- Disc 32 is a permanent magnet armature of a coil 40 threaded onto a centre post 42 in body 12.
- coil 40 When coil 40 is energized with a positive current as shown in Figure 2, coil 40 attracts disc armature 32 against the bias of spring 30, the fuel pressure in inlet 14 lifts ball-valve 18 and push-rod 34, and fuel flows around ball 18 and is metered through orifice 20 to central passage 22.
- coil 40 When the desired amount of fuel has been metered into passage 22, coil 40 is de-energized, and spring 30 re-engages fuel-metering valve 18 with its seat 28.

- Injector 10 is assembled by placing ball-valve 18 and push-rod 34 in body 12, placing armature 32 and spring 30 in body 12, and threading coil 40 on post 42. Coil 40 is screwed on post 42 until it makes contact with armature 32, i.e., until it is bottomed out against armature 32. Coil 40 is then unthreaded, i.e., backed out the proper amount to set a desired air gap between armature 32 and coil 40.

- Figure 6 is a view of the Figure 4 injector showing the position of the parts during delivery of a fuel-air charge.
- Referring first to Figures 1-3, an
injector 10 has abody 12 that receives fuel through aninlet 14 and air through aninlet 16. A ball-typefuel metering valve 18controls inlet 14; whenball valve 18 is opened, fuel is metered through anorifice 20 to acentral passage 22 and a poppet-type charge-delivery valve 24 which engages avalve seat 26 surrounding the lower end ofpassage 22; when opened,valve 24 delivers a charge of fuel and air directly into an engine combustion chamber. - Ball-
valve 18 is biased against aseat 28 ininlet 14 by acoil spring 30 acting through adisc 32 and a push-rod 34.Poppet valve 24 is biased againstseat 26 by a diaphragm-type spring 36 acting on astem 38 ofpoppet valve 24. -
Disc 32 is a permanent magnet armature of acoil 40 threaded onto acentre post 42 inbody 12. Whencoil 40 is energized with a positive current as shown in Figure 2,coil 40 attractsdisc armature 32 against the bias ofspring 30, the fuel pressure ininlet 14 lifts ball-valve 18 and push-rod 34, and fuel flows aroundball 18 and is metered throughorifice 20 tocentral passage 22. When the desired amount of fuel has been metered intopassage 22,coil 40 is de-energized, andspring 30 re-engages fuel-metering valve 18 with itsseat 28. - Another
permanent magnet armature 44 is secured onvalve stem 38.Armature 44 hasapertures 45 that allow air to flow frominlet 16 topassage 22. Whencoil 40 is energized with a negative current as shown in Figure 3,coil 40 attractsarmature 44 against the bias ofspring 36,poppet valve 24 is displaced fromseat 26, and the fuel-air charge inpassage 22 is delivered into the engine. When the charge has been delivered into the engine,coil 40 is de-energized, andspring 36 re-engages charge-delivery valve 24 with itsseat 26. - When
coil 40 is energized with a positive current to attractarmature 32 and meter fuel intopassage 22,armature 44 is repelled and adds to the valve-closing force ofspring 36 to maintain charge-delivery valve 24 engaged withseat 26. Whencoil 40 is energized with a negative current to attractarmature 44 and deliver the fuel-air charge frompassage 22,armature 32 is repelled and adds to the valve-closing force ofspring 30 to maintain fuel-metering valve 18 engaged withseat 28. - When
armature 32 is in the position shown in Figures 1 and 3, it engagesstops 46 which maintain it in proper alignment inbody 12. -
