    摘要: Exhaust gas recirculation (EGR) valve actuator device (4) in an internal combustion engine, comprising an actuator body (8) housing
    - the stem (12) of an exhaust gas recirculation valve (16), extending along an axial direction (X-X),
    - motor means (32) of said exhaust gas recirculation valve (16) configured so as to move the recirculation valve (16) along said axial direction (X-X), to pass from an open configuration to a closed configuration,
    - transmission means (36), interposed between the motor means (32) and the exhaust gas recirculation valve (16),
    - support and guide means (40) of the exhaust gas recirculation valve (16)
    - heat reducing and sealing means (76), in correspondence of a connection interface (80) of the actuator body (8) with an associable valve body (84), which houses an exhaust gas passage duct (88), wherein the actuator body (8) is mechanically separable/connectable from/to said associable valve body (84).

    摘要: Exhaust gas recirculating valves for internal combustion engines are known, said valves comprise a housing (2) with an exhaust gas inlet (4) and an exhaust gas outlet (6), a valve closing body (10), a valve rod (12) on which the valve closing body (10) is fixed and which can be moved by an actuator, a valve seat (8) between the exhaust gas inlet (4) and the exhaust gas outlet (6), wherein the valve closing body (10) can be lowered onto said valve seat by moving the valve rod (12) and the valve closing body (10) can be raised from said valve seat by an opposing movement, a guide bushing (14) via which the valve rod (12) is guided in the housing (2), and a sealing ring (18) which lies on the guide bushing (12) end opposite the valve closing body (10). However, jamming or loss of sealing tightness of the valve are frequent problems. The invention therefore proposes forming a peripheral gap (32) between the valve rod (12) and the guide bushing (14) in a first section (30) of the guide bushing (14), said section pointing towards the sealing ring (18). The mechanical load of the sealing ring (18) is thereby reduced and the guiding sections are shortened.

    摘要: The invention relates to a valve (100) including a first duct (1) and a second duct (2) which extends perpendicularly to the first duct. According to the invention, the first duct opens into a connecting segment (3) at which it is connected to the second conduit, such as to define an intersection forming the seat (7) of a flap (8) that can slide in the connecting segment in a direction that is perpendicular to the seat between a closed position and an open position. The aforementioned connecting segment includes two opposing flat walls (4, 5) which are connected by a base wall (6). The first duct opens onto one of the flat walls (4) and the base wall partially surrounds the flap in parallel with the direction of flow at a distance from the edge (15) of the flap, such that, in the open position, the base wall, the edge of the flap and the seat define a passage (18) having a cross-section that increases from the centre line (19) of the base wall in the direction of the areas (17) at which the base wall is connected to the second duct.
