Definitions

  • the invention relates to a device for regulating the idling speed of an internal combustion engine with an intake manifold, in which an arbitrarily actuable throttle valve is arranged, around which a bypass leads with a bypass valve that can be controlled as a function of operating parameters of the internal combustion engine and that regulates a flow cross-section of one of them
  • Electromagnet has valve member displaceable relative to a valve seat, which has a pressure compensation surface in a counter pressure chamber, from which a pressure compensation connection leads to the upstream side of the valve member.
  • DE-OS 30 1 0 1 67 and DE-OS 3113986 may be mentioned as an example of the prior art. Both documents expressly state that the valve member should be pressure-balanced. This is also absolutely to be aimed at, so that the actuator can be adjusted with as little force as possible and remains in its respective position by itself. According to DE-OS 3010167, the pressure compensation connection is a bore through the valve member. DE-OS 3113986 is a line which opens between the bypass valve and the intake pipe into the line leading to the bypass valve
  • the invention has for its object to develop a device of the type mentioned for regulating the idle speed, which enables the most complete possible pressure equalization in any position of the valve member and is therefore to be adjusted with as little force as possible and to be held in its respective position
  • the pressure equalization takes place very precisely if the valve seat has a conical widening towards the outlet side. Apart from this, it has been shown that a bypass valve with such a valve seat is less prone to contamination than the previously known bypass valves.
  • the device is structurally favorable if the valve seat is formed by a housing gradation into which the pressure compensation connection opens and which is covered towards the gap and towards the outflow side by a flange-like component which forms the valve seat and has at least one pressure inlet bore towards the gap.
  • This embodiment also allows the valve seat to be changed independently of the housing design and adapted to the respective circumstances.
  • the pressure compensation connection does not necessarily have to pass through the housing of the device. According to another embodiment of the invention, it can also extend through the valve member to the gap.
  • the invention allows numerous design options. One of them is shown very schematically in the drawing in a sectional view and is described below.
  • the drawing shows part of a housing 1 of a bypass valve 2, into which air flows in the direction of a drawn arrow 3, which leaves the bypass valve 2 behind a valve member 4 in the direction of an arrow 5.
  • the valve member 4 projects with a conical region 6 into a valve seat 7 in.
