A part-turn valve comprises a valve housing 2 with a passage 3 and, located therein, a valve member which, by means of a lever 6, can be rotated between two end positions corresponding to the valve being open and closed. To achieve delayed closing and opening of the valve 1, there is between the two end positions at least one lock 9 which can be overcome and which, in the locked position, prevents pivoting of the lever 6. The lever 6 comprises a casing 13 which is slidably displaceably arranged on a lever 12 and spring-loaded in the direction away from the valve 1. <IMAGE> |
