Abstract: An injection pressure sensor (10) intended for use with a fluid source (12). The injection pressure sensor (10) has a sensor element (14) in communication with the fluid source (12) and in communication with a pressure reference source (16). The injection pressure sensor (10) also includes a sensor body (20) and a plunger element (26). If the injection pressure sensor (10) experiences high fluid pressures, the sensor element (14) can fail and fluid can escape past the sensor element (14). When the sensor element (14) fails, the plunger element (26) moves from an inactive position (28) into an active position (32). When the plunger element (26) is in the active position (32), fluid is generally prevented from escaping the sensor body (20).

Abstract: An injection pressure sensor (10) intended for use with a fluid source (12). The injection pressure sensor (10) has a sensor element (14). and a tube member (18). The tube member (18) creates a fluid pathway (20) between the fluid source (12) and the sensor element (14). The tube member (18) contains a collapsible portion (22), such that when the tube member (18) is bent, the fluid pathway (20) is generally closed.

Abstract: An articulated exhaust gas recirculation supply tube for an automotive engine includes an inlet tube with a first end adapted for connection with a source of exhaust gas from an engine and a second end having telescoping joint portion. An outlet tube has a first end adapted for connection with an exhaust gas recirculation control and a second end having a telescoping joint portion. An articulated gas conducting joint is slidingly engaged with the telescoping joint portions of the inlet tube and the outlet tube. A gas sealing member extends about both the telescoping joint portions of the inlet and outlet tubes and the articulated gas conducting joint.

Abstract: An evaporative emission control system is disclosed having a bed of activated carbon effective to adsorb or collect fuel vapors from both the fuel tank and/or an automotive carburetor; the vapors are desorbed or purged back into the engine upon subsequent and specific degree of engine operation. The bed is provided with one or more baffles to route the vapors through the full extent of the activated carbon for improving efficiency of emission control.
