摘要： A two stage lift injection nozzle includes a nozzle holder (10) to which is secured a nozzle body (15) which accommodates a fuel pressure actuated valve member (18). The valve member is biased into engagement with a seating (23) by a first spring (27) and after a predetermined movement of the valve member away from the seating it engages a spring abutment (34) of a second spring (32). The movement of the valve member away from the seating against the action of both springs is limited by the engagement of the abutment (34) with stop surfaces (39) defined by recesses (36) in the wall of a chamber (12) in the holder and in which the springs are located.

摘要： A fuel injector for supplying fuel to an engine has an elongated body 10 in which is defined a bore 12 at one end of which is formed a seating 13. Located with clearance within the bore is a fuel pressure actuated elongated valve member 15 which at one end is shaped for co-operation with the seating. At its other end the valve member is guided for movement by a guide bush 29 which is able to move radially to a limited extent in the body. Between the guide bush and the seating the valve member has an enlargement 17 which co-operates with the wall of the bore to ensure that the valve member remains concentric with the seating as it moves away from the seating. The guide bush is conveniently formed by an outer bush 30 and an inner bush 31 with the inner bush able to move axially relative to the outer bush. The fuel pressure at the inlet of the injector acts on the inner bush to assist the initial movement of the valve member away from the seating.

摘要： A connector is disclosed which is intended for use with an injector. The connector comprises a projection (17) defining an inlet passage (19) sealed, in use, within a bore (15) provided in the injector. The inlet passage (19) communicates with at least one outlet passage (21). The connector further comprises at least one tooth (23) received within a recess (13A, 24) provided in the injector to secure the connector to the injector. The recess (13A, 24) is conveniently defined by a body (10) and nut (13) forming part of the injector.

摘要： A two stage lift fuel injection nozzle includes a nozzle holder (10) in which is defined a chamber (16) housing a pair of springs (15, 24) disposed in axial relationship. The springs provide a two stage biasing force for a valve member (13) slidable in a nozzle body (11) which is secured to one end of the holder. The spring (24) which is adjacent the nozzle body engages a reaction member (26) in the form of an annular component (30) defining legs (31) which can be expanded outwardly into gripping engagement with the wall of the chamber by means of a plug (32) which is in screw thread engagement with the component.

摘要： A fuel injection nozzle has a body 11 in which is formed a bore 15 at one end of which is a seating 18. Outlet orifices 19 extend from the bore and located in the bore is a valve member 17 shaped at one end to engage the seating and spring biased into engagement with the seating to prevent fuel flow through the orifices. The initial movement of the valve member away from the seating is limited and during this limited movement the fuel flow through the orifices is limited by an annular clearance defined by axially extending cylindrical surfaces 37, 38 formed by the wall of the bore and the valve member.
