A rotary valve type quick coupling for interconnection of two pressure medium conduits, comprising on one hand a coupling unit (10) having a longitudinal communication passage (21) and a rotary valve element (18) which is formed with a diametrically extending bore (27), and on the other hand a tube shaped connector nipple (12) having an inlet end (35, 36) and an outlet end (13), of which the inlet end (35, 36) is receivable in the diametrically extending bore (27) in the valve element (18) for interconnection of the coupling unit (10) and the connector nipple (12). The inner diameter of the inlet end (35, 36) of the connector nipple (12) is equeal to or smaller than the diameter of the communication passage (21) of the coupling unit (10), and the outlet end (13) of the connector nipple (12) comprises a diverging, pressure recovering outlet portion (40). |
