Abstract
A coupling system includes a female coupling device, the female coupling device including a first main body with a first front face, the first front face defining a first opening leading into a first fluid passageway; a stem having a stem head positioned within a sleeve; a first spring positioned about the stem that biases the sleeve into a closed position; a first seal that seals between the main body and the sleeve; a second seal that seals between the sleeve and the stem head; and a third seal that is positioned at the opening of the main body. The coupling system includes a male coupling device, the male coupling device including a second main body with a second front face, the second front face defining a second opening leading into a second fluid passageway; a valve member and a second spring positioned within the second fluid passageway; and a major seal that seals between the second main body and the valve member. The second main body of the male coupling device is capable of being inserted into the first opening of the first main body of the female coupling device so that the first seal and the third seal of the female coupling device engage the second main body of the male coupling device. The sleeve and the valve member are displaced against the first and second springs such that the second seal and the major seal are disengaged so that fluid flows through the first and second fluid passageways.
