  • Patent number: 9982641
    Abstract: A valve assembly for a fluid injection valve may comprise a valve body, a valve needle moving in a cavity of the valve body, an armature in the cavity for actuating the valve needle, and a particle retainer. The cavity may extend axially through the valve body to connect a fluid inlet end to a fluid outlet end of the valve body and have a valve seat adjacent to the fluid outlet end. The first portion of the cavity may limit movement of the armature in the axial direction towards the fluid outlet end by a bottom surface having a central opening from which a second portion of the cavity extends towards the fluid outlet end. The shaft of the valve needle may extend through the opening into the second portion. The particle retainer element may bear on the bottom surface, circumferentially surrounding the shaft of the valve needle and overlapping the opening.

  • Patent number: 9593656
    Abstract: A fuel injector includes a valve member for selectively preventing and permitting flow of fuel through a valve seat by selectively engaging and disengaging the valve seat, an actuator for selectively applying a force to the valve member in order to unseat the valve member from the valve seat, and a return spring which biases the valve member into contact with the valve seat when the actuator is not applying the force to the valve member. A calibration tube is positioned within the fuel tube and holds the return spring in compression so as to set a force on the return spring to achieve a desired dynamic flow of fuel through the fuel injector. The calibration tube includes at least one protrusion extending outward therefrom such that the protrusion engages the fuel tube, thereby creating a spring fit between the calibration tube and the fuel tube.

    Abstract: A hoop filter is adapted to protect a pressure control orifice plate in a common rail fuel injector from being plugged by contaminated fuel. Shaped in the form of a band, the filter is configured to engage the circumference of a pressure control orifice plate. For purposes of filtration, the orifice plate has a circumferential groove which intersects at least one internal orifice; the groove is externally covered by the body of the hoop filter. In one embodiment, the band-shaped hoop filter has small apertures adapted to filter out any particle having a size greater than 50 microns. In another disclosed embodiment, the hoop filter is a solid band-shaped edge filter without any apertures; instead the orifice plate periphery includes circumferentially spaced vertical grooves which interface with the bottom and top edges of the filter to restrict entry of contaminant particles.

  • Patent number: 8919678
    Abstract: A filter for use with overhead sprinkler irrigation systems is disclosed. The filter includes a body, a removable screen, and a manually-actuated plunger adjacent the screen. A water hammer table is partitioned in the body and located above the plunger. The plunger is positioned for reciprocal movement through a debris outlet between an open, debris-discharging position, and a closed filtering position. The plunger defaults to the closed filtering position by pressurized water flowing through the body. The water is simultaneously filtered through the screen and passes out a clean water outlet while debris accumulates within the body. The plunger may be manually retracted to the open, debris-discharging position at any time, whereby accumulated debris is flushed out of the body through the debris outlet by residual water flowing therethrough.

  • Patent number: 7900854
    Abstract: A filter for use with overhead sprinkler irrigation systems is disclosed. The filter includes a hollow cylindrical body, a removable screen, and a manually-actuated plunger adjacent the screen. The plunger is positioned for reciprocal movement through a debris outlet between an open, debris-discharging position, and a closed filtering position. The plunger defaults to the closed filtering position by pressurized water flowing through the body. The water is simultaneously filtered through the screen and passes out a clean water outlet while debris accumulates within the body. The plunger may be manually retracted to the open, debris-discharging position at any time, whereby accumulated debris is flushed out of the body through the debris outlet by residual water flowing therethrough.

  • Patent number: 7891587
    Abstract: The invention relates to an intermediate plate for a fuel injector, comprising a high-pressure through-hole which connects a high-pressure passage in a valve body and is connected to a high-pressure fuel reservoir, to a high-pressure space in a nozzle body, wherein the intermediate plate is arranged between the valve body and the nozzle body. In order to improve the injection behaviour of a fuel injector provided with the intermediate plate, in particular during multiple injection of small injection quantities, the high-pressure through-hole has a cross-sectional profile which improves the flow through the high-pressure through-hole from the valve body towards the nozzle body and impairs the flow in the opposite direction from the nozzle body towards the valve body.

  • Patent number: 7878427
    Abstract: An injector having an injector body to which a fuel line is connected for delivering fuel at high pressure. A filter bore is formed in the body and a fuel filter is disposed, through which filter the delivered fuel flows. A sealing seat is formed in the filter bore against which seat the end of the fuel line is pressed upon fastening of the fuel line to the injector body. The filter bore discharges at the outside of the injector body. The sealing seat is disposed with its longitudinal axis inclined to the longitudinal axis of the filter bore, and in the injector body, a bore extending at least approximately coaxially to the sealing seat is provided, into which the end region of the fuel line plunges. By the end region, plunging into the bore, of the fuel line, an outer end region of the filter bore, discharging at the outside of the injector body, is separated from an inner end region, subjected to high pressure, of the filter bore, and the fuel filter is disposed in the inner end region of the filter bore.

  • Patent number: 7878426
    Abstract: A sanitary outlet unit (1) is provided, including an outlet armature (2), with a flow regulator (4) in a region of the water outlet (3) thereof, wherein an aeration device is provided for aeration of the water flow. The outlet unit (1) provides that the aeration unit (5) is located in the outlet armature (2) and/or in at least one water line leading to the outlet armature (2) separately from the flow regulator (4). Through the spatial separation of the functions of flow shaping or water discharge and the aeration of the water flow, there are many possible embodiments for optionally providing the water outlet (3) of the sanitary outlet unit (1) with an extremely thin design.

  • Publication number: 20110011955
    Abstract: A fuel injector that comprises a parallel circuit fuel filtration circuit providing filtered fuel to the control valve. Specifically, a fuel filter is positioned inside the injector within the passage leading to the control valve. Debris is removed from the fuel and filtered fuel is allowed to pass through to the control valve. Unfiltered fuel may be purged from the fuel injector during injection. Alternatively, unfiltered fuel may be removed from the injector via the drain.

    Abstract: A lower fuel injector filter includes a generally planar disk having an annular shape and including a plurality of filter holes. The disk is retained by a valve guide within a valve seat. The disk prevents internally generated contamination particles contained in fuel flowing through the filter holes from reaching a valve and seat interface positioned downstream of the valve guide. The disk may also be retained by a ball valve stop proximate the valve seat.

  • Patent number: 7789329
    Abstract: A backpack sprayer having a tank with a filling opening at the top thereof and a pressure chamber therein is provided with filtering apparatus for preventing particles in the fluid in the tank from entering an inlet port of the pressure chamber located near the bottom of the tank when suction generated by a pump that depends from the bottom of the pressure chamber causes fluid in the tank to flow through the inlet port into the pressure chamber. The fluid pressurized by the pump flows through an outlet port from the pressure chamber for spraying when a valve in the nozzle at the end of a hose communicating with the outlet port is actuated by an operator. The filtering apparatus is provided by a filter in a frame removably captured in a fixture projecting outwardly from the outside of the pressure chamber on opposite sides of the inlet port.
