Vapor coupler

A fluid system coupler, comprising:

• a coupler body at least partially defining a fluid passageway therethrough, the coupler body having an open end configured to selectively receive an adaptor therein and one or more slots extending through the coupler body adjacent to the open end;
• a seal assembly disposed within the coupler body and movable between a first position and a second position, the seal assembly having one or more central openings to allow fluid or vapor to flow through the seal assembly, the seal assembly having one or more wings that extend through the one or more slots to an exterior in the coupler body;
• one or more lever cams that are pivotally connected to the coupler body, the one or more lever cams being movable between a locked position and an unlocked position, a portion of the one or more lever cams extending through the one or more slots in the coupler body to engage the adaptor when the one or more lever cams are in the locked position, and the one or more lever cams being at least partially withdrawn from the one or more slots to disengage the adaptor when the one or more lever cams are in the unlocked position;
• and
• a handle movable connected to the coupler body and to the wings of the seal assembly, the handle being movable between a first position and a second position, movement of the handle from the first position to the second position moves the seal assembly from the first position to the second position and enables the one or more lever cams to move to the unlocked position, and movement of the handle from the second position to the first position moves the seal assembly from the second position to the first position and moves the one or more lever cams to the locked position.

A fluid system coupler, comprising:

• a coupler body at least partially defining a fluid passageway therethrough, the coupler body having an open end configured to selectively receive an adaptor therein,
• a seal assembly movably disposed within the coupler body, the seal assembly comprising a collar, an adaptor seal mounted on a first end of the collar, and a seal mounted on a second end of the collar, the adaptor seal being configured to sealingly engage an end of an adaptor received within the coupler body;
• a poppet assembly movably mounted to the seal assembly, the poppet assembly comprising a seal plate that is movable between an open configuration and a closed configuration, the seal plate sealingly engaging the seal mounted on the second end of the collar in the closed configuration;
• and
• a handle movably connected to the coupler body, the handle being operatively associated with the seal assembly such that movement of the handle moves the seal assembly relative to the coupler body.
