Abstract: A rotary vane pump includes a housing that includes first and second plates respectively secured to first and second opposing sides of an intermediate plate. The intermediate plate includes a bore and inlet and outlet ports. The first and second sides respectively have first and second passages that are respectively in fluid communication with the inlet and outlet ports. The first and second passages are in fluid communication with the bore. The intermediate plate is reversible with respect to the first and second plates. A rotor is arranged in the bore. The rotor supports slidable vanes that are configured to pump fluid between the inlet and outlet ports.

Abstract: A leak detection module (LDM) includes a housing, a canister valve solenoid (CVS) that is arranged within the housing and in fluid communication along a first fluid passageway between first and second ports. The module also includes a pump that is arranged within the housing and is in fluid communication with the first and second ports, and a pressure sensor that is in fluid communication with at least one of the first and second ports. A first controller is arranged in the housing and is in communication with the pump, the CVS and the pressure sensor. The first controller runs a test procedure using the pump and operating the CVS between open and closed positions to monitor a pressure within the module. The first controller communicates a result based upon the monitored pressure to a second controller that is arranged outside the housing and remotely from the module.

Abstract: A leak detection module (LDM) includes a housing that provides a cavity that is enclosed by a wall that has a hole. A valve is arranged within the housing and in fluid communication along a passage that extends between first and second ports on the LDM, the valve is movable between open and closed positions. A pump is arranged within the housing and in fluid communication with the passage. A fluid fitting extends through the hole and has a passageway that extends between first and second end portions. The passageway is in fluid communication with the pump, the fluid fitting provides one of the first and second ports. A fastener secures the fluid fitting to the wall.
