Abstract: A vane pump includes a housing that provides a bore in fluid communication with an inlet passageway and an outlet passageway, and a rotary assembly that is arranged within and configured to rotate relative to the bore. The rotary assembly includes a rotor that is mounted to a shaft and has multiple slots. The rotor has a first and second faces that engage the housing. A vane is received in each of the slots, each vane has first and second surfaces that extend a length in a longitudinal direction from a first end portion to a second end portion. The first end portion is received in its respective slots. The rotary assembly includes a recess on at least one of the first face, the second face, the first surface of the first portion, and the second surface of the first portion.

Abstract: A fluid valve includes a housing (70) that includes a first housing portion (76) that provides fluid passage that has an inlet port (72.74) and an outlet port (72, 74) that are configured to be in fluid communication with one another. The housing has a second housing portion (78) that is affixed to the first housing portion. The fluid valve further includes a solenoid (88) that is arranged within the first housing portion (76) and has a plunger (94) that is movable between open and closed positions to selectively fluidly connect the inlet and outlet ports. The fluid valve further includes a Hall effect sensor (102) that is arranged in the second housing portion (78) and is aligned with the plunger (94) in one of the opened and closed positions.

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.
