Abstract: A flat face female hydraulic coupling includes: a body with a continuous passage extending in an axial direction; a valve stem coaxially arranged in the continuous passage of the body; a valve guide coaxially arranged in the continuous passage of the body, the valve guide being sealed against a surface of the continuous passage, the valve guide including a central passage; and a valve sleeve arranged slidingly in the axial direction between a first position and a second position, the valve sleeve being guided by the valve guide, the valve sleeve being sealed to the valve guide in both the first position and the second position and sealed to the valve stem in the first position, a passage being provided between the valve stem and the valve sleeve in the second position. In the first position of the valve sleeve a fluid chamber is formed.
