Marchetti, Springfield, Mass., assignors to American Bosch Arma Corporation, a corporation of New York Application September 26, 1955, Serial No. 536,542 7 Claims. (Cl. 299107.6)
This invention relates to fuel injection nozzles and has particular reference to a new and improved nozzle body and nozzle assembly which is simple and more economical in construction and yet efiicient in operation.
An object of the invention is to provide a new and improved device of the type set forth wherein the nozzle and nozzle body are assembled as a complete unit by providing a simple and more economical construction which can be installed and serviced as a complete unit.
Another object is to provide a device of the type set forth wherein the nozzle and holder are joined together as a unit and wherein a new and improved securing arrangement is provided. 7
Other objects and advantages of the invention will be apparent from the following description taken in connection with the accompanying drawings. It will be understood that changes may be made in the details of construction and arrangement of parts shown and described as the preferred form has been given by way of illustration only.
' Referring to the drawings:
Fig. 1 is a longitudinal sectional view of a device embodying the invention;
Fig. 2 is a view generally similar to Fig. 1 but showing another form of the invention;
Fig. 3 is a sectional view taken on line 33 of Fig. 2, looking in the direction of the arrows;
Fig. 3A is a sectional view taken on line 3A--3A of Fig. 2 looking in the direction of the arrows.
Fig. 4 is a view generally similar to Figs. 1 and 2 but showinganother form of the invention;
Fig. 5 is a sectional view taken on line 55 of Fig. 4, looking in the direction of the arrows; and
Fig. 6 is a view generally similar to Figs. 1, 2 and 4 but showing a slightly different form of the invention.
'Referring more particularly to the drawings wherein similar reference characters designate corresponding parts throughout, the form of the invention shown comprises the nozzle body 10 having the fuel passage or duct 11 and the coupling 12 for connection to the fuel line.
,The nozzle portion 13 is adapted to be secured in aligned relation with the body 10 and is provided with the spring chamber 14 and the discharge passage or duct 15 leading outwardly therefrom'for the discharge of fuel into the combustion chamber.
The passage of fuel through the discharge passage 15 is controlled by the nozzle valve 16 having the extension 17 extending into the spring chamber 14 and operatively connected to valve retainer 18 which is mounted for sliding movement in slideway 19 and the extent of sliding movement or adjustment of retainer 18 is limited by internal peripheral shoulder 20.
Valve retainer 18 also serves as a spring seat for one end of spring 21 and the opposite end of said spring engages the end face 22 of spring chamber 14 surrounding discharge passage 15 whereby spring 21 will control ICC the opening pressure of the nozzle valve 16 which is opened by fuel pressure.
The adjacent end faces 23 and 24 of body portion 10 and nozzle portion 13 respectively are relatively flat ground surfaces adapted to provide the leak proof connection between the portions.
The body portion 10 is provided with the peripheral groove 25 adjacent to but spaced from said end faces 23 and the nozzle portion 13 is provided with the peripheral groove 26 adjacent to but spaced from the end face 24 and the clip 27 is provided with its ends 28 and 29 in grooves 25 and 26 respectively to retain the body portion 10 and nozzle portion 13 aligned assembly.
The clip 27 may be formed from a link shaped piece of material having its ends 28 and 29 rolled into the 1 grooves 25 and 26 whereby a tight leak proof connection is formed between the parts.
The construction shown in Fig. 2 is generally similar to that of Fig. 1 but a slightly modified form of the body portion 10 and nozzle portion 13 is provided. In this construction the adjacent end of body portion 10 is provided with the projection 30 which is preferably annular, and which extends into portion 19 in the adjacent end of nozzle portion 13 by a pressed fit and the engaging faces 23 and 24 are preferably ground surfaces, as previously described, for forming a leak proof connection.
If desired, the projection 30 may be provided with the peripheral grooves 31 having resiliency.
In Figs. 4 and 5 the arrangement shown is generally similar to that of Figs. 1 and 2 but the valve connection between the body portions 10 and 13 is the reverse of that shown in Fig. 2, namely, the integral extension 30 is provided on the nozzle portion 13 instead of on the body portion 10 and the peripheral grooves 31 for resiliency are also provided on the nozzle portion rather than on the body portion. Also, the slidable valve retainer 18 is eliminated and the spring 21 is a conical spring with its cross section decreasing progressively away from discharge passage 15 and the spring is covered by the spring cap 32 having the openings 33 therethrough and the end of valve extension 17 passes through spring 21 and the end of cap 32 and is provided with the enlarged end 34. The washer 35 may be provided between p the end of cap 32 and enlarged end 34.
In the construction shown in Fig. 6, the valve retainer 18 is positioned within the bore 19a which is formed in the end of the body portion 10 and the diameter of spring chamber 14 is smaller than the diameter of chamber 19a I whereby the shoulder or stop 20 is formed by the differthat shown in Fig. 2 except that the projection end 30 of the body portion contains the retainer chamber 19a, as previously described.
It is pointed out that except for the form of the invention shown in Fig. 1, that each of the forms shown can employ the fastening or securing clip 27, or not, as de' sired, but that with such clip or joining means employed, when the device is removed from the engine, it insures that both the body portion and the nozzle portion will be removed as a unit in those cases where the nozzle portion might stick for any reason in the engine head.
From the foregoing it will be seen that new and improved means have been provided for obtaining all of the objects and advantages of the invention.
