摘要： A dosing valve assembly (200) is disclosed for administering a reducing agent into an exhaust stream within an exhaust manifold of an internal combustion engine. The dosing valve assembly (200) comprises a control valve (108) coupled to a source (110) of the reducing agent, a reducing agent delivery valve (106) constructed and arranged for coupling to the exhaust manifold to enable a specified quantity of reducing agent to be administered into the exhaust stream, and an elongated conduit (214) disposed between the control valve (108) and reducing agent delivery valve (106) for fluidly communicating reducing agent from the control valve (108) to the reducing agent delivery valve (106) . The disclosed arrangement enables the reducing agent delivery valve (106) to be coupled to the exhaust manifold and the control valve (108) to be displaced from the reducing agent delivery valve (106) and away from the high temperature environment associated with the exhaust manifold.

摘要： A compact fuel pressure regulator (10) includes a housing (12) with an interior (13) communicating and inlet opening (16) and an outlet opening (20). The housing defines a valve seat surface (26) in the interior. A cover (22) is provided at an end of the housing and is disposed in the interior. The cover includes a through-hole (24) therein that communicates the outlet opening with the interior. A valve structure (28) is movable within the interior to control fuel flow between the inlet opening and outlet opening. A spring (30) is engaged between the valve structure and the cover so that when pressure of fuel at the inlet opening is greater than a force of the spring, the fuel pushes the valve structure against the bias of the spring and away from the valve seat surface so that fuel flows around a periphery of the valve structure to the outlet opening.

摘要： A reductant delivery unit (10) includes a fluid injector (12) and a flange (20) coupled with the fluid injector. An exhaust boss (28) has a surface (39) defining a through- hole (40) that communicates with a vehicle's exhaust flow path. The flange is coupled to a mounting surface such that the outlet of the fluid injector communicates with the exhaust flow path so as to control injection of urea solution into the exhaust gas flow path. A gasket (32) is sandwiched between the flange and the mounting surface. The gasket has a surface (37) defining a through-hole (38) therein that communicates with the through-hole in the exhaust boss to permit the urea solution to pass from the fluid outlet to the exhaust flow path. Gasket shielding structure (44) covers the surface defining the through-hole in the gasket to prevent the urea solution from contacting the gasket.
