Definitions
- the invention relates to a valve for the metered admixture of fuel volatilized from the fuel tank of an internal combustion engine to a fuel air mixture supplied to the internal combustion engine via an intake pipe of the type defined in the preamble of claim 1.
- the fuel volatilized in the fuel may not be vented to the outside in some countries, but must be burned by introducing it into the internal combustion engine.
- the venting connection of the fuel tank is connected to a reservoir filled with activated carbon, which takes up the volatilized fuel when the internal combustion engine is at a standstill and again when the internal combustion engine is running delivers.
- the accumulator is connected to the intake pipe of the internal combustion engine via an intake line, where the fuel ampf, the fuel-air mixture is added. The increase in exhaust gas emission that this makes possible requires the fuel vapor to be mixed in only in certain
- the seat valve integrated in the tank ventilation valve is designed to be normally closed.
- the double function of the annular valve member, which also forms the armature of the electromagnet, enables a low movable mass of the armature and thus short switching times of the seat valve.
- Such a stroke adjustment is realized in a known tank ventilation valve of the type mentioned at the outset (DE 38 44 453 AI) in that the valve double seat with valve opening is formed on an intermediate ring clamped in the housing and a bellows with its one end face on the side of the intermediate ring facing the inflow connector attached isc, the other end of which is attached to the bottom of a pot enclosing the bellows with radial spacing.
- the pot edge of the pot merges into an annular collar projecting radially beyond the annular valve opening and having a number of axial bores distributed in the circumferential direction, which are aligned in the axial direction with the valve opening.
- the intermediate ring has on its side facing the pot a sealing seat which surrounds the valve opening on the inside and outside and which cooperates with the ring collar of the pot which acts as a closing member. If the vacuum at the inflow nozzle increases, the bellows contracts. The ring collar approaches the sealing seat and the
- the tank ventilation valve according to the invention with the characterizing features of claim 1 has the advantage, in comparison, of realizing a normally closed seat valve with valve member stroke largely adapted to the pressure difference upstream and downstream of the valve seat, with little manufacturing effort.
- the valve member or the armature is drawn more strongly in the direction of the valve double seat with increasing negative pressure in the intake pipe of the internal combustion engine and thus at the outflow connection of the tank ventilation valve. This suction force counteracts the force of the electromagnet.
- a separate valve seat support is saved, making the valve more cost-effective.
- valve closing spring acting in the suction direction can also be dimensioned much smaller.
- the screw connection between the magnetic core and the magnetic housing enables simple axial displacement of the magnetic core and thus very simple adjustment of the stroke stop for the armature.
- the annular gap nozzle is basically arranged in the recess in the yoke and the valve member or the armature is guided axially displaceably with a small radial distance in the recess by means of a leaf spring held in the valve housing, preferably made of non-magnetic material. This ensures easy guidance of the anchor. The leaf spring is tolerated so that lateral tilting of the armature is prevented.
- the volatilized fuel flowing from the inflow nozzle via the seat valve to the outflow nozzle is guided both through the hollow cylindrical magnetic core and through axial channels between the magnet housing and the valve housing.
- a non-return valve is required, which opens towards the outflow nozzle.
- a check valve is integrated in a simple manner in the valve housing between the valve seat and outflow connection.
- the valve seat of the check valve is formed on the valve housing and its valve member is pressed onto the valve seat with a valve spring which is supported on the outflow connection.
- FIG. 2 shows a longitudinal section of a yoke of return of an electromagnet in the tank ventilation valve according to FIG. 1,
- FIG. 3 shows a plan view of the yoke in the yoke in FIG. 2.
- valve schematically shown in FIG. 1 in longitudinal section for metered admixing of fuel volatilized from the fuel tank of an internal combustion engine to one of the internal combustion engine via an intake pipe
- Fuel-air mixture hereinafter referred to as the tank ventilation valve, is used in a delivery system for introducing volatilized fuel into an internal combustion engine, as described in DE 35 19 292 AI.
- the tank vent valve has a two-part
- Valve housing 10 with a cup-shaped housing part 101 and a cap-shaped housing part 102 terminating this.
- the housing part 101 carries an inflow connection 11 for connection to a ventilation connection of the fuel tank or to a downstream, filled with activated carbon, storage for the volatilized fuel, while the housing part 102 carries an outflow connection 12 for connection to the intake pipe of the internal combustion engine.
- Inflow connection 11 and outflow connection 12 are each arranged axially in the housing parts 101 and 102, respectively.
- An electromagnet 13 is arranged in the interior of the pot-shaped housing part 101.
- Rotation of the magnetic core 15 can be axially displaced in the magnet housing 14.
