Definitions

  • the invention relates to a device of the type specified in the preamble of the first claim.
  • the object of the present invention is to provide a parking device of the type mentioned at the beginning with which the delivery quantity adjusting member can be operated in a simple manner. can be adjusted to zero funding.
  • the advantage of this arrangement is that it can be used equally in both distributor and in-line injection pumps. Another advantage is that the delivery quantity adjustment member remains in its zero delivery position until the internal combustion engine is switched to start or operation by turning the starter key in the starter lock. On the other hand, it is not necessary for the internal combustion engine to be equipped with a vacuum pump. Any element of the injection system can be used as the delivery rate adjusting element according to the invention, by means of which the amount of fuel supplied to the combustion chambers of the internal combustion engine can be influenced.
  • Claim 2 represents a preferred embodiment of the invention. It has the advantage that it takes over the components of injection pumps and controllers that have already been used and makes only the counter-stop for the stop of the delivery rate adjustment member changeable. This is possible, for example, in that the counterstop has two sales into which it is moved and held by suitable devices, depending on the position of the starter lock.
  • the counter-stop can be pushed particularly easily into the path of the delivery quantity adjusting member if it is designed according to claim 4.
  • this design has the advantage that no significant changes have to be made to the injection system in order to arrange the lifting magnet, so that this is particularly suitable for retrofitting existing injection systems.
  • the development according to claim 5 solves the task of simply setting the injection pump to zero delivery as long as the on-board electrical system of the internal combustion engine is switched off. This ensures that no electrical energy is required for the lifting magnet when the internal combustion engine is at a standstill. Another advantage is that in the event of a failure of the electrical power supply system of the internal combustion engine, this is turned off automatically, provided that the operating personnel, e.g. B. by resetting the delivery quantity adjustment element is desired.
  • the alternative embodiment of the invention according to claim 6 uses resources of the internal combustion engine, ie lubricating oil or compressed air - if present - to hold the counter-stop in the first rest position (low idling).
  • resources of the internal combustion engine ie lubricating oil or compressed air - if present - to hold the counter-stop in the first rest position (low idling).
  • the counter-stop also clears the path of the delivery rate adjustment element in the second rest position when the operating resources fail.
  • the solenoid valve is designed as a 2-way valve which, depending on the position of the starter lock, regulates the pressure medium flow to the cylinder-piston. Unit releases, causing the piston against the force of a spring like this is moved that its piston rod acts as a counter-stop or connects the cylinder space of the cylinder-piston unit without pressure to the pressure medium return, whereby the piston rod releases the stop.
  • the injection pump controller 1 shown in FIG. 1 has a speed adjustment cable 2 as the delivery quantity adjustment element.
  • a speed adjustment cable 2 as the delivery quantity adjustment element.
  • Such regulators are generally known, so that their structure and function need not be explained in more detail (e.g. Mettig, The construction of high-speed internal combustion engines, de Gruyter 1973).
  • a tension spring 3 acts on the speed adjustment lever 2, as shown in FIG. 2.
  • the speed adjustment lever 2 has a bolt which is rigidly attached to it and serves as a stop.
  • a suitable adjusting element engages on the two fastening elements 7 on the speed adjusting lever 2, with which arbitrarily or the speed adjustment lever 2 is controlled according to special criteria. This is usually a linkage or a Bowden cable with which the operator of the internal combustion engine adjusts its speed. In the case of an internal combustion engine installed in motor vehicles, this means that the accelerator cable operated by the driver acts on the fastening elements 7.
  • the speed adjustment lever 2 has two rest positions.
  • the first rest position forms a counter-stop 5, which is formed by the lifting magnet bolt 6.1 of an electrical lifting magnet 6, which is attached to the controller 1.
  • the lifting magnet 6 is switched on, as a result of which the bolt 6.1 is extended.
  • the second rest position is below the lifting magnet bolt 6.1. For this purpose, this is retracted into the lifting magnet 6 when it is de-energized.
  • the controller 1 is shown in an operating position, i. H. the injection pump connected to it supplies fuel to the internal combustion engine. For this reason, the counter-stop 5 is lowered so that the stop 4 of the speed adjustment lever 2 cannot reach the second rest position - in FIG. 2 - to the left of the current position of the speed adjustment lever.
  • the position shown in FIG. 2 will only hold if a force acts on the two fastening elements 7 on the speed adjustment lever, which overcomes the force of the return spring 3 and that of the control elements.
  • FIG. 3a shows a detailed view of the stop 4 and counter-stop 5, the lifting magnet 6 being switched on and essentially only the force of the return spring 3 acting on the speed adjustment lever 2.
  • the stop 4 abuts the counter stop 5. This means that the internal combustion engine is operated in its low idle state and the speed adjustment lever 2 is in the first rest position.
  • starter lock 8 is adjusted from operating position I to zero position.
  • the power supply to the lifting magnet is thus prevented, so that the counter-stop 5 is moved into the lifting magnet 6.
  • the return spring 3 can move the speed adjustment lever 2 further; namely until the second rest position of the speed adjustment lever 2, which corresponds to the standstill of the internal combustion engine, is reached.
  • This position is shown in Fig. 3b.
  • the counter stop 5 is above the stop. 4 is arranged such that when the internal combustion engine is switched on without the speed adjustment lever being moved, the counter-stop abuts against the stop from above, so that the counter-stop 5 does not block it in its second rest position when the speed adjustment lever 5 is subsequently actuated .
