Definitions
- the invention relates to a valve comprising a housing, a solenoid arranged in the housing, a pin movable by the solenoid and a cup-shaped piston connected to the pin, a seal cooperating with a valve seat in the bottom region of the piston and one in the region of the open end the piston arranged seal which seals the piston against the housing.
- valves are used, inter alia, as a diverter valve on the turbocharger in motor vehicles to release a bypass to the suction side in overrun and are thus known.
- rapid opening and closing of the valve is an essential prerequisite.
- when closing it depends on the immediate closing Ver by the application of the piston to a valve seat.
- the valve seat is formed by the housing of the turbocharger to which the valve is flanged.
- the axially displaceable piston must be sealed against the housing.
- the seal At the open end of the piston, the seal has a relatively large sealing lip.
- the size of the sealing lip is required because the piston is displaced with respect to the valve during opening and closing of the valve and the seal must be ensured both at rest and during the piston movement.
- the seal therefore has a larger diameter at the open end than at the bottom of the piston, which makes the projected areas unequal.
- a closing force acting resulting force that holds the piston in the closed position.
- the disadvantage of this is that when opening the valve, the solenoid a corresponding generate large magnetic force in order to additionally overcome the resulting force. As a result, such a valve requires a large-sized solenoid, which must be supplied with a corresponding current.
- the invention is therefore an object of the invention to provide a valve which requires a lower power consumption when opening and closing.
- the cooperating with the valve seat seal has an outer diameter which corresponds approximately to the outer diameter of the seal at the open end of the piston.
- the projected areas of both seals are approximately equal.
- the resulting force is zero.
- the dimensions of both outer diameters differ slightly, preferably maximally 5% and in particular maximally 3%.
- the resulting resulting force is negligible with respect to the magnetic force of the solenoid.
- the seal in the bottom area has a smaller outer diameter than the seal at the open end. Since the sealing lip of the seal rests against the housing of the valve at the open end of the piston in the assembled state, its outer diameter is already reduced in the installed position and thereby approaches the outer diameter of the seal in the bottom region of the piston by the mounting.
- a good media resistance of the seal is given with the use of rubber, preferably a fluorine rubber as sealing material. Another advantage is that such a rubber seal is temperature resistant up to 180 ° C.
- a reliable connection of the seals with the carrier material is advantageously achieved when the rubber for the two seals is vulcanized.
- a seal at the open end of the piston with a high long-term stability is achieved in a further embodiment in that this seal has a base body, which is followed by a radially encircling sealing lip in the direction of the piston crown.
- the base body forms a good basis for the connection of the sealing lip, which guarantees the functionality over the lifetime of the valve.
- this has in a further advantageous embodiment at the open end in the region of the base body of the seal a radially encircling bead.
- the cooperating with the valve seat seal advantageously has a sealing lip. Since this is in contact with another component only in the closed state, the sealing lip can be deformed when moving the piston by the pressure conditions, resulting in a new resultant force.
- Such conditions can be according to a particular avoid advantageous embodiment, when a metallic disc is connected in the bottom region of the piston with this and that the cooperating with the valve seat seal is disposed at least on the outer periphery of the disc.
- the advantage of the metallic disc is that the dimensional stability of the seal is significantly increased.
- Deformations of the seal due to changing pressures can be reliably avoided if the seal at each point of the disc has approximately the same layer thickness.
- the metallic disc can be in a further Substituted particularly simple and secure connect to the piston when it is welded or soldered to this.
- a too reliable connection of the metallic disc with the piston is achieved in that it is connected by means of a locking and fastex connection or a press connection with the piston.
- the press connection can also be achieved in a further embodiment in that disk and piston are pressed against each other by means of the metal pin.
- Both the bottom portion of the piston and the disc have recesses which allow pressure equalization between the interior of the valve and the lines. It has been found to be advantageous to seal the disc against the piston. This is achieved in a simple manner in that the seal from the radially outer edge of the disc extends radially inward to the extent that the seal between disc and piston seals. Due to this configuration also the disadvantages reliably prevented by relative movements between the piston and disc.
- a metal piston also has the advantage of a higher temperature resistance, so that the valve according to the invention a broader field of application, in particular at higher temperatures, can cover.
- the wall thickness of the piston can be made significantly smaller.
- the metal of the piston has a thickness of 0.3 mm to 1 mm, preferably from 0.4 mm to 0.8 mm and in particular of 0.5 mm.
- the piston can be in accordance with a further advantageous Substituted staltung, particularly inexpensive to produce in one step, when the piston and or the disc is a deep-drawn part.
- Fig. 1 is a sectional view of a valve according to the prior art
- Fig. 2 is an enlarged sectional view of a piston of the valve according to the invention.
- Figure 1 shows the valve comprising a housing 1.
- the housing 1 further has a molded flange 3, via which the housing 1 is flanged to a turbocharger, not shown, in the region of the By pass line 4.
- a solenoid 5 with a coil 6 and a metal pin 7 is arranged in the housing 1.
- the Metal pin 7 is connected to a cup-shaped piston 8, which has a seal 10 at the periphery of its bottom 9.
- the seal 10 is located on the Ven tilsitz 11 to close the bypass line 4, so that no medium can flow from the line 4 into the conduit 12.
- a spring 7a presses the piston 8 in the direction of the valve seat 11.
- a further seal 13 with a sealing lip 14 is arranged. If the solenoid 5 is energized, a magnetic force acts on the armature 2, whereby the piston 8 is moved in the direction of the housing 1.
- the sealing lip 14 seals the piston 8 against the housing 1 from.
- the piston 8 according to the invention in Figure 2 also has a seal 13 at the open end of the piston 8 and a seal 10 in the bottom region of the piston 8.
- the seal 13 comprises a base body 15 from which the sealing lip 14 extends in the direction of the piston crown. For improved connection between seal 13 and piston 8 has this in the field of
- Main body 15 a radially circumferential bead 16.
