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 Has electromagnets movable relative to a valve set valve member, which has a pressure compensation surface in a back pressure chamber, from which a pressure compensation connection leads to the upstream side of the valve member.
- Devices of this type serve to keep the pollutant content in the exhaust gases of an internal combustion engine low and to reduce fuel consumption. They are currently becoming increasingly widespread. Examples of the prior art are DE-A-3010167, GB-A-2066930 and DE-A-31 13 986. These documents expressly state that the valve member should be pressure balanced. This must also be striven for so that the actuator can be adjusted with as little force as possible and remains in its respective position by itself. According to DE-A-3010167 and GB-A-2066930, the pressure compensation connection is a bore through the valve member. DE-A-31 13986 is a line which opens between the bypass valve and the suction pipe into the line leading to the bypass valve.
- a seat valve is known from US-A-38 73063, which has a pressure compensation device with which the inlet pressure acting on the valve member is compensated.
- a pressure compensation connection leads from near the narrowest gap between the valve member and the valve seat to a counter pressure chamber into which the valve member projects with a pressure compensation surface.
- 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 compensation connection begins as close as possible to the narrowest gap between the valve member and the valve seat and that the valve seat is designed to widen conically towards the outlet side, the valve member (4) having a region which widens conically towards the outlet side, the area of which Cone angle is larger than the cone angle of the valve seat and with which it can be moved into the conical extension (13) of the valve seat (7).
- 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 makes it possible to change the valve seat independently of the housing design and to adapt it to the particular 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 a part of a housing 1 of a bypass valve 2 into which air flows in the direction of an 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 into a valve seat 7 with a conical area 6.
- a counterpressure chamber 8 serves to equalize the pressure of the valve member, from which a pressure equalization connection 9 leads to a housing gradation 10, which is covered by a flange-like component 11.
- This component 11 forms the actual valve seat 7.
- Its inner circumferential surface forms a conical widening 13 which increases in diameter towards the outlet side of the bypass valve 2. Between its conical widening 13 facing the conical region 6 of the valve member 4 and the conical region 6 there is an angle of 5 to Formed 25 degrees.
