Linear solenoid for EGR valve

A linear solenoid for an EGR valve having a tube casing comprising:

• a fixed magnetic nucleus (1), an electrical bobbin (2), a sliding bushing (3), a tube carcass (4), a mobile magnetic nucleus (5), an axle or connecting rod (6), a conical magnetic nucleus (7) and a setting flange (8), the fixed magnetic nucleus (1) having a tubular body (9) with a superior circular border (10) having a central puncture (11) and two orifices (12) next to a peripheral border (18), the mobile magnetic nucleus (5) having a cylindrical body with a central puncture (13) which does not pass through a superior extremity thereof, and a central puncture (14) which does not pass through an inferior extremity thereof, the conical magnetic nucleus (7), having a cylindrical body with a superior conical terminal (15) and a superficial socket (16) leading to a central puncture (17) which extends to the inferior extremity, where there is provided externally, one peripheral border (18), with a circular base having a minor diameter (19).

A linear solenoid for an EGR valve, the valve having a carcass with a deep print, the linear solenoid comprising:

• a fixed magnetic nucleus (20), a sliding bushing (21), an electrical bobbin (22), a magnetic closing (23), a mobile magnetic nucleus (24), an axle or connecting rod (25), a conical magnetic nucleus (26), the carcass with the deep print (27) and a fixing flange (28), the fixed magnetic nucleus (20) having a tubular body (29) with a circular superior border (30) having a central puncture (31) and two orifices (32) next to the peripheral border, the mobile magnetic nucleus (24) having a cylindrical body provided with a central puncture (33) which does not pass into a superior extremity and a central puncture (34) which does not pass into an inferior extremity, a conical magnetic nucleus (26) having a cylindrical body with a superior conical terminal (35) and a superficial socket (36) leading to a central puncture (37) which extends to the inferior extremity, having, externally, one peripheral border (38) with a circular base of a minor diameter (39), the carcass with the deep print having in a superior part and close to a mouth thereof, a slim peripheral strangulation (40).

A linear solenoid for an EGR valve, having a conformed cold carcass, the solenoid comprising:

• a fixed magnetic nucleus (41), a sliding tube (42), an electrical bobbin (43), a mobile magnetic nucleus (44), a washer (45), a carcass (46) an integrated conical magnetic nucleus (47) and a setting flange (48);
• the fixed magnetic nucleus (41) having a tubular body (49) with a circular superior border (50) provided with a central puncture (51) and two orifices (52) next to the peripheral border, the mobile magnetic nucleus (44) having a cylindrical body with a central puncture (53) which does not pass into a superior extremity, the conical magnetic nucleus (47) incorporated centrally in a base of the conformed cold carcass (46), assembled with only one part, having a cylindrical body with a conical superior terminal (54) and one superficial socket (55) which leads to a central puncture (56) extending to the inferior extremity, whore a base (57) is exposed in the inferior part of the carcass.
