cover.

2 . The valve body according to claim 1 , wherein

the at least one tubular through channel has a uniform cross-sectional diameter.

3 . The valve body according to claim 1 ,

wherein the cover is connected to the base body in an integrally bonded and/or form-fitting manner.

4 . The valve body according to claim 3 , wherein the cover is connected to the base body in the integrally bonded and/or form-fitting manner by welding or clipping.

5 . The valve body according to claim 1 ,

wherein the base body has a partition wall extending along an axis of rotation of a drive shaft and dividing the base body into two valve halves, wherein a through channel is formed in each valve half.

6 . The valve body according to claim 5 ,

wherein the cover has a flow-guiding contour with two parallel legs, between which a gap for receiving the partition wall extends.

7 . The valve body according to claim 6 ,

wherein the flow-guiding contour of the cover has a curved inner surface which merges flush into a curved inner surface of a flow-guiding contour of the base body and delimits the at least one tubular through channel.

8 . The valve body according to claim 1 ,

wherein the at least two sliding portions of the contact surface are each subdivided by a separating ridge extending parallel to the axis of rotation.

9 . The valve body according to claim 8 ,

wherein the separating ridge is arranged so as to be completely countersunk in a groove.

10 . The valve body according to claim 1 ,

wherein each one of the at least two sealing portions extends in a circular manner around a respective access opening of one of the at least one tubular through channel.

11 . A method for manufacturing the valve body according to claim 1 , wherein the base body and the cover are each shaped by an injection-moulding process and are subsequently connected to one another.

12 . The method according to claim 11 , wherein the cover is connected to the base body by welding or by clipping.

13 . The method according to claim 12 , wherein the cover is connected to the base body by hot gas welding, ultrasonic welding or laser welding.

14 . A valve body for a valve of a coolant system, comprising:

at least one tubular through channel for a coolant; and

a base body configured to be rotatable about an axis of rotation by a drive and having a contact surface for abutting against a sealing arrangement of a valve housing of the valve with at least two sealing portions and at least two sliding portions which lie on a spherical enveloping surface,

wherein the base body is divided by an equatorial plane arranged orthogonally to the axis of rotation,

wherein the base body comprises an opening arranged parallel to the equatorial plane and closed by a cover, wherein the at least one tubular through channel is formed by the base body and the cover, and

wherein the at least two sliding portions have a height which is smaller than a diameter of the sealing portions, such that the coolant can flow over the base body during a switching operation of the valve.