Injector 10 is assembled by placing ball-valve 18 and push-rod 34 inbody 12, placingarmature 32 andspring 30 inbody 12, andthreading coil 40 onpost 42.Coil 40 is screwed onpost 42 until it makes contact witharmature 32, i.e., until it is bottomed out againstarmature 32.Coil 40 is then unthreaded, i.e., backed out the proper amount to set a desired air gap betweenarmature 32 andcoil 40. A lock-nut 48 is threaded ontopost 42 to holdcoil 40 in the desired position. Anadjustment ring 50 is threaded intobody 12 and positioned to set the desired force ofspring 30; O-rings seal ring 50 tobody 12 andcoil 40, and a set-screw 56 holdsring 50 in the desired position.Poppet valve 24 is inserted intobody 12, andarmature 44 is threaded ontovalve stem 38.Armature 44 is screwed onvalve stem 38 until it is bottomed out againstcoil 40, then it is backed out the proper amount to set a desired air gap betweenarmature 44 andcoil 40. A lock-nut 58 is threaded ontostem 38 to holdarmature 44 in the desired position. Aclamp ring 60 is inserted intobody 12, andspring 36 is fitted intobody 12 and overstem 38. Anadjustment nut 62 is threaded ontostem 38 and is positioned to set the desired force ofspring 36; a lock-nut 64 is threaded ontostem 38 to holdadjustment nut 62 in the desired position. Acap 66 is threaded intobody 12 to securespring 36 and close the top ofbody 12; an O-ring 68seals cap 66 tobody 12. - Referring next to Figures 4-6, an
injector 110 has amulti-piece housing 112 that receives fuel through a fuel-supply tube 114 and air through an air-supply tube 116. A ball-type fuel-metering valve 118 controls fuel flow fromtube 114; when ball-valve 118 is opened, fuel is metered through anorifice 120 to acavity 122. A poppet-type charge-delivery valve 124 engages avalve seat 126 in anozzle 127 opening from the lower end ofcavity 122; when opened,valve 124 delivers a charge of fuel and air directly into the engine. - Ball-
valve 118 is biased against aseat 128 by acoil spring 130 acting through adisc 132, a push-rod 133 threaded intodisc 132, and apin 134.Poppet valve 124 is biased againstseat 126 by acoil spring 136 acting through adisc 137 threaded onto thestem 138 ofpoppet valve 124. -
Discs coil 140 wound on amagnetic core 142. Whencoil 140 is de-energized as shown in Figure 4,armature 132 is attracted toward the top ofcore 142,engaging ball valve 118 with itsseat 128, whilstarmature 137 is attracted toward the bottom ofcore 142, engagingpoppet valve 124 with itsseat 126. - When
coil 140 is energized with a positive current as shown in Figure 5, coil 140repels armature 132 against the combined bias ofspring 130 and the magnetic attraction betweenarmature 132 andcore 142, the fuel pressure ininlet 114 lifts ball-valve 118 andpin 134, and fuel flows aroundball 118 and is metered throughorifice 120 tocavity 122. When the desired amount of fuel has been metered intocavity 122,coil 140 is de-energized, and the combined bias ofspring 130 and the magnetic attraction betweenarmature 132 andcore 142 re-engages fuel-metering valve 118 with itsseat 128. - When
coil 140 is energized with a negative current as shown in Figure 6,coil 140repels armature 137 against the combined bias ofspring 136 and the magnetic attraction betweenarmature 137 andcore 142,poppet valve 124 is displaced fromseat 126, and the fuel-air charge incavity 122 is delivered into the engine. When the charge has been delivered into the engine,coil 140 is de-energized, and the bias ofspring 136 and the magnetic attraction betweenarmature 137 andcore 142 re-engages charge-delivery valve 124 with itsseat 126. - When
coil 140 is energized with a positive current to repelarmature 132 and meter fuel intocavity 122,armature 137 remains attracted tocore 142 and adds to the valve-closing force ofspring 136 to maintain charge-delivery valve 124 engaged withseat 126. Whencoil 140 is energized with a negative current to repelarmature 137 and deliver the fuel-air charge fromcavity 122,armature 132 remains attracted tocore 142 and adds to the valve-closing force ofspring 130 to maintain fuel-metering valve 118 engaged withseat 128. -