- the magnetic core 15 is aligned with the inflow nozzle 11, so that the volatilized fuel flowing in here passes directly into the magnetic core 15 and flows through it.
- the axial channels 21, 22 are on the one hand via an annular space 23, which remains between the valve housing 10 and the external thread section 20 of the magnetic core 15, with the inflow nozzle 11 and, on the other hand, via bores 24 which are introduced into the magnet housing 14 near the open end of the magnet housing 14 , in connection with the inside of the magnet housing 14.
- the volatilized fuel emerging from the inflow nozzle 11 also flows around the magnet housing 14 and dissipates any heat generated here.
- the edge of the magnet housing 14 is angled outwards to form an annular support flange 25, which is bent at the end into an axially projecting ring web 26.
- the support flange 25 serves to receive a yoke 27, which covers the magnet housing 14 and rests against the annular web 26 at the edge. 2 and 3 in section and plan view enlarged yoke 27 sits by means of two fitting holes 28 on two retaining pins 29 in the kappenför igen housing part 102, which on the Project part 101 facing the underside axially.
- the yoke 27 is inserted with a precise fit into the support flange 25 with an annular web 26 and clamped therein.
- a leaf spring 30 made of non-magnetic material, for example made of bronze, is clamped between the support flange 25 and the yoke 27, which is centered on the holding pin 29 and carries the armature of the electromagnet 13.
- the electromagnet 13 is used for clocked switching
- the seat valve 31 which is arranged between the inlet nozzle 11 and the outlet nozzle 12.
- the seat valve 31 has a valve double seat 32 (FIG. 2), which is arranged at the bottom of a recess 33 in the yoke 27 on the side facing the inflow nozzle 11.
- the recess 33 is designed such that the base of the recess 33 carrying the valve double seat 32 faces the magnetic core 15.
- the valve double seat 32 coaxially encloses an annular gap nozzle 34 on the outside and inside, which as two symmetrical, semicircular arc gaps 35, 36 in
- Yoke 27 is formed.
- a valve member in the form of an annular disk 37 made of magnetic material interacts with the valve double seat 22 and at the same time forms the armature of the electromagnet 13.
- the annular disc 37 engages with a centering 38 through a circular recess 39 in the leaf spring 30 and is attached to this.
- the annular disc 37 is dimensioned so that its axial thickness is slightly less than the inside depth of the recess 33 and its diameter is slightly smaller than the inside diameter of the recess 33, so that between the
- the outer circumference of the annular disk 37 and the inner jacket of the recess 33 only an extremely small annular gap 40 remains.
- the leaf spring 30 is tolerated so that a lateral magnetic tilting Washer 37 is reliably prevented.
- the annular disk 37 carries a sealing rubber 41 on its side facing the valve double seat 32. In the closed state of the seat valve 31, the annular disk 37 with its sides occupied by the sealing rubber 41 is pressed onto the valve spring by a valve closing spring 49
- valve closing spring 49 is supported on the one hand on the annular disk 37 and on the other hand on an annular support shoulder 50 which is formed on the inner wall of the hollow cylindrical magnetic core 15.
- the free end face of the magnetic core 15 forms a stop 51 for the lifting movement of the ring disk 37.
- outside thread section 20 formed adjusting threads can stop axially 51 and thereby determine the flow rate with maximum open seat valve 31.
- the valve closing spring 49 is dimensioned to be small, since in pressure gradient between the outlet neck 12 and inlet fitting 11, the annular gap nozzle 34 exerts a suction action on the annular disc 37 in the direction of valve shooting, the closing action of the valve spring '49 thus supported.
- the back of the return yoke 27 facing away from the valve double seat 32 is sealed off from the housing part 102 by a sealing ring 42, so that leakage losses occur via the connection of the return yoke 27 and
- Magnet housing 14 can be avoided.
- the outflow connector 12 is snapped into an outflow connector 12 which is coaxially formed on the housing part 102.
- a valve seat 44 of a check valve 45 is formed in the receiving socket 43 on a radially inwardly projecting annular shoulder, on which a valve body 46 is pressed by a valve spring 47.
- the valve spring 47 is supported in an abutment 48 provided in the receiving socket 43.
- the check valve 45 is required if the tank ventilation valve is used in so-called loader engines should .
- the operating state of the internal combustion engine is predetermined, so that the flow rate of volatilized fuel passing through the seat valve 31 from the inflow nozzle 11 into the outflow nozzle 12 is metered accordingly.
- the invention is not limited to the exemplary embodiment described.
- the centering of the leaf spring 30 can also be carried out on the yoke 27 instead of on the housing part 102 by means of pins of the same type.
