Abstract: A coolant distributor valve for a vehicle cooling system includes a housing that includes a valve body portion with multiple fluid ports respectively providing multiple fluid passages, a rotary valve that is arranged in the valve body portion and has multiple fluid openings, the rotary valve is configured to rotate about a valve axis between multiple flow positions arranging the multiple fluid openings relative to the multiple fluid passages. The rotary valve includes an aperture that is arranged radially inward from the multiple fluid openings, and a temperature sensor that is aligned with the aperture in each of the multiple flow positions. The temperature sensor is configured to detect a coolant temperature within the rotary valve.

Abstract: A fluid valve includes a housing that has a port wall with first and second ports, a drive assembly that has an output drive, and a compound gate valve that is arranged in the housing and includes a shaft that supports first and second gates. The shaft is operatively coupled to the output drive. The shaft has a shaft axis. The shaft is configured to rotate about the shaft axis in response to the output drive between a first position in which the first gate seals against the first port and a second position in which the second gate seals against the second port, and a location of the shaft axis is configured to remain fixed relative to the port wall during rotation of the shaft between the first and second positions.

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.

Abstract: A coolant distributor valve for a vehicle cooling system includes a housing that provides multiple ports in fluid communication with a cavity, a disc that is arranged within the cavity and configured to be rotatable about an axis, the disc includes a cam profile, and multiple valve bodies that are operatively interconnected to the cam profile. Each of the multiple valve bodies are provided at corresponding one of the multiple ports and configured to be selectively movable between open and closed positions in response to the cam profile. Any of the multiple ports have its respective valve body in the open position that is in fluid communication with the cavity, and any of the multiple ports have its respective valve body in the closed position that is fluidly blocked from the cavity.

Abstract: A method of detecting a leak in an evaporative emissions system includes sealing a system, operating a variable speed pump at a first speed to reach a first target pressure in the system, monitoring an actual pressure in the system, determining whether an error between the actual pressure and the first target pressure exceeds a threshold, and operating the variable speed pump at a second speed different than the first speed when the error exceeds the threshold to reach a second target pressure different than the first target pressure.

Abstract: A coolant distributor valve for a vehicle cooling system includes a housing that includes a shaft support housing portion that provides a monolithic, unitary structure. The shaft support housing portion has a first side opposite a second side. The first and second sides respectively include first and second bores. A valve is arranged in the housing adjacent to the first side. Electronic components are arranged in the housing adjacent to the second side. The electronic components are configured to move the valve between multiple positions. First and second seals are respectively mounted in the first and second bores. A shaft extends through and engages the seals. The shaft operatively connects the electronic components to the valve.

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 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.
