Abstract

A fluid coupling containing two coupling halves coupled to one another via connecting elements. Each of the coupling halves containing a housing which has an end face. The end face having at least one connecting element for the mutual connection of the coupling halves. The housing having connecting faces of the two coupling halves contacting one another when in the coupled state. A spherical valve element and a locking element, which can be mutually operated via the connecting elements and releases a rotary lever for operating the valve element.

Claims (11)

1 . Fluid coupling comprising two coupling halves configured to be coupled to one another in a vertical direction via connecting elements, each of the coupling halves containing: a housing, which has an end face, the end face having at least one connecting element for the mutual connection of the coupling halves, the housing having an end-face connecting face, the connecting faces of the two coupling halves contacting one another when in the coupled state; a spherical valve element; a locking element, which is configured to be mutually operated via the connecting elements and releases rotary levers; and a rotary lever for operating the valve element, wherein the locking element is configured in the housing such that it is displaced parallel to the throughflow direction or longitudinal axis to release the rotary element when the coupling halves are hooked into one another vertically relative to the through flow direction or longitudinal axis.

2 . Fluid coupling according to claim 1 , wherein the connecting element is configured to be hooked into a flange projection of the opposing coupling half in order to connect the coupling halves.

3 . Fluid coupling according to claim 1 , wherein the connecting element is designed as a half-shell.

4 . Fluid coupling according to claim 3 , wherein the half-shell-shaped connecting element has a wrap angle of 150-180°.

5 . Fluid coupling according to claim 3 , wherein the half-shell-shaped connecting element extends along the edge of one half of the end face.

6 . Fluid coupling according to claim 1 , wherein the connecting element has a sliding face running obliquely or in an inclined manner to the vertical and acts therewith on a sliding face on the locking element in order to displace the locking element parallel to the throughflow direction or longitudinal axis.

7 . Fluid coupling according to claim 1 , wherein a vertical hooking-in process of the two coupling halves triggers an unlocking process, which is horizontal or parallel to the longitudinal axis, of the locking elements and releases the rotary levers.

8 . Fluid coupling according to claim 1 , wherein the connecting element is configured to be hooked into the locking element.

9 . Fluid coupling according claim 1 , wherein a displaceable actuation element is arranged in the rotary lever, wherein the actuation element is configured to be operated by means of the locking element.

10 . Fluid coupling according claim 1 , wherein a catch system is arranged on the housing in order to lock the rotary lever in place.

11 . Fluid coupling according to claim 10 , wherein the catch system is formed by at least one recess in the housing, into which recess the actuation element engages.
