Abstract: Many devices, such as a turbocharger, use an apparatus to control their functions. For example, pneumatic and electric actuators are used to provide positional control of a mechanism on the turbocharger. The actuator must connect to the vehicles electrical system to provide suitable communication and control of the actuator. They must also have internal control and interconnection of devices such as sensors, electronic control unit, external electrical connector, and internal electrical connections. The electrical connections, placement of sensor, and placement of the controller are critical to the performance, reliability, and cost of the actuator. The control and interconnection system will provide the aforementioned requirements including a “quick connect” capability for electrical connections and ease of assembly.

Abstract: An exhaust gas recirculation (EGR) arrangement having an intake manifold with a valve base assembly integrated with the engine's intake manifold. The valve base assembly has a valve seat positioned in the path of fluid flow through the valve base. A valve member is also contained in the valve base and is operably disposed in relation to the valve seat. An actuator is connectable with the valve base and with the valve member to open and close the valve seat in response to actuation of the actuator. The actuator can disconnect from the valve base and valve member.

Abstract: An anti-coking valve arrangement having a valve body that defines a passage for the flow of fluid medium. Valve seat and valve member positioned within the valve body and function to control the flow of fluid medium. A first anti-coking device is operably associated with the valve stem. A second anti-coking device is operably associated with the bearing guide member. A third anti-coking device is operably associated with the valve member and the valve seat. A fourth anti-coking device is operably associated with the valve stem and the bearing guide. A fifth anti-coking device is operably associated with the bearing guide. A sixth anti-coking device is operably associated between the valve stem and the bearing guide.

Abstract: An assembly for testing an evaporative emission control system of an automotive vehicle which controls emission of volatile fuel vapors. The assembly is used to determine if a leak is present in a portion of the system which includes a vapor collection canister. The leak detection assembly incorporates a vacuum actuated canister vent control valve which seals the evaporative system so the leak detection test can be performed. A vacuum actuated pump which performs a leak detection test. An engine control unit initializes the pump by drawing air into a pump cavity and also closes the vent control valve. After the initialization period, the pump is activated to pressurize the evaporative emission control system. Once a control pressure is achieved, the cycle rate starts to drop off. If no leak exists in the system, the pump will eventually stop pumping. If there is a leak, the pump will continue to pump at a rate that will be representative of the flow characteristics of the size of the leak.
