Abstract
A cap and shield assembly for a fluid conduit coupler has a shield and a cap hingedly connected to the shield with a shaft having a cross-pin extending therethrough. A cam bushing in the bore of the shield has a cam surface which coacts with the cross-pin to provide a positive closed position for the cap relative to the shield. Preferably, the cam bushing also provides a positive open position. The cap and shield assembly is particularly advantageous for couplers having a dry-break interface because the cap is readily moved between open and closed positions and operators will be more inclined to use the cap after fluid transfer. Shrouds on the cap and the shield coact to protect the coupler interface when the cap is in the closed position thereby protecting the dry-break interface from contamination by road and environmental debris. This is particularly advantageous compared to the dust cap of the prior art which tends not to be used for its intended purpose of protecting the fluid conduit coupler.
