Abstract: A fuel injection nozzle has a tubular body adapted to receive fuel from a fuel line. A restriction member received at the inlet end of the tubular member limits the flow of fuel into the nozzle and is adjustable between minimum and maximum flow rates. The restriction member has an upstream member with a maximum flow orifice through which fuel entering the nozzle passes. A downstream restriction member nests within the upstream member such that a wall of the downstream member is in circumjacent, sliding relationship to a corresponding wall in the upstream member. The downstream member has a minimum flow orifice for establishing the minimum fuel flow into the nozzle and orifices in the wall portion which are blocked by the wall portion of the upstream member in the minimum flow position of the members and are subject to progressive unblocking to thereby establish a flow rate through the nozzle above the minimum.

Abstract: A tip shut-off fluid injector F has its injection device 1 inset to a fixed female interlocking terminal 2 when in the firing position with which a change-over valve 4 is connected by pipes P or is made integral. The terminal 2 includes valves 8 and 9 and, optionally, a by-pass valve 10. A gearbox 12 connects between the valves 8, 9 and 10 and a handwheel 11.

Abstract: A fuel injection nozzle of the present invention has an accumulating chamber in a body in which high pressure fuel fed from the fuel injection pump is stored using a non-return valve. A needle valve is arranged in the body to inject the fuel in the accumulating chamber. A nozzle needle of the needle valve and a valve member are arranged coaxially and in series with each other. Those end portions of the nozzle needle and valve member which are adjacent to each other are slidably and liquid-sealingly fitted together to define a damping chamber between the valve member and the nozzle needle. Further, a damping plunger is coaxially fitted into the valve member. A passage which connects the damping chamber with the side of the fuel injection pump is coaxially formed in the damping plunger and has a reduced area.

Abstract: The present invention contemplates a fluid delivery system for use with one or more individual water blast guns, each of which have an auxiliary shut-off valve integral with the gun and also include electric circuit completion means for operating a pneumatic secondary shut-off valve in series with the high pressure fluid supply conduit feeding each gun. This series arrangement of first and second shut-off valves in the fluid conduit between the pump discharge and each individual gun assures a fail-safe shut-off system which gives the operator of each gun the assurance that upon release of the water blast gun trigger that cessation of the water blast from the gun nozzle will occur. Accordingly, the likelihood of the operator falling over backwards upon release of the gun trigger is eliminated and risk of a dropped runaway water blast gun that failed to shut-off is eliminated.

It further includes a plunger, which is compressed by water pressure in an upper chamber, so as to move it down to the closed position, and a manually operated release mechanism will tilt a valve, which will release the water pressure in the upper chamber, and cause it to flow out of the sprayer plate of the device.

Abstract: The disclosed system controls, through novel pressure and valving adjustment mechanisms, the application of dampening fluid to the ink roll or offset plate on the plate cylinder of an offset printing press. The dampening fluid passes through a pressure compensator which adjusts the fluid pressure in response to changes in the speed of the press. The fluid at the adjusted pressure is then directed to a spray bar, where it is discharged through a plurality of nozzles. The fluid is directed to the spray bar by a multiple valve, page control assembly. In the page control assembly fluid from a common manifold is discharged through a plurality of dual control valves to respective nozzles. Closure elements for the respective valves are operated by air pistons. A plurality of needle elements for the respective valves are axially adjusted by a common manual control so that adjusting the manual control adjusts the amount of fluid from one segment of the spray bar, preferably corresponding to a full page.

Abstract: A fuel injection nozzle proper comprises a spring-loaded valve which is opened by fuel pressure in a fuel supply passageway to inject fuel directly into an engine cylinder when the fuel pressure is above a first predetermined value. A check valve is provided in the fuel supply passageway which is opened when the fuel pressure is above a second predetermined value which is higher than the first predetermined value to allow fuel flow through the check valve. A longitudinal passageway having an orifice formed through the check valve element allows fuel flow therethrough even when the fuel pressure is below the second predetermined value so that fuel flows through the check valve to a lesser extent when the check valve is closed than when the check valve is opened so that the fuel flow is constricted and fuel injection is prolonged at low engine speeds thereby reducing combustion noise.

Abstract: Filamentary material to be dyed is moved under tension at high speed past a dye-spraying nozzle adapted to spray such material intermittently. The dye application may be varied by applying the dye as the filamentary material moves past a series of nozzles controlled to spray dye in different phase relationships. The dye application to the filamentary material may also be processed by applying a twist to the sprayed filamentary material by applying a gaseous blast tangentially thereto. The dye may be applied in spaced chambers having baffles which engage the dye jets whereby dye is reflected into the moving filamentary material.

Abstract: A fuel injection valve for an internal combustion engine has a main fuel valve formed by a needle urged against a valve seat by a spring and also includes a solenoid to pull the valve needle away from the seat for fuel metering purposes. In addition, the valve has an extension in which a pestle with two enlarged ends is axially carried in two spring support cups. The enlarged ends of the pestle also act as valves in such a manner that even low fuel-flow causes a fluttering of the pestle, resulting in good fuel atomization.
