Fluid coupling seal
First Claim
1. A fluid coupling including an elongate female section with front and rear ends, a central longitudinal flow passage, a socket with a cylindrical bore and a flat radial rearwardly disposed annular seat entering the rear end concentric with the bore;
- an annular resilient sealing ring with flat radially extending front and rear surfaces;
a substantially cylindrical inner side and a cylindrical outer side;
said ring is positioned in the socket with its front surface in flat engagement on said seat and its outer side engaging said bore;
an elongate male section with front and rear ends, a central longitudinal flow passage, a cylindrical front end portion slidably engaged in the socket and a flat radially extending, forwardly disposed annular sealing face at the forward end of said cylindrical portion and establishing flat engagement with the rear surface of the ring; and
mechanical means engaged with and between the sections, and urging and holding the male section forwardly relative to the female section with said ring clamped tight between the seat and the face; and
retaining means to retain the ring in the socket and including a plurality of circumferentially spaced longitudinally extending, radially inwardly projecting ribs on said bore and about which adjacent portions of the ring flow and establish tight contact.

Abstract
A fluid coupling including an elongate female section with front and rear ends, a central flow passage, means to connect the front end with a fluid conductor and a central cylindrical socket entering its rear end and defining a flat bottom; an annular sealing ring positioned in the socket adjacent said bottom; an elongate male section with front and rear ends, a central flow passge and means at its rear end to connect with a fluid conductor; the male section is slidably engaged with the socket in the female section with its front end engaging said seal; a mechanical means is provided to hold the male section forwardly in and relative to the female section with said ring clamped tight between said bottom and front end of the male section; the coupling includes means to retain the ring in the socket and including a plurality of circumferentially spaced longitudinally extending, radially inwardly projecting ring engaging ribs in the socket and about which adjacent portions of the ring flow to establish conformed tight retaining contact therewith.
