ABSTRACT:
The present invention is a quick coupling connector for use in connecting and disconnecting hoses adapted for conducting liquids. The connector includes a unitary molded plastic male connector body having a flow through passage extending therethrough. The body includes a guide cylinder, a lock recess adjacent to the guide cylinder, and a seating cylinder adjacent to the lock recess. The seating cylinder has an annular seal groove. An inner body O-ring is positioned in the seal groove. A unitary molded plastic female connector body having a flow through passage selectively mateably receives the male connector body. The female connector body includes a guide tube receiving the guide cylinder, a lock tube having a lock finger aperture, and a seating cylinder connected to the guide cylinder and sealingly engageable with the inner body O-ring. A mounting tube is connected to the seating tube. A tubular hose nose is mounted in the mounting tube. A locking sleeve is mounted on the mounting tube for holding a hose mounted on the hose nose. A unitary molded plastic lock ring is movably mounted on the female body having a portion engageable with the male connector body. A valve is mounted in the female connector body to control the flow of liquid through the female connector body. The valve is engageable with the male connector body to be displaced from its closed attitude to allow a liquid to flow through the female connector body.
