Definitions

  • the invention relates to a valve for controlling liquids according to the preamble of claim 1.
  • EP 0 477 400 AI describes a valve which is customary today.
  • an actuating piston of the valve member is slidably arranged in a part of the stepped bore with a small diameter in a stepped bore of the valve housing.
  • a larger piston movable by a piezo actuator is arranged in part of the stepped bore with a larger diameter.
  • a hydraulic pressure chamber filled with a pressure medium is formed between the two pistons, so that a hydraulic translation of a movement of the piezo actuator takes place. This means that when the larger piston is moved by the piezo actuator by a certain distance, the actuating piston of the valve member increases the ratio of the piston diameters
  • a hydraulically operated fuel injector with an injector housing which has a hydraulic fluid inlet and a needle control chamber.
  • a hydraulic unit inside the injector supplies fuel to the injector housing under pressure.
  • the hydraulic unit includes an electromagnetically actuated control valve for the hydraulic fluid and can open and close the hydraulic fluid inlet.
  • a needle valve element includes a hydraulic closure surface exposed to the pressure of the needle control chamber.
  • a needle control valve that uses the electromagnet is provided, which is mounted in the injector housing and connects the needle control chamber to a high-pressure fluid source or can shut it off.
  • the slow response behavior of the hydraulic fluid control valve enables direct control of the fast-responding needle valve by the only fast-acting electromagnet used.
  • an injector is known from Bosch, which is equipped with a servo 3/2-seat slide valve.
  • valve according to the invention with the characterizing features of claim 1 has the advantage that a 3/2-seat valve can be used instead of the known 3/2-seat slide valve, the seats and guides do not have to run to each other.
  • the provision of the second seat enables a hard seal against a slide with a small stroke.
  • the first valve body is designed with a socket in which the second valve body can engage. This ensures a tight interaction between the two valve bodies in a structurally simple form.
  • the second valve body is essentially designed as a ball, which can sealingly engage in the socket of the first valve body.
  • the ball is preferably formed with a cylindrical extension, which takes over the guidance of the second valve body.
  • the cylindrical extension is advantageously formed with a ring at its end region facing away from the ball.
  • a clamping element acts on the ring in such a way that the ball in the pan is pressed for a tight engagement.
  • the first and second valve bodies act as a unit and can be used in a one-piece housing.
  • the guide of the first valve body and the guide of the second valve body are separated from one another, and it is not necessary for the two guides to run relative to one another.
  • valve according to the invention is used in a fuel injection system in which the injection pump and the injection nozzle form a unit (so-called pump nozzle unit (PDE)).
  • PDE pump nozzle unit
  • the injection valve 1 consists of a decentralized pump unit, not shown, and a control unit, not shown.
  • the control unit comprises a piezo actuator, not shown, arranged in a housing, not shown, with a piston 2, which controls a control valve 4 by means of hydraulic transmission 3.
  • the control valve 4 consists of a first body 5, which has a so-called pan 6 at its lower end in the attached figure. This pan 6 is followed by the second valve body 7 in the attached figure.
  • the second valve body consists of a ball " 8, which engages tightly in the pan 6, and a cylindrical extension 9.
  • the cylindrical extension 9 is here guided separately from the first valve body 5 and has a ring 10 formed on the outer circumference of the cylindrical extension 9 at its lower end region in the attached figure.
  • a spring 11 engages the ring 10, which presses the ring 10 and thus the second valve body 7 with the ball 8 against the socket 6 of the first valve body 5.
  • control valve 4 is formed with a first seat 12 and a second seat 13, with which the first valve body 5 and the second valve body 7 come into contact.
  • valve 1 The operation of the valve 1 according to the invention is described below. If pressure is exerted on the piston 2 due to a piezo actuator (not shown) when the piezo actuator is energized, this pressure is transmitted to the first valve body 5 by means of the hydraulic translator 3 in accordance with a predetermined transmission ratio.
  • a piezo actuator not shown
  • this pressure is transmitted to the first valve body 5 by means of the hydraulic translator 3 in accordance with a predetermined transmission ratio.
  • the ball 8 of the second valve body 6 can run a maximum of one stroke H when the control valve 5 is activated or the control valve 5 is deactivated.
  • the stroke is dimensioned in the order of approximately 0.3 mm.
  • the interacting valve bodies 5, 7 each comprise a socket 6 or a ball 8 for an adequate interaction
  • other mutually coordinated geometric shapes than the socket 6 and the ball 8 are of course also conceivable.
