A direct acting hydraulic valve lifter of the type that is reciprocably journaled as in the cylinder head of an internal combustion engine so as to be engaged by a cam on an engine driven camshaft to control opening and closing movement of an associate valve. The lifter includes a follower body having a circular outer tubular wall with an inner integral web closely adjacent to one end thereof that terminates at a stepped bored integral depending piston, the one end thereof being closed by a disk cam engaging foot which forms with the piston and a surface of the web a fluid reservoir. A baffle, fixed to the plunger and to inner surface of the tubular wall, defines an oil supply passage which is adapted to receive fluid via a side port in the tubular wall and to be in flow communication with the fluid reservoir via an aperture in the web. A cup-shaped, closed end cylinder member slidably encircles the plunger to form therewith a hydraulic lash adjuster having a pressure chamber therein. In one enbodiment, a mechanical retainer is operatively secured to the tubular wall whereby to retain the cylinder member in unit assembly on the plunger. In a preferred embodiment, lubricating oil in the pressure chamber and in a leak-down flow path between the cylinder member and plunger and a one-way ball valve controlling flow into the pressure chamber are operative to hold the cylinder member in unit assembly on the plunger.

A diesel unit fuel injector includes a pump assembly having an externally actuated plunger reciprocable in a bushing which with the plunger defines a pump chamber, with flow therefrom during an injection cycle portion of the pump stroke being directed to a fuel injection nozzle of the assembly. The injection nozzle includes a needle type differential area injection valve that is normally biased to a valve closed position by a valve return spring which is positioned in a spring chamber and which is operatively connected to the opposite end of the injection valve. Passage means, including orifice passage are used to direct spill flow from the pump chamber at the end of an injection cycle to the spring chamber to effect closure of the injection valve at a valve closing pressure which is greater than the valve opening pressure so that the pressure of the discharge of fuel at the end of an injection cycle is relatively great whereby to effect increased penetration of the discharged fuel into the associate combustion chamber of a diesel engine.

Diesel unit fuel injector with spill assist injection needle valve

An electromagnetic unit fuel injector for use in a diesel engine includes a housing with a pump therein defined by an externally actuated plunger reciprocable in a bushing and defining therewith a pump chamber for the discharge of fuel to a spring biased, pressure actuated fuel injection nozzle. The pump chamber is also connected to a fuel chamber via a solenoid actuated, normally open, pressure balanced control valve controlled passage to permit the ingress and egress of fuel. The solenoid and control valve are located concentrically with respect to the plunger. During a pump stroke, the solenoid can be energized to move the valve in position to block flow from the pump chamber to the fuel chamber so as to allow the pressurization of fuel by the pump to effect discharge of fuel from the injection nozzle.

Electromagnetic unit fuel injector

An electromagnetic fuel injector has an axially extending guide pin fixed to an armature and slidably received in the solenoid pole piece to axially guide the armature during its movement thereof relative to the solenoid pole piece. The guide pin has a sleeve supported thereon for engagement at one end with a surface of the armature and extending at its opposite end axially outboard the armature for abutment against the solenoid pole piece whereby to serve as an abutment stop so as to establish a predetermined minimum working air gap between the opposed working surfaces of the armature and an associated solenoid pole piece. An armature return spring has one end thereof in abutment with a free end of the guide pin to bias the armature in an axial direction away from the solenoid pole piece and has its opposite end in abutment against an externally accessible abutment screw whereby the force of the armature return spring can be adjusted as desired. In a preferred embodiment, an additional spring is operatively positioned to assist the armature return spring.

Electromagnetic fuel injector with adjustable armature spring

A fuel injection pump assembly in which fuel delivered from individual cam lobe driven pump plungers is controlled by an engine driven drive shaft rotated control valve, the position of which, relative to the spill ports from the plungers, is controlled by means of a hydraulic governor. A separate governor cam lobe is used to also actuate the plungers whereby fluid supplied to the hydraulic governor is at a flow rate proportional to pump speed and therefore, engine speed.

Fuel injection pump

A separate valve, rotatable with a pump control valve in a multiple plunger type fuel injection pump used to sequentially supply fuel to a number of fuel injection nozzles, is actuated by a solenoid to control fuel spill from each plunger whereby to control quantity and timing of injection.

Solenoid valve controlled fuel injection pump

A fuel injector nozzle includes a housing having a compartment therein divided by a valve seat disc into a control chamber of predetermined volume on one side of the valve seat disc and a fuel chamber on the other side thereof, the valve seat disc having an aperture therethrough to effect communication between the control chamber and the fuel chamber, the housing having an inlet to the fuel chamber and an outlet from the fuel chamber for injection of fuel into an engine cylinder, a check valve in the form of a sleeve movably positioned in the fuel chamber for controlling flow from the control chamber through the aperture in the valve seat disc to the fuel chamber, and an inwardly opening, spring biased injection valve positioned in the fuel chamber with its enlarged diameter stem end guided in the check valve sleeve and having its other end positioned to control fuel injection out through the outlet. Fuel pressure built-up in the control chamber due to leakage of fuel from the fuel chamber past the mating sliding surfaces of the injection valve and check valve forces the check valve to an open position whereby to release pressure from the control chamber between injection strokes of the injection valve whereby a regulated pressure is maintained in the control chamber to act on the enlarged diameter end of the injection valve.

Fuel injector nozzle

An inwardly opening valve type, fuel injection nozzle is provided with a part or parts thereof electrically insulated relative to its housing and the movable injector valve therein so that when the injector valve is closed an electrical circuit can be completed through the injector valve and housing and when the injector valve is moved to an open position, the continuity of this circuit is broken, By connecting an electrical continuity tester to this circuit, the opening and closing of the injector valve can be detected and can be used to set the timing of a diesel engine.

Injection timing nozzle

A fuel injection nozzle assembly includes a nozzle body and a compressible valve therein having a valve head that is normally in loaded abutment against a valve seat in the nozzle body to block the discharge of fuel therefrom, the compressible valve further including a stem extending from the valve head which is fixed at its opposite end to the valve body, the stem including a thin wall, tubular compressible stem portion next adjacent to the valve head and connected thereto by an annular shoulder, the compressible stem portion having an outside diameter substantially greater than the diameter of the valve head with the thin wall of the compressible stem portion being sized so that when fuel, in an annular fuel chamber in the nozzle body encircling the compressible stem portion, at a high fuel pressure acts on the annular shoulder, it will cause a reduction in the normal longitudinal extent of the compressible valve to effect unseating of the valve head from the valve seat and, when the fuel in the fuel chamber is at a reduced pressure, the valve head is seated against the valve seat.
