Definitions

  • the invention relates to a valve, in particular a fuel injection valve with a lever according to the preamble of claim 1, a lever for a valve, in particular for an injection valve, and a method for producing a lever.
  • valves with levers.
  • the lever rests with a first contact surface on a housing of the valve.
  • a second contact surface is assigned to an actuator.
  • a third bearing surface which is assigned to an actuator, is formed between the first and the second bearing surface. If the actuator presses the lever, the lever pivots around the first bearing surface and moves the actuator with the second bearing surface.
  • the bearing surfaces of the lever are provided with a precise curve. The position of the curves in relation to each other must be precisely defined.
  • the lever is preferably made of hard metal or has at least hardened bearing surfaces. The contact surfaces lead to wear of the associated contact surfaces on the housing of the valve, on the contact surface of the actuator and on the contact surface of the actuator, particularly in the case of a longer service life.
  • a fuel injection valve with an actuator with a lever is known, which is used for transmission to deflect the actuator to an actuator.
  • the object of the invention is to provide an improved hi valve, an improved lever and an improved method for producing a lever for a valve, in particular for a fuel injection valve.
  • the objects of the invention are achieved by the valve according to claim 1, by the lever according to claim 6 and by the method for producing the lever according to claim 9.
  • an advantage of the lever according to the invention is that the lever has a recess on at least one side surface.
  • the lever preferably has recesses on two opposite side surfaces.
  • the recesses have the advantage that on the one hand the mass of the lever is reduced and on the other hand the recesses represent holding recesses for grinding the bearing surfaces of the lever.
  • the recesses hardly influence the stability of the lever, so that the function of the lever is not impaired.
  • the recesses can preferably be used as holding recesses for a holding arrangement of the lever.
  • the contact surfaces of the lever can thus be machined with a single clamping process. In this way, a high precision of the positions of the support surfaces can be achieved. It is therefore not necessary, as before, to hold the lever in two different positions in order to grind the three contact surfaces.
  • the lever has a continuous recess. This results in a large reduction in the mass of the lever.
  • the recess is preferably formed perpendicular to the longitudinal axis of the lever. The continuous recess is then not in the load-bearing area of the lever and the rigidity is not impaired too much.
  • the recesses preferably have holding edges which enable the lever to be positioned exactly with a holding tool. This simplifies the mounting of the lever on a holding tool.

  • Figure 8 shows a support rod and a lever with a lateral holding recess
  • Figure 9 is a perspective view of a lever.
  • Figure 1 shows a partial cross section through a valve 1, which is designed for example as a fuel injection valve.
  • the valve 1 has an actuator 5 which is tensioned via an actuator housing 2 against a valve housing 3 with a clamping nut 4.
  • the actuator 5 is designed as a piezoelectric actuator.
  • the actuator 5 is connected to an actuator plate 6.
  • the actuator housing 2 rests on a first spacer 9 in edge areas, which in turn rests on a second spacer 10, which rests on a bottom surface 11 of the valve housing 3.
  • a He at 7 is arranged between the bottom surface 11 and the actuator plate 6.
  • the lever 7 rests with a first contact surface 12 on the bottom surface 11 and with a second contact surface 13 on an upper side 15 of an actuator 16.
  • the third contact surface 14 is arranged between the first and the second contact surface and bears against the actuator plate 6.
  • the actuator 16 is preferably biased by a spring 17 against the lever 7 and axially movable in a bore 18 of the actuator housing 2. Depending on the embodiment, the spring 17 can also be dispensed with.
  • the actuator 16 has a pin extension 19 which is assigned to a closing element 20.
  • the closing member 20 is assigned to a conical sealing seat 21 which is formed in a drain hole 22.
  • the drain hole 22 communicates with the bore 18 and with a control chamber, which in turn is operatively connected to an injection needle.
  • the control chamber is supplied with fuel via an inlet throttle, which is made available by a common rail accumulator under a predeterminable pressure. If the pressure in the control chamber is high, the injection needle is pressed onto a sealing seat and there is no injection. If the actuator 16 is moved downward by actuating the actuator 5, the closing member 20 is lifted off the sealing seat 21 and fuel flows out of the control chamber via the outlet bore 22 and the bore 18 into an outlet channel. As a result, the pressure in the control chamber drops, so that the injection needle, which is pretensioned by a spring, for example, lifts off the sealing seat.
  • a connection between an injection space and injection holes is thus opened, so that fuel is dispensed from the injection space via the injection holes.
  • the injection chamber is also connected to the common rail memory via a supply line, so that the injection chamber is always supplied with fuel at high pressure.
  • the lever can also be used to transmit a deflection of the actuator directly to an injection needle.
  • the mass of the lever 7 is important since, for example, movements with very high acceleration values occur in a piezoelectric actuator.
  • the contact surfaces of the lever 7 are exposed to large frictional forces, which can lead to abrasion.
  • the lever 7 is preferably made of hard metal. For example, mixtures of 90% tungsten carbide with 10% cobalt are used as the hard metal. Hard metals have the corresponding high stability and high surface hardness, but have a high specific weight.

Abstract

L'invention concerne une soupape comportant un actionneur pourvu d'un levier, un levier et un procédé de fabrication d'un levier. Ce levier est utilisé pour transmettre une déviation d'un actionneur à un organe de réglage, en particulier dans une soupape d'injection de carburant. De préférence, ce levier présente des évidements qui réduisent, d'une part, la masse du levier, sans compromettre la stabilité du levier, et constituent, d'autre part, des évidements de maintien pour un maintien du levier lors d'un processus de rectification. Cette invention offre ainsi l'avantage, d'une part, de réduire la masse du levier et, d'autre part, de simplifier l'usinage d'un levier brut pour la rectification de surfaces d'appui.
