摘要： A fuel injector is provided which has an improved structure capable of adjusting fuel jet characteristics such as the quantity of fuel to be injected to an engine and a fuel injection time lag after the fuel injector is assembled. The fuel injector includes an air gap (H) adjusting screw (31) and a spring (38) pressure adjusting screw (37). The air gap adjusting screw (31) serves to change an air gap (H) between a stator (34) and an armature (32) of a solenoid valve to adjust the quantity of fuel to a target one. The spring pressure adjusting screw serves to change a spring pressure urging a valve in a spray hole-closing direction to regulate a spray hole open duration, thereby adjusting the fuel injection time lag or the quantity of fuel.

摘要： The metering valve (24) is fitted in a hollow body (12) of the injector (11) and is controlled by the armature (27) of an electromagnet (26). The travel of the armature (27) towards the electromagnet (26) is arrested by a stop element (71) fittable to the hollow body (12) by means of a threaded element (68), which is screwed to a thread (18) of the hollow body (12) with a calibrated tightening torque to adjust the travel of the armature (27) towards the electromagnet (26) by means of the tightening torque. The method of adjustment includes the steps of fitting the stop element (71) in the hollow body (12) by means of a threaded element (68), and applying a calibrated tightening torque to the threaded element (68).

摘要： The design and construction of past injector assemblies having an injector sleeve manufactured from a deformable material used the deforming characteristics of the injector sleeve to form a combustion seal separating a combustion chamber from a cooling liquid jacket. Additionally, the injector sleeve was generally used in conjunction with a resilient means to form the coolant seal between the cooling liquid jacket and a fuel injector. Deforming the injector sleeve to produce the combustion seal made it difficult to remove during inspections and maintenance schedules and virtually impossible to reuse. The present invention overcomes these problems by providing an injector sleeve (54) manufactured from a relatively non-deformable material which is used in conjunction with a plurality of seal rings (76) to establish only a coolant seal between the cooling liquid jacket (28) and a fuel injector (112). An injector cone (84) has a tapered lower portion (86) which is seated in a frusto-conical portion (50) disposed within a cylinder head (18) to establish an independent combustion seal.

摘要： The injector (10) for intermittently injecting fuel under high pressure in an internal combustion engine is provided with an injector valve member (18). The movement of this injector valve member (18) to open and close a fuel discharge orifice (24) is controlled by the fuel pressure in a control chamber (40) acting on a valve piston (26) on the side opposite to the discharge orifice (24). A cylindrical member (36) surrounds the upper part (30) of the valve piston (26). Energization of a solenoid (44) results in the opening of a pilot valve (46) and a subsequent quick drop of the fuel pressure in the control chamber (40). The solenoid (44) in addition to its function as a high speed actuator for the pilot valve (46) is also used to carry and transmit the force resulting from the fuel pressure in the control chamber (40) and acting on the cylindrical member (36), on the solenoid (44) and on further members (48, 50, 52, 14). Since the solenoid (44) can therefore be mounted directly within the injector housing (14), the design of the injector (10) can be very compact and simple.

摘要： A control valve (19) for an injector (10) comprising a valve body (38) having of a control chamber connected to a drain conduit via a hole (49) terminating at a flat surface (68) of the valve body (38). The plunger of the valve (19) consists of a plate (67) housed in a seat (66), the bottom wall (86) of which arrests the travel ("b") of the plate (67). This is controlled by the anchor (28) of an electromagnet (20), which anchor (28) presents a rod (31) arrested directly by an adjustable stop (78) after traveling a distance "a" greater than travel "b". The opening and closing time of the valve (19) is therefore unaffected by wear on the stop (78) of the anchor (28). The rod (31) of the anchor (28) is in one piece with a stem (37) activating the plate (67), and with a threaded portion (77) screwed to the anchor (28).
